FAQ:
Q: What is the difference between 15w40 and 5w40?
A: The primary difference between a 5W40 and a 15W40 oil is the cold temperature performance. At operating temperatures, theoretically BOTH oils perform the same. The advantage of the 5W is upon startup. Bottom line is 5W40 gets to the nooks and crannies faster than 15W40.
Q: What is the meaning of the 15w40 engine oil?
A: A 15W40 engine oil is a multi-grade oil, it is governed by standard SAE J300 specifically for engine oil or motor oil. A 15W or 40W oil means it has a certain viscosity as mentioned in SAE J306 (standard for single grade oil or gearbox oil), more weight or ‘W’, more viscosity.
Q: What is meant by 15w40 for generator?
A: For a gas generator, most people use plain SAE 30 because they don’t ever run in cold weather (below freezing) and SAE 30 is optimum for warmer weather (per the Onan Handbook). 10W30 or 15W40 is optimum if you want to cover sub-freezing temperature operation as well.
Q: What is the best motor oil for a diesel engine?
A: One of the most popular and best synthetic oils for diesel engines is Mobil1, famous for its spectacular protection in all working conditions. It’s unique and balanced formula keeps your engine running like new.
