Rotella T6 is my go-to oil for motorcycles and heavy diesels, and while it's a bit pricier than other oils, I've never had an engine failure in either of those classes of vehicles. I tend to stick with what works for me. Excellent product.

Use T6 unless a T7 is available

Its T6. The best value for Diesel Oil available in a synthetic. I use in the 7.3's High pressure oil system and have not had any issues. Starting seems to be slightly better etc, but that could be due to the fuel filter change as well. Extremely satisfied as is most with T6.

15w-40 diesel engine oil

Great stuff, I started putting this in my 05 dodge ram 2500 since the first oil change after purchasing it used. Usually I run this for about 8k miles with a second oil filter change around 4k miles and no problems. Would recommend to anyone looking for a decent product for their engine, if it's compatible.
