Can I use 20w50 instead of 15W-40?

Can I use 20w50 instead of 15W-40?

20W-50 motor oil is for vehicles with gasoline engines. 15W-40 oil is for diesel applications. The difference between the two grades are just the specifications and for all practical purposes, in older vehicles without variable valve timing, the two grades of oil are interchangeable.

Which is better 15w50 or 20w50?

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 15W-40 oil good for diesel engines?

ADVANTAGE 15W-40 HEAVY DUTY DIESEL ENGINE OIL can be used with complete success in over-the-road diesel trucks, off-highway diesel equipment, farm tractors, and passenger cars and light trucks with diesel, turbo-charged diesel engines, or gasoline engines and is backward compatible with previous API Oil Categories.

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.

What is the difference between 15W-40 and 20W 40?

Originally Answered: What is the difference between 15w 40 and 20w 40? 40 is viscosity at 100°C , that means both have around same viscosity at 100°C but viscosity of 15w40 at 40°C is at 109 and 20w40 at 40°C has 121, 20w40 is thicker than 15w40 and and it is not recommended for cold climates.

When should I use 15W-50 oil?

15W-50 has historically been a viscosity recommended for high performance engines, and is used today primarily in motorsports racing where engines are stressed due to high revving and heat.

What is the best oil to use in a diesel engine?

If you’re looking for the best oil for your diesel engine, you can’t go wrong with synthetic oil. Synthetic oil is designed to withstand extreme temperatures and conditions, making it ideal for use in diesel engines. It also provides superior protection against wear and tear, helping to extend the life of your engine.

How cold is 15W-40 good for?

“Its starting temperature range is down to minus 22 F (compared with 15-plus with 15W40) up to 122 degrees F (same as 15W40). That tells you a couple things: There’s a 37-degree cold cranking advantage (from minus 22 to plus 15) to a 5W40 and the same benefit on the high end.”

Can you put 20W-50 in a diesel engine?

Mobil Delvac Super 20W-50 is recommended by ExxonMobil for use in the most severe applications of modern on- and off-highway diesel engines.
