Everyone may want to know this. I just bought a case of stanadyne performance formula from one of the local diesel shops because he gave me a pretty good deal on it. The thing that everyone will want to know is that according to him it will give you up to an 11 MPH increase in fuel economy LOL .. That sold me on it, I bought a whole case. LOL I couldn't believe that guy actuallly told me that in a serious tone. I can tell a difference in the motor, it actually runs smoother and quieter, but there is no increase in fuel mileage. If anyone finds an additive that doubles fuel mileage please let me know !!!! Some of the things these guys will say to sale fuel additives cracks me up.

 

is that 11 MPH or 11 MPG ?

 

I run lucas every tank and I consistently get between 1-2 mpg better than a tank without it. Sounds crazy but it's true.

 

Correct, 11 MPG

 

I now run lucas and several of my buddies have had the same results. 1-2mpg better with the Lucas.

 

11mpg wow that is some sales tactic

 

I think I would have passed on this "great deal" simply because I don't like being lied to.
