The amsoil Product is outstanding as well as standyne. Diesel clean works very well to and you can buy it at wally world.
There are very few companies that actually make there own addative. Standyne, Powerservice, amsoil, lucas are a couple. most everything else is co-packed by one of the above companies.
I currently sell the Amsoil and standyne addatives. Been talking to RBP and may start carrying his product aswell.
