Which cooking oil is the healthiest?. This article explores the latest research and expert advice on the healthiest cooking oils, from olive oil to avocado oil.

Olive Oil and Extra Virgin Olive Oil

Olive oil is made by pressing whole olives and extracting the oil. It is a key part of the Mediterranean diet and the United States is the third largest consumer of olive oil, going through around 406,000 metric tons every year. Both olive oil and extra virgin olive oil have a lower smoke point than other oils, making them better suited for medium-heat cooking. However, refined or pure olive oil may be more suitable for high-temperature cooking.

Olive oil is high in healthy monounsaturated fats and oleic acid, which can prevent heart disease and lower cholesterol. Extra virgin olive oil is the least processed version, so it retains more of the beneficial nutrients and antioxidants. These antioxidants can reduce oxidative damage that can cause inflammation and lead to diseases like cancer or diabetes.

While many studies have reported the cardiovascular health benefits of the Mediterranean diet, which is rich in olive oil, a 2019 Cochrane review found that there is still uncertainty around its effects, with the evidence for benefits being low or moderate.

Canola Oil

Canola oil is made from the seeds of the canola plant, which is a genetic variation of the rapeseed plant. It is low in saturated fat and high in monounsaturated fat, making it a healthier option compared to many other cooking oils. Canola oil has a relatively high smoke point, making it suitable for high-heat cooking like stir-frying and sautéing.

Numerous studies have shown that replacing saturated fats with canola oil can help lower LDL (bad) cholesterol levels and reduce the risk of heart disease. A 2018 review in the Journal of the American College of Nutrition concluded that canola oil consumption is associated with improved cardiovascular disease risk factors.

Avocado Oil

Avocado oil is pressed from the flesh of avocados and is high in monounsaturated fats, similar to olive oil. It has a mild, nutty flavor and a high smoke point, making it suitable for high-heat cooking methods like grilling and roasting.

Avocado oil is rich in vitamins and antioxidants, including vitamins A, D, and E. Studies have shown that it can help lower LDL cholesterol and triglyceride levels, while increasing HDL (good) cholesterol. A 2019 review in the Journal of the American College of Nutrition found that avocado oil consumption was associated with improved cardiovascular disease risk factors.

Coconut Oil

Coconut oil is made by extracting oil from the meat of mature coconuts. It is high in saturated fat, which has been linked to increased cholesterol levels and a higher risk of heart disease. However, some research suggests that the specific type of saturated fat in coconut oil, called medium-chain triglycerides (MCTs), may have some health benefits.

The evidence on the health effects of coconut oil is mixed. Some studies have found that it can help increase HDL (good) cholesterol and improve markers of metabolic health, while other research has shown that it can raise LDL (bad) cholesterol levels. Overall, the consensus among health experts is that coconut oil should be consumed in moderation as part of a balanced diet.

Grapeseed Oil

Grapeseed oil is extracted from the seeds of grapes and is low in saturated fat while high in polyunsaturated fat. It has a light, neutral flavor and a high smoke point, making it suitable for high-heat cooking and frying.

Grapeseed oil is rich in vitamin E and antioxidants, which can help protect against oxidative stress and inflammation. Some research has suggested that it may also have cardiovascular benefits, such as lowering cholesterol levels and improving blood vessel function. However, more research is needed to confirm these potential health effects.

Peanut Oil

Peanut oil is extracted from the seeds of peanuts and is high in monounsaturated and polyunsaturated fats. It has a neutral flavor and a high smoke point, making it suitable for high-heat cooking methods like deep frying.

Peanut oil is low in saturated fat and has been associated with various health benefits, including improved cholesterol levels and reduced risk of heart disease. However, it is important to note that peanut oil can be a common allergen, so those with peanut allergies should avoid it.

Sesame Oil

Sesame oil is pressed from sesame seeds and has a distinctive nutty flavor. It is high in monounsaturated and polyunsaturated fats, as well as antioxidants like sesamol and sesaminol.

Sesame oil has a relatively low smoke point, making it better suited for low- to medium-heat cooking, such as sautéing and dressing salads. Some research has suggested that sesame oil may have anti-inflammatory and cholesterol-lowering properties, but more studies are needed to confirm these potential health benefits.

What are the healthiest cooking oils? It’s a question you may have found yourself asking if you like to add a splash or two of liquid gold into the pan when cooking meats and vegetables. But not all oils are created equal, and with dozens of bottles and jars lining the grocery store shelves, trying to decide on which cooking oil to buy can feel more than a little overwhelming.

