In my opinion the best diesel engine additive
Although expensive I feel it’s the best bang for your buck. I can works perfectly for my RV fuel tank. I’ve noticed a smoother running engine and trust it with my rig. Recommend

Quiet idle and smooth starts on the old 7.3
Tried another brand of fuel treatment to help add some lubrication to the injectors. I could never tell the difference to be honest, and the bottle it came with was terrible. After some further research I found the laboratory tests comparing this product to everything from competitors to ATF and 2-cycle oil. After giving it a try, I am very pleased. My 97 7.3 with 140k miles ran noticeably quieter right away. Been running it for 5k miles and will be buying a larger refill for my next round.
