Any of you guys tried the Rotella DFA fuel additive? I just bought a 96oz bottle from Waly World today and was going to give it a shot. It was 12 bucks for 96oz's and it will treat 300 gallons thats 8 tanks for the dodge. I was just curious if this stuff is as good as Power Service or if I F-ed up and should have bought my old faithful PS.
