Review: I use these in my diesel generator, and the results have been great. It’s reduced soot buildup, made cold starts much easier, and gives me real peace of mind knowing my generator will run longer with fewer issues down the road. Excellent product — definitely worth it if you want to extend the life and reliability of your diesel engine.
Review: A must have kit for all 6.0 owners. This stuff is liquid gold. When I first bought my truck it had the typical stiction issues and fuel system/turbo issues that 6.0 liters have. After using these products only once, it removed the stiction problem, cleaned my turbo and improved my fuel economy. I went from 3.8 km/litre to 6.2 using it as a daily driver, and on a long trip, got 7.3 km/liter. Outstanding!! I use this at every oil change. Worth every penny :o)
