how much milage have you gained?:rofI add 10oz Diesel Kleen to every fill up. It will pay for its self with better fuel milage. If it cleans and protects as advertised I don't see how you can go wrong. I've heard that the Amsoil is great also but haven't used it yet.
Can you switch to a diesel kleen that already contains the anti-gel additive or do you switch products all together?I get about a 45-50 mile range increase. I've heard that switching to synthetic oil increases fuel milage even more. Staying off the skinny pedal is the best, but how much fun is that? Its almost time here in NY to switch to additives with anti gel. Its in the 40's already!
I believe it helps. I have been using it since I bought my truck. It starts better and combined with the AMSOIL fuel concentrate, my fuel economy has improved. Cetane booster is designed to help with fuel ignition quality and reliability.Does cetaine boost help out a whole lot? I ask because I am getting ready to make an Amsoil order and if it's worth it I will get some but If not I'll hold off.
