My experience with ATF in fuel tank
I have heard of people running a quart of ATF in the fuel tank at each fill up, and I just happen to have a ton of ATF laying around. My neighbor guy told me he has done it a few times in diesel and in gas engines, he says people do it to clean the fuel system (detergent in ATF).
I have been running a quart of ATF in my fuel tank since about the last 6 - 7 tanks, and I can say it has made an improvement in my particular case. I used to have some injector stiction issues when EVERY TIME I first cranked up the truck in the morning, and it would go away on it's own once warmed to operating temp. Since the ATF I have noticed that now when there is an occasional issue with stiction it goes away after about 3 to 5 seconds of the truck running.
So in my personal experience it has worked for me, and I am continuing to run the ATF in there now (because I still have about 3 - 4 quarts extra anyway) Truck has 142K on it, and as far as I know original injectors. Also note this trick doesn't work after the first tank, took me until about tank number 3 - 4 i think to notice the stiction was basically gone.
