I use stanadyne fuel treatment. I would not use tranny fluid as an additive. If you are using off-highway fuel, not home heating oil, then you don't need to run any additives that you wouldn't run with on highway fuel. In fact, high sulfur fuel is better for the injection system . . .

 

NO,atf is for trannies.It will clog your nozzles.I use stanadyne,it works real well.
