Can I Use 5W 40 Oil Instead Of 5W20?

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. The turbo also needs synthetic oils to withstand the heat of the turbo.

What kind of oil can I substitute for 5w20?

Our answer: In most cases, 0W-20 is a perfectly acceptable substitute for 5W-20. Both products are 20-weight motor oils at operating temperatures. However, the exception to using 0W-20 in your case may be if the vehicle is under warranty (see more below).

What is the difference between 5w20 and 5w40?

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 put 5w-40 oil in my car?

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

Can I put 5w 30 in my car if it calls for 5w 20?

In general, it is not recommended that you use 5w30 oil (or any other oil weight) in place of 5w20 oil, as the slightest difference in viscosity can potentially damage your engine.

Will the wrong oil damage my engine?

Cause damage to engine life
The wrong engine oil can cause engine damage because it does not properly lubricate its components. This will lead to metal-on-metal contact since the moving parts are not being lubricated. Friction quickly follows, causing engine parts to wear.

What happens if you put the wrong weight oil in your car?

The brand of motor oil matters little, but its viscosity grade (10W-30, for example) is important. Use only what the owner’s manual specifies. Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so.

Will 5w40 increase oil pressure?

However, as it warms up, the 40 oil will get thicker and more viscous relative to the 30. This will, increase oil pressure and the work that oil pump has to do.

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.

Do high mileage cars need thicker oil?

Yes, high mileage cars need thicker oil. If you’re putting high miles on your car, your engine is subject to more wear and tear. Using thicker oil helps keep your engine parts lubricated for longer and keeps your engine in great shape.

What causes engine oil to black?

Why Is Motor Oil Black? Thick, very dark, or black engine oil usually indicates that your oil has been exposed to dirt or dust contaminants that lead to a soot build-up. Direct injection gasoline engines produce soot over time that causes standard motor oil to turn black and thick.
