There has been plenty of discussion about adding 2 cycle oil to your fuel so lets not get into that. What I wanted to ask is if anyone has ever heard of adding Automatic Transmission Fluid to your fuel. The lead mechanic for our local city shops says he adds 1 quart of ATF to a tank of diesel fuel every so often to every diesel truck in his fleet and that he specifically adds ATF if a truck is running rough. He claims the detergents in the ATF clear the carbon out and help the truck run better/smoother.

I'm going to run 2 cycle in my next full tank but thought I would ask if any one has heard of this or has any thoughts?

 

There has been 10X more discussion about burning ATF than 2-stroke oil. Read until your eyes bleed. ATF is made NOT to burn.

Sorry--I tried searching but I guess I got to technical. Simply searching for ATF would have gotten me an answer without bothering anyone else.

Thanks.

 

Just add some biodiesel.
