Hello, I have been running Jet A in my 2002 7.3 for a great deal of years without any problems. I use stanadyne with every fill up to add lube to the fuel and im good to go, My only complaint is the motor oil that I change every 3k is black black do to the high surfer content in the fuel but that's why i do it at 3k and not 5k. Any way has anyone used this type of fuel in a newer diesel engine like an 6.0 or 6.7? Im assuming it would be safe to run if the engine was deleted? Would it be safe to run if the engine had all of its emissions components still attached? Im looking at getting a newer truck and I want to know which route to go. I get the fuel for no cost that's why i have been using it for so long. Your feedback would be greatly appreciated!
