Can I use 5W-20 instead of 5W 40?

Can I use 5W-20 instead of 5W 40?

The quick answer is no you should not use 5w20 when 5w40 is recommended by manufacturer. The thinner oil may not lubricate the internal engine as designed.

Can I mix 5w40 and 5W20?

It is still not a good idea to mix two different brands of oil, even if they have the same viscosity. The oil you use should be the grade recommended by your car manufacturer. However, if you mix two different brands of motor oil, you could damage your vehicle.

What Oil Can you substitute for 5W-40?

What Oil Can I Use Instead Of 5w40? The oil you use should be VW 502 certified, so a 5W-30, 0W-30, 5W-40, or 0W-40 will work just fine.

Which is better 5W-20 or 5W-40?

5w-20 is even thinner than the 5w-40. It flows much better but is too thin to properly lubricate an engine that requires a slightly thicker, 40 grade oil.

Can I use 5W-20 in summer?

Theres nothing wrong with using 5w-20 in the summer, in fact 5w-30 wouldn’t be any better, remember that the “w” stands for “weather”. Unless your pulling trailer or a heavy load, you’ll be just fine.

The importance of choosing the right engine oil quality and viscosity for your car or truck – VOTD

Is 5w20 OK in winter?

5W20 motor oil is another low-temperature grade typically recommended for winter use, with a 10W-30 as an alternative for higher temperatures. This oil type is common because it provides the best fuel economy, saves fuel consumption, and has fewer exhaust emissions.

Is 5w20 oil too thin?

5W-20 oil is a relatively thin oil at very high temperatures, but it still provides decent protection and lubrication at a normal operating temperature in moderate climates. However, if you drive a lot in extremely higher temperature settings and hotter climates, you may want to switch to a higher oil viscosity grade.

Is 5w40 too thick in the winter?

Is 5w30 Or 5w40 Better For Winter? The 5W30 can be used by a variety of vehicles, in different temperatures, and in different climates. However, it is best suited for colder temperatures when used in a vehicle. The higher mileage engine sand used in 5w40 is often better at withstanding warmer temperatures than 4w40.

Can you put 10W 40 in a 5W 20?

The Ranger said that you can mix 10W & 30W to get 20W, or you can mix 5W20 & 10W40, but you don’t want to mix 10W & 30W. The answer is yes, but not straight weights or multigrades.

Is 5w40 good for winter?

5w40 and 5w30 motor oils have winter viscosity grades of five, meaning they are effective down to temperatures of -30°C, and are more viscous at very low temperatures, compared to, say, 10w40 oils.

Is 5w40 better for high mileage cars?

5w30 can be used by different type of vehicles and in different range of temperatures, but is ideal for colder temperatures. 5w40 is often used in higher mileage engine sand performs better in warmer temperatures.

What happens if you use wrong engine oil?

You might notice a few oil spot in your garage or under your car because using the wrong oil can lead to leaks, or you might become aware of a burning smell while driving. If the oil isn’t working as it should engine parts might not be lubricated well enough and cause friction, which can burn the oil.

Is 5w40 good for summer?

5w40 is better for starting your engine at low temperatures as it flows more easily at these temperatures. When the engine is running and hot, 5w40 and 10w40 have high viscosities and are equally effective in protecting against engine wear.

Is it OK to top up different engine oil?

You can add any engine oil as long as it has the right specifications — preferably with an official approval of the OEM (Original Equipment Manufacturer). Not the brand, but the specification and viscosity indicated in your car’s manual are your reference for using the right oil.

Can I top up oil with different oil?

It is only recommended to top up your car with oils of different grades when you are running low in the middle of nowhere or the oil that you first used is no longer available in the market. Further, it is advisable not to mix two different brands of oils as their additives may or may not be compatible.

Is it OK to mix 5W20 synthetic oil?

The 5W20 oil performs better in cold temperatures, though. So what will happen if your mix both oils together? Both oils being of different viscosity and additive components, will not entirely mix to form a single oil mixture. If you mix both oils for emergency use, your engine might not be immediately affected.

Will thicker oil damage my engine?

Using oil that is thicker than recommended may lead to a decrease in fuel economy, a higher load on your engine, and even a shorter life for your engine. Conversely, using thinner, lighter-weight oil than recommended can cause excessive wear and shorter life.

Is Thicker oil better for older engines?

A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil – 10W – can help protect worn engine bearings as well.

What is thicker 5W30 or 5W20?


When it comes to their higher operating temperature performance, 5W30 motor oil performs slightly better than 5W-20 and is a thicker oil than its counterpart. 5W30 motor oil would be more robust and not break down very easily at a higher temperature.

What does 5W-40 stand for?

Two-digit oils like 5W-40 are multi-grade oils; the oils have a viscosity rate of 5 at 0 degrees Fahrenheit and the viscosity properties of 40 at 212 Fahrenheit. Oils are multi-grade oils.

Is 5W40 synthetic oil?

Full synthetic 5W-40 motor oil is formulated to flow like 5 Weight oil from a cold start in winter temperatures and like 40 Weight oil once the engine has reached its normal operating temperature.

Is 5W20 good for high mileage?

Designed for high mileage vehicles

Mobil 1 High Mileage 5W-20 motor oil is recommended by ExxonMobil for use in high mileage vehicles (even those that have used lower quality conventional oils), including: Cars. Trucks.

What cars use 5W20?

For model year 2001 and Newer: Ford, Honda, Chrysler and other OEM’s specify 5W-20 and 0W-20 motor oil for most all cars and light trucks.

What temperature is 5W20 oil good for?

5W-20 is a comparatively thicker viscosity oil and is better for a normal operating temperature range of -22°F to 68°F.

What happens if you use 5w20 instead of 5w30?

If you are using 5w20 instead of 5w30, you should be careful. The 5W20 is thinner and colder than the 5W10. The use of 5w20 in warmer temperatures may result in more friction and faster engine wear, as opposed to 5w30 in cooler temperatures. It will eventually affect your engine’s performance and life expectancy.
