What is 15W-40 good for?

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.

Which is better 15W-40 or 5w30?

15w40 is usually used in diesel engines and has a much different additives profile. 5w30 is usually used in gasoline engines. Diesel oil is designed with high antiwear additives such a ZDDP.

Can we use 15W-40 instead of 5w40?

YES. Lowering the first number gives you much faster oil circulation on every startup, and especially in the cold. So you engine will have lower wear on every start-up. And since it flattens the viscosity curve, in hotter areas, like turbos, a 5W-40 will have more viscosity than a 15W-40.

Can I use 5w40 synthetic instead of 15W-40?

15w40 can be used in the temperature range of -20 °C or -4 °F and +40 °C or 104 °F, on the other hand, 5w40 is used between -30 °C or -22 °F and +40 °C or 104 °F. So, we can say that 15w40 is better in a warmer environment and 5w40 does a better job in a colder climate.

What is 5W40 oil used for?

5W-40 motor oil The 5W-40 viscosity is a prevalent recommendation for performance engines in European vehicles with gas-powered engines, and in American diesel pickup trucks. We offer 5W-40 oils for gasoline- and diesel-powered engines.

Can I use 15W-40 in my gas engine?

Others lean toward higher-viscosity oils to protect against wear. Some want to run a 15W-40 oil in their gas engine, and it’s often easier to find a 15W-40 or similar viscosity of diesel oil than a gasoline motor oil. Others favor the increased detergency of diesel oils.
