I run this in every motor I own, 3 TDI engines, outboard, Armada, 73 ford f350, lawn mower. have been doing so for 8 years.

If you run a diesel the only way to go is Rotrella-15/40 T6 The very best in oil.You will not be sorry!

This oil works hard to protect my 24-year-old 7.3 liter Ford diesel. Almost 350,000 miles and still going strong.
