What is 15W-50 oil used for?
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.
Is Castrol a 15w40?
If you need a 15W-40 diesel oil, Castrol GTX helps extend engine life, protecting against the wear and tear of severe weather, rough roads and heavy tows.
Is 15W-50 thick oil?
Mobil 1 15W‐50 is a higher viscosity oil that delivers a thick oil film for protection of high‐performance engines.
What is thicker 10W 40 or 15W-50?
These viscosity index numbers are used to describe the relative thickness of oils for comparison. The 15W50 has numbers higher than the 10W40, therefore the 15W50 is thicker both at ambient winter test and engine operating temperatures.
What is the difference between 15W40 and 20w50 oil?
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. 20W-50 motor oil is for vehicles with gasoline engines. 15W-40 oil is for diesel applications.
Is 15W40 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 happens if I use 20w50 instead of 15w40?
It is best to use the same brand, type and weight of oil you put in at the last oil change. Unless you are at the fringes of temperature range for the 15w-40 oil, putting the 20w-50 in isn’t going to change the viscosity of the oil enough to damage anything.
Will 20W-50 hurt my engine?
Is 20W-50 Oil Bad For My Engine? 20W-50 is not a very popular oil viscosity. In the wrong engine, it can lead to sludge, excess friction, varnish deposits, problems with oil burning and oil pressure, and even affect your engine life.
Is 20W50 good for hot weather?
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.
