This is the only oil I will use in my diesel engine. I've built a lot of engines and know how they perform and last on this oil.

You cant ask for a better conventional oil. Recommended by Cummins to keep your factory warranty with the new 2019 Cummins engine

Hard to find in stores. Used this for my Diesel Ram 2500. I live in Florida so I choose the 10W30. Arrived on time and in great condition.
