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.

Less Friction = Cool Running = Long Life

Many years ago, and old farmer told me about a test that an oil distributor ran on his farm using synthetic oil in one harvester and conventional oil in another. It proved to him that synthetic oil was better by far. I switched my Ford 7.3 liter diesel to this Rotella T6 at my next oi change and have used nothing but this ever since. That Ford is pushing 400,000 miles now and still going strong.
