Any from the list, top 10.Whats the best fuel additive for the 2006 6.6 duramax?
Thanks guys. The bottle says it's SAFE for diesels! I use it in my motorcycle over the winter and also in the lawn mower. I thought it would work.The study that was provide will give you some good information. For me, I have tried stanadyne, Racor, FPPF, Diesel Kleen AMSOIL and others. I have gotten the best results from AMSOIL Fuel Concentrate and their Cetane Booster.
I would not use seafoam or any product containing alcohol. Alcohol dries things out, something you don't want in a fuel system, especially in the injectors.
If I can answer any questions about AMSOIL products, please let me know.
