Is Rotella T5 15w40 refined from natural gas?

Yes - Pennzoil and other use a refining process called GTL (Gas-to-Liquid) to produce Group III base oils that are the primary ingredient in modern engine oil.

Is this what I use for my 2020 ram tradesman diesel?

Our 5th gen Rams with the 6.7 Cummins ONLY use either 5w40 (if average ambient temperature is below 0F or 10w30 for average ambient temperatures above 0F. Our 5th gens have a different oil system and do NOT use 15w40

Despite api ck-4 on the image of thelabel, i received api cj-4 product when i ordered gallon packages in jan 2018. will i now get api ck-4 product?

If you aren’t satisfied with cj-4 product, you can always return it back and request for Ck-4 to be send to you. After all, this is an excellent oil product for all types of engines including portable electric generators.
