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.

Best oil

I've been using this oil for my 2500 diesel truck for the last four years and I put 4 to 6000 miles between oil changes and the used oil looks like the same color when I put it in new. Full synthetic. 15W 40 Rotella. I use oil filters for synthetic oil . Keeps truck working great !
