The fact that it helps with reducing the water condensation in the gas tank and makes the fuel burn completely was my trigger of interest cause living in a state that it's cold for 9 months and then learning from the Jay Leno video about the fuel treatment, I was sold.
Great results for my diesel no Improvement V8
My old Ford 4100 tractor runs like new and more power than before.
used it on my trans am that sits for more than 6 months. Retired starts and ran ok .using it to keep injectors clean . hard to tell , it always ran good . Don't see any difference.
I’ve been using it for years. Always dose what it says it will do. I wouldn’t use anything else.
