Question: Can I Use 20w50 Instead Of 15w40?

Is 20w50 good for high mileage?

Considerations.

The viscosity level of engine oil 20W50 is geared toward racing engines, as opposed to high-mileage engines, that run extremely hot and need heavy load operation.

Since its viscosity is so great, it can drag down the functioning of the crankshaft, resulting in less horsepower..

What oil is best for older engines?

When you’re choosing the best oil for older cars or high mileage engines, there are several criteria you can look at.Pennzoil High Mileage Conventional Motor Oil. … Castrol GTX Part-Synthetic High Mileage. … Valvoline MaxLife High Mileage Synthetic Blend. … Mobil1 High Mileage Engine Oil. … Amsoil Premium Protection Motor Oil.More items…•

Will thicker oil damage my engine?

Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don’t transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.

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 uses 20w50 oil?

SAE 20W50 Synthetic Motor Oil. NEO SAE 20w-50 is designed for high performance engines of all kinds, and for any engine that is pushed to the limit of performance and temperature. Excellent for trailer towing in high temperatures and for racing engines, in any engine that can use this viscosity grade.

Is 20w50 good for my motorcycle?

20w50 grade oils are not energy conserving, no worries there. Any 20w50 oil will work fine, like checkers said. You don`t need to spend 10 bucks a quart on oil. Owning a motorcycle is expensive, no reason to make it more so…

Is 20w50 thicker than 10w30?

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.

Can I use 20w50 instead of 15w50?

Yes,it would not make much difference. Important thing is to get the last digit,ie 50 correct. First digits are an indication of normal temperature viscosity or in layman terms how easy it would be to start the engine. But like I said it would be fine to interchange 20w50 with 15w50.

Is it OK to use 20w50 oil?

If an engine oil has a high viscosity, this means that it is thick; a low viscosity means that it is thin. Select an engine oil with an SAE (viscosity) classification suitable for the prevailing outside temperatures. … F, and 20W50 is OK to use at ambient temperatures above 23 deg.

Which is thicker 20w50 or 10w40?

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.

Will using thicker oil stop burning?

A lot of oil-burning takes place because an engine’s piston rings are worn out, and thicker oil won’t fix that. Using thicker oil is also a particularly bad solution for modern cars. … They use low-viscosity oils that splash easily all over the moving parts of the engine to make sure they’re all lubricated.

Which oil is better 20w50 or 15w40?

A 15W40 is going to have a much better aditive package and will more then likely be less volitile! 15W40’s usualy are shear stable were most 20W50 shear badly some down to a 30Wt.! If you want a good 15W40 Delo 400 and Delvac 1300 are the easiest to find and have excellent formulas.

Can I use 10w40 instead of 20w50?

As per Z32 fsm,10W40-20W50 is recommended if the car is driven fast,raced,or in driven in hot climates,and 10W30 is recommended for fuel economy only.

When should I use 20w50 oil?

20W50 motor oil is suitable for warmer climates, where the higher temperature causes the oil to thin. It is also useful for vehicles subject to hot temperatures and for those used for high-stress activities such as hauling or pulling trailers.

Is 20w50 thicker than 30w?

20w50 will be thinner when it is cold but at a 100 degrees it will be thicker than a 30 wieght.
