I have 1 qt ATF put in the fuel tank of all my Powerstrokes every oil change. Usually tank is fairly low around a quarter. I my mind it helps keep injectors clean. Some have over 400K on them since I have started the practice. Lube shop was using filtered diesel or ATF on the 8V92. They have had a personnel change so next service is a freebie at Stewart & Stevenson so not sure what they will do.
