Trans fluid, will burn and it burns white hot, on top of the pistons, but if you didnt add to much , and have a full tank of gas it shouldnt hurt a thing, it will clean the injecters , and burn off any carbon build up , and might make another horsepower or 2 for awhile, but dont think id worry about it, truck drivers use this in there engines all the time, to clean out their fuel systems, diesil motors run good on this, in small amounts, like a quart to 50 gallons, so a little bottle in the gas wont hurt