“Over the past 10 years, the landscape of cooking oils has changed,” says Dr. Jo Ann Carson, a professor of clinical nutrition at the University of Texas Southwestern Medical Center in Dallas. She points to the wider availability of oils such as grapeseed oil and the fairly recent arrival of coconut oil and avocado oil as examples of how the market has evolved. “With so many cooking oils, it can be difficult to make sense of the latest health headlines about dietary fat in general. ”

The good news is, selecting the right oil to cook with doesn’t need to be a challenge. To help make life easier, we’ve checked out the latest research and spoken to nutrition experts to lift the lid on cooking oils and their health benefits, from reducing heart disease to maintaining healthy body weight.

Read on to get the lowdown on which oils to avoid and which to include to benefit your overall health.

Should you use cooking oils?

According to the Dietary Guidelines for Americans (2020-2025), oils are an essential part of a healthy diet. We need the fatty acids in cooking oils to help us:

• Absorb vitamin A, D, E and K 
• Support a healthy body weight
• Aid healthy cell growth
• Reduce the risk of heart disease

(Image credit: Getty Images)

All oils contain three types of fatty acids: 

• Monounsaturated fat: Healthy fat found in olive oil, nuts and seeds  
• Polyunsaturated fat: Healthy fat found in oily fish, vegetable oils, nuts and seeds
• Saturated fat: Unhealthy fat found in butter, lard, coconut oil and palm oil

Each oil is categorized based on which type of fatty acid is the most prominent. For example, olive and canola oils are mostly monounsaturated fat, while corn and soybean oils contain mainly polyunsaturated fat. On the other hand, coconut oil is predominantly saturated fat, which is linked to high cholesterol and heart disease.

Even healthy oils are fat, says the Cleveland Clinic, so limiting any oil consumption to a healthy amount, around 27g a day, is essential. 

To help you select some of the healthiest oils while still pleasing your taste buds, here is a rundown of nine cooking oils.

Olive oil & extra virgin olive oil

Olive oil is made by pressing whole olives and extracting the oil, and is a key part of the Mediterranean diet. The United States is the third largest consumer of olive oil, getting through around 406,000 metric tons every year. 

Both olive oil and extra virgin olive oil have a lower smoke point than other oils, so they are better for medium-heat cooking. “The oil cannot withstand very high heat before it starts to burn and smoke,” says Carson. “Refined, or pure, olive oil may be more suited for high-temperature cooking.”

Jo Ann S. Carson, PhD, RD, FAHA recently retired as a Professor of Clinical Nutrition. For over four decades at the University of Texas Southwestern Medical Center she focused on nutrition education, helping students gain knowledge and skills to improve their own nutritional habits and those of their patients to prevent chronic disease, including cardiovascular disease.  She has chaired the American Heart Association’s Nutrition Committee and continues to serve on an Academy of Nutrition and Dietetics’ Evidence Analysis project related to diet and heart health.  

Carson also points out that because extra virgin olive oil offers more flavor than olive oil, it’s a good option for sautéing vegetables, dipping bread or preparing salad dressings and marinades.

Olive oil is high in healthy monounsaturated fats and oleic acid, which can prevent heart disease and lower cholesterol. It’s also low in polyunsaturated fat.

Extra virgin olive oil is the least processed version of olive oil, so it keeps more of the nutrients and antioxidants. A 2018 International Journal of Molecular Sciences review points out that these antioxidants reduce oxidative damage that can cause inflammation, leading to diseases such as cancer or diabetes.

Although many news headlines consistently report that the Mediterranean diet, rich in olive oil, is critical to good cardiovascular health, a 2019 Cochrane review says there is still ‘uncertainty’ around its effects with the evidence for benefits low or moderate.  

Dr. Alice H. Lichtenstein is Senior Scientist and Director of the Cardiovascular Nutrition Team at the HNRCA. Dr. Lichtenstein is the Stanley N. Gershoff Professor of Nutrition Science and Policy at the Friedman School of Nutrition Science and Policy and holds appointments as Professor in the Institute for Clinical Research and Health Policy Studies at Tufts Medical Center, Professor of Medicine at Tufts University School of Medicine, and Professor in the Department of Public Health and Family Medicine at Tufts University School of Medicine.  

