So I ran ATF in my tank of my deleted 6.7 and so far love it. It's idling sooo smooth. And the. It or itself is quieter. Even notice less smoke. The black smoke due to being tuned is almost cut in half.
Just started. Using just regular Walmart brand. No need to go expensive. I know people that use used ATF. But I just use the cheap crap. That way I know nothing bad is in it. A lot of people say use 2 liters per tank. But I only use one. As ATF was designed Not to burn well I don't want to overdue it. But it seems to work well. In my 6.0 I did that for 300k and still on factory injectors and fuel pump. So it has to do some sort of good. I just didn't run in in this truck till I deleted it as I don't know what it would do to egr or cat or dpf system
