I gain 1mg but I’m getting more power and less rpm. Love this product.
Truck seems to start a bit quicker now. It runs quieter and a fuel additive is a must have for on highway diesel. I’m running it in a 2006 6.0 and very happy with it.
quiets motor some, runs cooler, and seeing improved mileage, second oil change I've used it on Ford 6.0 Diesel
Engine runs cooler, more quiet instantly picked up about four miles per gallon. Thanks for the customer for life my 2007 6.0 F-350 loves it!!
2002 Ford Excursion 7.3 that moved from Texas to Alaska two years ago. In the south the friction modifier and fuel treatment were nice but I would sometimes let it slide as I tested other products over the years. The combination is fantastic in cooler weather. The truck starts better, runs quieter, and gets better mileage.I just discovered the Archoil Winter treatment and look forward to using it this winter.
