Fuel Additive for 2012 6.7 Cummins
I have been reading the threads and most of them pertain to older diesel trucks. I just bought a new 2012 6.7L Dodge 2500 yesterday and hope to have years of fun with it. All of the threads seem to agree that an additive is needed with every tank of diesel. So I decided when I picked up my truck to talk to the head diesel mechanic at Dodge. He said that the new Dodges were built to run on the ultra low sulfer diesel fuel and no additive is required. He even went so far as to say that many of the additives could actually harm the engine or make it work harder to remove the buildup that the additives can cause. This is my first diesle vehicle so the contradicting points of view are very confusing. Yes or No to additives?
