I'm glad someone else posted about ATF (Automatic Transmission Fluid). Marvel Mystery Oil is really no mystery at all. It's a good grade of ATF. The previous post about ATF is correct. I have witnessed it work on an old Post Office Jeep (232 or 256 straight 6 AMC engine, I can't remember which one)with horribly stuck rings. An old timer saw me struggling with the vehicle and he took it for a couple days. When it came back it ran beautifully. All he did was drain ALL the oil and replace it with ATF and pour a couple quarts in the gas tank as well. After driving it for 50 or 100 miles he drained out the ATF and replaced it with oil. No more smoking, no more burning oil, no more gas contaminating the oil.