Avocado oil

Avocado oil has a mild flavor similar to the fruit it’s made from, and the oil can withstand high cooking temperatures, making it suitable for sautéing, grilling, roasting or using in salad dressings.

Avocado oil has one of the highest levels of monounsaturated fat among cooking oils, second only to olive oil. Like olive oil, avocado oil is also low in polyunsaturated fats and rich in oleic acid.

We need more research to be sure of avocado oil’s health benefits, but early studies show that it can reduce cholesterol, improve cardiovascular health, benefit eye health and help the body absorb other essential nutrients. It may even improve the symptoms of arthritis, as one 2019 systematic review published in the International Journal of Rheumatic Diseases shows.

Compared with other vegetable oils, avocado oil has a higher saturated fat content (20%). However, this percentage is much smaller than the percentage of saturated fat in butter, lard or tropical oils, such as coconut or palm oils.  

“Avocado oil is a fine oil to use, although it tends to be more expensive than other oils and may be harder to find,” says Alice Lichtenstein, a professor of nutrition science and policy and director of the cardiovascular nutrition laboratory at the Tufts University Human Nutrition Research Center on Aging in Boston.

Canola oil

This neutral-flavored oil comes from a plant called rapeseed. “It’s a versatile and practical cooking oil that’s not very expensive and can be used in a variety of ways, from baking and grilling to stir-frying and making salad dressings,” says Carson.

Canola oil also has relatively high monounsaturated fat content and is a good source of polyunsaturated fat. It also has the lowest level of saturated fat among cooking oils and is one of the few oils that contain a good plant-based source of omega-3 fats, a beneficial type of polyunsaturated fat.

A review of studies published in the journal Nutrition, Metabolism & Cardiovascular Diseases Reviews found that canola oil can ‘significantly’ reduce people’s risk of heart disease.

Coconut oil

Made from the fruit of the coconut palm tree, coconut oil is a white solid at room temperature with a consistency resembling that of butter or shortening, rather than liquid oil. Unrefined coconut oil can be used for medium heat sauteing or baking, while refined coconut oil can be used with high temperatures. 

Despite marketing claims that coconut oil is a healthy option, it’s high in saturated fat, containing more than the same amount of butter or lard. As a result, it’s not included in the Dietary Guidelines for Americans or recommended by the American Heart Association. 

However, a 2021 review in the Journal of the Science of Food and Agriculture maintained that coconut oil has been proven to reduce the risk of cancer, diabetes, and cardiovascular disease, as well as improving the skin. It claims that Western science needs to do more research into the benefits of coconut oil.

“Coconut oil does not have any unique heart-health benefits, and its ‘halo effect’ — meaning its perception by the public as a healthful food — is probably not justified from a scientific perspective”, says Lichtenstein. “There is no reason to use coconut oil rather than unsaturated oils, and there are potential disadvantages from its high content of saturated fat”.

Until more substantial research, it’s probably safer to steer clear of coconut oil if you want to limit saturated fats in your diet.

Grapeseed oil

This versatile cooking oil is extracted from grape seeds left over from wine making. A favorite of chefs and foodies, grapeseed oil has a mild flavor that can be combined with other, stronger flavors. It’s a good all-purpose oil for sautéing and roasting, or in salad dressings. Store it in the refrigerator along with walnut oil so it doesn’t become rancid, advises the Cleveland Clinic.

Grapeseed oil is rich in vitamin E, which is a powerful antioxidant. It also contains very high levels of omega-6 polyunsaturated fat. While some evidence, such as a study published in the Missouri Medicine journal, points to omega-6 fats increasing the risk of obesity, autoimmune diseases, asthma and allergies, another study published in Food & Function found that the type of omega-6 fats found in rapeseed oil can lower inflammation. So we need more research to discover how grapeseed oil can impact our health.

Peanut oil

A flavorful oil with a pale color and nutty aroma, peanut oil comes from the edible seeds of the peanut plant. According to food experts, it can withstand high heat and is a good choice for cooking Asian-inspired meals and stir-fries.

Among cooking oils, peanut oil has the highest monounsaturated fat content and similar levels of polyunsaturated fat to canola oil.

Like grapeseed oil, peanut oil is rich in the antioxidant vitamin E. However, it also contains very high levels of omega-6 polyunsaturated fat, so some health experts warn against using it until we know more about the effects of omega-6 fatty acids on our health.

