About 20 years ago someone told me about mixing ATF into their fuel to clean out the fuel system.
They did this on both their gas engine and diesel cars and reported good results.
This made sense to me, since it was one of the 3 "cleaners" we used to use in the auto shop to clean out cylinders (the other two being diesel fuel and water. All poured very slowly into the carburetor with the throttle held wide open. Only use one of three, not all 3 at once).
Anyway, I tried this in my gas powered truck. I added one bottle of ATF (I used the generic brand offered at Walmart, since it was the cheapest I could find) to a full tank of gas (14.8 gallons).
Worked great. My truck hadn't run that good in years...however, it only worked the first time, and that made sense too. Once you get the cylinders clean, you can't really "re-clean" them. However, maybe an occassionial application, in order to keep things clean would help (of course, so would allowing the engine to run long enough to properly heat up, then cool down, like its supposed to, rather than just running it cold on almost a daily basis like I had been at the time).
Anyway, I'll leave you the choice of whether you want to try this or not, but in my case, it did work.
It was only a couple of bucks, and the only work I put into it was to go out and buy the ATF, then pour it into the tank.
