Ok so i put it throught the pcv valve, the engine is warm as directed on the bottle. Pour about 1/2 the bottle slowly, let it sit for 15min turn it on and nothing! not even a fart! what gives??? this crap sux! i doubt my engine is carbon free after 69k miles



I don't know, maybe it was already done recently before I bought it or it is really clean already?
