I too, am curious about this stuff. When I was in high school I worked part
time at a gas station. The station owner used to laugh at the people he sold
this stuff to, claiming it was nothing more than automatic transmission fluid
at 3 or 4 times the price. It even looks like auto trans fluid. But, I've
seen several folks on this list who swear by the stuff. For the record, I'm a
believer in TufOil.     Jeff S.