Sesame oil

Often used in Asian, Indian and Middle Eastern cooking, sesame oil comes from pressed sesame seeds. Sesame oil lends a nutty flavor to any dish, especially toasted sesame oil, which has a darker color and bolder flavor. Refrigerate sesame oil after opening it.

“It’s not usually used as a cooking fat and is used more for its intense flavoring,” says Lichtenstein. “It’s a good mix of polyunsaturated fat and monounsaturated fat.”

Sesame oil contains sesamol, a key natural phenol known to have antioxidant and anti-inflammatory properties. According to the American Oil Chemists’ Society, sesamol can reduce the risk of cancer and cardiovascular disease. A small randomized control trial published in the Journal of the American College of Nutrition found that it may help to regulate blood sugar levels in people with type 2 diabetes. 

Vegetable oil

“Historically, vegetable oil has typically been soybean oil,” says Carson. “But these days, the term also may be used for a blend of different oils.” Vegetable oil made from soybeans is a neutral-tasting oil that does not have much flavor, but it’s a versatile, all-purpose cooking oil for sautéing and frying or making salad dressings.

Soybean oil is primarily polyunsaturated, with just 15% saturated fat. As a bonus, soybean oil contains omega-3 fats, which are heart-healthy fats often found in salmon and sardines but are less common in plant-based food sources.

Sunflower oil

Light in color and neutral in flavor, sunflower oil has one of the highest concentrations of polyunsaturated fat among cooking oils. It also contains some monounsaturated fat and is low in saturated fat, making it an overall heart-healthy option. Sunflower oil is an excellent all-purpose oil because it can withstand high cooking temperatures, so it can be used for roasting, frying and deep-frying.

There are three types of sunflower oil available in the U.S. for home cooking, each of which have been modified to have different fatty acid profiles:

• High linoleic acid
• Mid-oleic
• High oleic 

Modifying sunflower oils to have higher linoleic or oleic acid levels changes how these oils behave during cooking. While all three have the same levels of saturated fat, high oleic contains more monounsaturated fat and high linoleic contains more polyunsaturated fat.

A diet with plenty of oleic acid is linked to lower cholesterol and a lower risk of heart disease. It may also increase good cholesterol. As a result, the U.S. Food and Drug Administration has approved health claims for high oleic sunflower oil. 

What is the healthiest cooking oil?

According to the Mayo Clinic and the Cleveland Clinic, olive oil or extra virgin olive oil is the go-to cooking oil for a heart-healthy life, although other oils can provide similar benefits, such as vegetable oil. In addition, the Dietary Guidelines for Americans recommends switching from butter, lard, shortening or coconut oil to vegetable oil when cooking to reduce saturated fat in the diet.

5 Best Healthy Cooking Oils, According to Nutritionists—and Which Ones to Avoid or Use in Moderation

No matter your diet, you likely cook with some amount of oil: It’s often an essential ingredient in preparing vegetables, meats, eggs, sauces, and more, providing texture, lubrication, and taste, too. But not all cooking oils are created equal when it comes to nourishment.

“A healthy cooking oil is an oil that is predominately made of monounsaturated fatty acids or omega 3 fatty acids,” explains Kylene Bogden, R.D. and co-founder of the nutrition coaching group FWDfuel.

But an oil’s composition in the bottle is only part of the picture when it comes to its healthfulness. Smoke point, or the temperature at which the oil is no longer stable, has long been considered another critical piece. Oils have a range of smoke points, and prevailing wisdom says that you shouldn’t use them to cook at a temperature above this point. So depending on what you’re cooking, the healthiest cooking oil is also going to be one that stands up to high heat.

“Each oil has a different smoke point, which is the temperature at which the oil begins to break down and produce harmful compounds,” explains Noah Quezada, R.D.N. and CEO of Noah’s Nutrition. “It’s important to use oils with a high smoke point when cooking since overheating oils can lead to the release of harmful chemicals.”

That said, other data seems to challenge these common notions about smoke points. For instance, a study published in the journal ACTA Scientific Nutritional Health, found that olive oil is not only safe to cook with at high temperatures, but it is also one of the most stable and safest cooking oils available.

The Washington Post also challenged the smoke point issue. “There’s more at play,” it noted. “There are plenty of other things to absorb the heat and energy — the pan, the food, the moisture of the meat or vegetables. Water or a sauce with the food can help, too. The oil is not taking the brunt of the heat, and it’s unlikely that the temperature of the oil will equalize to that of the oven itself.”

