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.

Trust based on a lifetime of use

I have used Shell Rotella for years in my semi trucks without a single internal problem. Based on my success with Rotella in the past, I decided to trust Shell Rotella T5 Synthetic Blend in my Diesel pusher motor home. As the third owner, Im not sure what type of oil the previous owners used, but the synthetic blend seemed like the best choice. I didn't notice a difference in noise, performance, or change in operating temperature but it did seem to run a bit smoother. For a couple of dollars more per gallon over the conventional oil, its worth it
