Which is better 20w50 or 10W30?

Which is better 20w50 or 10W30?

Designations on the label — such as 10W30 or 20W50 — tell the oil’s viscosity. In the owner’s manual, car manufacturers recommend oils for the brand new vehicle, and 10W30 is commonly used in new engines instead of heavier oils. So, 10W30 oil has less viscosity (flows easier) when cold and hot than does 20W50.

Can I run 20w50 instead of 10W30?

The main reason for using 20w50 is to slow down oil burning. If this is the case, using 10w30 would speed up the burning. I have had oil burners before, and used 20w50 in the summer, with no problem. But, your car will be hard to start in very cold weather with 20w50.

What is 20W-50 oil used for?

20W-50 is a common motor oil used in moderate-to-large diesel and gasoline engines, high-performance motorcycle bikes, and aviation vehicles. Its resistance to thinning at high heat also makes it popular as a racing oil and high temperature driving.

Which is better 10w30 or 20w40?

20w40 is thicker at high temperatures than 10w30 It is desirable for lubrication at operating temperatures to be high. 20w40 is better than 10w30 at normal operating conditions.

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.

Which is better 10W40 or 20W50?

The smaller number, (the 20 part of 20w-50) describes how the oil behaves at 40 deg C and a 20w at 40 deg C is about 10 times thicker than your engine wants. A 10w-40 is better at around 6 times thicker and a 0w-40 is much better at about 4 times thicker.

Is 20W 50 too thick?

The “20W” indicates how quickly the engine will start when cold or in cold weather. The “50” refers to the thickness of the oil when the motor has been running for a while. 20W50 motor oil is relatively viscous and thick. Most modern oils are 10W40 or even 5W40.

What happens if I use 20W-50 instead of 10w40?

Better built engines will have more exact tolerances and be able to run on the 10W-40 much better. If the engine really needs 20W-50 because of its design, you will harm it by not having enough film strength.

Can I use 20w50 instead of 20w40?

20W40 is suitable for hotter climates and will not cause sludge as opposed to 20w50 which is more appropriate for hotter conditions. But, it has more drawbacks than 20w40. For example, it will only pass two or three cold starts in a colder climate but nothing beyond that.

Can I use 20w50 oil instead of 5w30?

20w50 is actually thicker than 5w30. This will result in less fuel efficiency, less horsepower, and more engine damage because it will have to work harder to rotate. Trust the engineers that made your vehicle.