Whatever conclusions you draw from the available data on smoke points, to benefit from a cooking oil’s nutritive potential, you must also actually want to use it, of course.

Of course, to benefit from a cooking oil’s nutritive potential, you must actually want to use it. Wendy Bazilian, DrPH, R.D.N, recommends selecting your oils with this three-prong test: “Are they nutritive oils themselves and can they handle the heat? Not to mention do you like the flavor of them so you’d gain the benefits by actually using them?” She notes that tasty oils “can help make foods we need more of in the diet—like vegetables—more delicious and perhaps easier thus to eat more of. ”

Read on to learn what nutritionists say are the best healthy cooking oils—as well as some oils to avoid.

What makes cooking oil healthy?

A healthy cooking oil is one that is low in saturated and trans fats, and high in monounsaturated and polyunsaturated fats. “When any of these replace a less healthy oil or are blended with another oil, that can be a win for health,” Bazilian explains.

The American Heart Association recommends choosing oils with less than four grams of saturated fat per tablespoon, and no partially hydrogenated oils or trans fats, notes Amy Adams, R.D.N.

The healthiest cooking oils to use

Olive oil

Extra-virgin olive oil is often considered a great oil for cooking because it is filled with heart-healthy monounsaturated fats, explains Dana Ellis Hunnes, a senior dietitian at UCLA Medical Center and the author of Recipe For Survival: What You Can Do to Live a Healthier and More Environmentally Friendly Life. These are anti-inflammatory and beneficial for lowering LDL cholesterol levels. “However, it does not have a high smoke point and is best used as a dressing on salad, or a topper for pasta, or for a low-slow cook,” she says. “Its low smoke point is due to the fact it contains more of the microparticles from the olives themselves—[resulting in] the greener color.”

Regular olive oil also is healthy, and is still full of monounsaturated fats, but not quite as anti-inflammatory because it consists of refined olive oil that has been enriched with virgin olive oil. “It can however be cooked at a higher temperature, higher smoke point, and therefore is better for pan-frying and searing,” Hunnes explains.

On the flip side, the ACTA study found extra virgin olive oil was “demonstrated to be the most stable oil when heated.” It is also included on the U.S. Department of Agriculture’s (USDA) list of recommended oils to safely fry with.

Peanut oil

Especially popular in Asian cuisines, this is another healthy monounsaturated oil that has a very high smoke point and can be used to deep-fat fry, although such a preparation method would “negate its health benefits,” Hunnes says. “It is an oil that does not have much flavor, despite its peanut derivative,” she adds, and that can be desirable for taste neutrality and versatility in dishes.

Avocado oil

Refined avocado oil has a high smoke point of 520 degrees (and unrefined at 375 degrees). It’s also filled with monounsaturated fats, and it’s good for baking as it’s nearly flavorless.

“Avocado oil is a good cooking oil and carries along with it some, though certainly not all, of the nutrition that the whole avocado has,” Bazilian says. (As a practical matter, Adams adds, “though avocado oil is fine for sautéing, it is quite expensive.”)

Canola oil

Canola oil has a smoke point of 400 to 450 degrees and is low in saturated fat. And because it doesn’t have much flavor, Quezada says, “this makes it a good option for recipes that call for subtle flavors.”

Chia oil

This oil is less familiar to casual cooks in the U. S. but is starting to make its presence known, Bazilian says. She recommends it as a healthy oil because “it has a very high smoke point and is stable at high temps due to its high antioxidants that remain in the cooking oil.”

What makes an “unhealthy” cooking oil?

Although our reporting suggests plenty of subjectivity even among registered nutritionists, some oils are typically considered unhealthy because they contain high levels of saturated and/or unhealthy unsaturated fats. “Partially hydrogenated oils found in items like shortening are the most unhealthy because they usually contain trans fats,” Adams explains. “Trans fats are man-made fats created when hydrogen is added to vegetable oil.”

Trans fats simultaneously lower your “good” cholesterol (HDL) while raising your “bad” cholesterol (LDL), and have been linked to heart disease. To determine if you are cooking with trans fats, look out for “partially-hydrogenated oil” on the ingredients list.

Without even looking at the label or researching the ingredients, you can tell which oils contain saturated fat because they are solid at room temperature, Adams explains.

