Default Re: Marvelous Mystery Oil?

I had a buddy, a retired gentleman who was a B-17 pilot back in the day, who used to swear he put a quart of ATF in the gas tank of all his cars every so often. I think MMO is the same deal. I know ATF is a great penetrating oil so it couldn't hurt -- too much -- could it? His cars always ran well. He's been gone from us a while now, but I know he had cars with fuel injection and catalytic converters. Probably not OBD-III though, or whatever it's called now. My '03 GMC popped a Check Engine light the first time I had to fillup with 10%, and had to be "recalibrated." Has somebody else tried MMO or ATF in a modern?
