Whichever is on sale that meets API specs for diesel engine oil. Your engine will last just as long using Wally World Super Tech as it will on any other. Don't let the hype of promotional material or the brand loyalty of a few to cloud your common sense. Motor oil these days, IMO, is a commodity, just like diesel fuel and sugar.

Some independent testing, choose for yourself. Remember this article is 7 years old, so additive packages could be different.

Your focus should be on the filtration, both oil and fuel. There are some really poor filters being sold that have name brands stamped on them. The Mopar filter sold in WM is a medium quality filter. Although this is an old article, the facts remain the same.