Bogden adds, “Oils that are less than ideal to use are very refined and contain a higher omega 6 to omega 3 ratio, a ratio that if consumed routinely can contribute greatly to inflammation.”

Cooking oils to use in moderation

• Palm oil is high in palmitic acid, “a type of saturated fat that has been linked to increased risk for heart disease and other chronic illnesses,” Quezada explains.
• Butter is high in saturated fat as well as trans-fatty acids, “which have been shown to increase the risk for heart disease,” he says.
• Sunflower oil has a high smoke point, “but it contains a lot of omega 6 fatty acids,” according to Lisa Young, Ph.D. and registered nutritionist. “Too many omega 6s are considered pro-inflammatory, and eating too many omega 6s without balancing with omega 3s could lead to inflammation, so you may want to limit this oil. ”
• Margarine contains an unhealthy combination of saturated and trans fats.

What’s the deal with coconut oil?

Among the many dietitians who contributed feedback for this story, coconut oil was controversial. Some called it healthy; others didn’t.

“Depending upon who you ask, some people love coconut oil while others think it should be avoided. This is because of its high saturated fat content,” Dr. Young explains. “Coconut oil is mostly saturated fat as compared to other plant oils. The American Heart Association advises replacing foods high in saturated fat like coconut oil with foods that are high in unsaturated fats like olive oil.”

Because it has a high smoke point, it’s good for cooking—but because of its high saturated fat content, it should be consumed in moderation, she says.

Bazilian agrees with the approach. “Coconut oil, which has received lots of attention, is actually a saturated fat, but shorter chain and can be used in moderation,” she says.

How to choose 5w40 engine oil for a car

Before you buy engine oil, you need to check tolerances. Compliance must be international classification (SAE, API, ILSAC) or European (ACEA). Even for an experienced car owner, it is important to make sure that the composition is compatible with your car. This can be done using the information on the bottle and in the machine’s instruction manual. The frequency of oil change is also individual, since the maintenance interval with an oil change can be in the range from 10,000 to 25,000 km. High mileage vehicles require higher viscosity oils. In addition, it is worth considering which oil was used before the current change. The fact is that a cocktail of synthetics and mineral oil or compositions of different viscosity has a detrimental effect on the engine in general.

Expert reviews of 5w40 engine oils for car

At the request of the editors, Sergey Dyachenko shared his opinion about 5w40 engine oil with readers.

– Oils from the high viscosity class really should be like this: the viscosity index must remain approximately the same at the first fill and at the end. The thing is that going beyond the limits of viscosity change allowed by the SAE class significantly increases the gluttony of the engine. Therefore, it is better not to save on oil. It is also worth considering that 100% high-viscosity synthetics have higher energy-saving properties than other formulations. I recommend switching to 5W40 if the car’s mileage has exceeded 100,000 km. A more viscous oil will delay the inevitable wear of parts, says the owner of a car service.

FAQ

Tolerances checked, but still have questions about oil? This article comes to the aid of readers, where the answers are given by an expert.

How often should the oil be changed?

— In addition to the recommendations in your vehicle owner’s manual, it is important to consider engine wear. Cars that have seen life, as well as those that are actively used in winter, need to change the oil more often.

Is the oil responsible for the temperature of the parts?

– High-quality composition protects parts from friction, thereby minimizing excessive heating. All this significantly extends the life of the car.

What are the additives in engine oil?

– Each additive has its own purpose: anti-wear additives reduce friction, detergents clean parts, and there are those that are responsible for reducing fuel consumption. Each manufacturer makes their own mixture using high quality additives that do not precipitate and improve the performance of the oil.

Engine oils with viscosity 5W-30 and 5W-40 are among the most popular and are used in the vast majority of passenger cars. Such fluids can be used as all-weather fluids and are capable of operating in a wide range of temperatures. Oils with these viscosity indices are close in performance; in many car models, materials of both classes are allowed. Each type of lubricating fluid has certain advantages and disadvantages, so drivers often find it difficult to choose one or another option. We propose to consider in more detail the features and characteristics of these materials and find out which is better – 5W-30 or 5W-40.

