My great uncle used to add transmission fluid to the gas tank, because he thought it cleaned the carb & engine. So it seemed to me that it would work in the oil bath. From now on maybe I'll add regular motor oil instead.

Probably would clean the valve train components nicely but dont do it with newer vehicles with a O2 sensor, it would kill it in no time.
