Anyone ever use this in their diesel trucks ?

We used to use it in our cars, trucks,(diesel & gas) and boats as a fuel condtitioner and stabilzer when we lived up north. Works very well for this application.

I've used it as a fuel stabilizer

I often use it in the gas tank as a fuel injector cleaner. Has never failed me yet. Great stuff.

Thanks for the replies, been thinking about putting it in my diesel.