Specifications for 5W-30 and 5W-40 oils

Lubricants of these classes have the same low temperature viscosity index – 5W. Therefore, the disputes of motorists about which oil is better in winter – 5W-30 and 5W-40 – are devoid of any meaning. In the cold season, these materials work equally effectively. The pour point is -44 °C for both types of oils. The main difference between them lies in the high temperature viscosity, which is indicated by a numerical index to the right of W. The higher this indicator, the thicker the lubricant will be at engine operating temperatures (during and after warming up). Depending on the composition, manufacturer and properties of additives, motor oils 5W-30 and 5W-40 at a temperature of +100 ° C have a kinematic viscosity within 9.3–12.5 and 12.5–16.3 mm2/s. The difference is almost 30-35%.

Comparison of laboratory analyzes of 5W-30 and 5W-40

The difference between engine oils of these viscosity grades can be clearly seen by reading the results of laboratory tests of lubricants from one of the popular Russian manufacturers:

• Kinematic viscosity at 40 ° C – 55 .98 (5W-30) and 79.21 mm2/s (5W-40).
• Kinematic viscosity at 100°C – 10.13 (5W-30) and 13.37 mm2/s (5W-40).
• Pour point – -44 °C for both types of oils.
• Flash point – +232 °C (5W-30) and +235 °C (5W-40).
• Dynamic viscosity CSS at -30 °C – 4040 (5W-30) and 5490 units (5W-40).

Which oil has the best performance

Each engine is designed to run on a specific type of oil. The lubricant recommended for one motor may not be compatible with another unit. Some engines work better with oils that have increased high temperature viscosity (in this case, 5W-40). Other engines under the same operating conditions require the use of 5W-30 motor oil, which creates a thinner oil film when it reaches operating temperature. For this reason, it is impossible to unequivocally answer which oil is better – 5W-30 or 5W-40. The best viscosity grade for a particular engine is the one recommended by the car manufacturer.

Which viscosity is best for winter

5W-30 and 5W-40 oils do not differ much in performance at low temperatures. Their fluidity and pour point are almost the same. But these characteristics only matter when starting the engine and warming it up. Then, when the engine reaches operating temperature (above +100 ° C), these oils will work differently. 5W-30 will be more fluid, the oil film thickness will be thinner, and the liquid will begin to drain faster from metal surfaces. 5W-40 car oil, on the contrary, will be thicker, and the oil film will be thicker. Accordingly, the choice of a specific viscosity class, as in the previous case, will depend on the type of engine and the recommendations of the vehicle manufacturer.

Used engine oil

Engines that have a significant output differ from new engines in increased clearances in the cylinder-piston groups. Oil must completely fill them so that dry friction does not occur when the cylinders move. This task is better handled by 5W-40 oil, which at high temperatures has less fluidity and flows more slowly from surfaces. It creates a thicker oil film, which is especially important for engines with high mileage exceeding 200-300 thousand kilometers. Auto oil 5W-30 in this case will be less preferable. Such a fluid will be too fluid at operating temperatures, due to which the gaps between the pistons and the cylinder walls will not be completely filled with lubricant. This will increase the risk of local breaks in the oil film, which will lead to dry friction and overheating of the rubbing engine parts.

Is it possible to mix 5W-30 and 5W-40

Mixing engine oils that differ in characteristics, composition and brand is in most cases undesirable. Therefore, before servicing the car, you should purchase a lubricant with a certain margin and always carry a canister of the same car oil in the trunk in case of emergency topping up. But in some situations, when it is urgent to add lubricating fluid to the engine in order to prevent oil starvation of the internal combustion engine, this is allowed – for example, if you find a leak on the road and are forced to seek help from other drivers who may have oil of a different viscosity. It is necessary that both motor oils have the same base (synthetics or semi-synthetics). It is also desirable that both materials be produced by the same manufacturer. When mixing 5W-30 and 5W-40 oils, the final viscosity and frost resistance of the “two-component” fluid will depend on the proportions of both materials. For example, if you pour these oils into the engine in a ratio of 90:10, then the final mixture will be close to 5W-30 in terms of characteristics.

Differences between synthetic and semi-synthetic oils

According to the SAE classification, which standardizes the viscosity characteristics of automotive oils, there is no perceptible difference between synthetics and semi-synthetics if the materials belong to the same viscosity class. Both types of motor oils are subject to the same requirements. This means that 5W-30 class synthetic and semi-synthetic fluids will show almost the same flow characteristics at low and high temperatures. Therefore, the type of base (synthetics or semi-synthetics) can be chosen at your discretion. The main thing is that the fluid has the necessary tolerances, and its characteristics meet the requirements of the manufacturer of your car.
