Our first f-250 had over 300,000 miles with an untouched 7.3 motor. Our current f-250 has 220,000 miles, 2001, 7.3 again with an untouched motor. This is the only additive we have used in almost 30 years.
Bottom Line
Yes, I would recommend this to a friend.

Have used this for years in diesel pickups (RAM Cummins), as well as Volkswagen diesels. Added at each fill-up. Kept everything running smoothly and clean. Just bought a diesel motorhome. That's next!
