i didnt put it in the oil, people say you should do a oil change 24 hours just incase, i wouldnt want all the crud it get to clog the oil filter and seize the engine lol
youll need a busy to keep your car revved at 2000rpms-2500rpms or it will stall instantly. and dont let the vacuum line suck huge gulps of it or youll fould a plug. cover the opening of the bottle with your thumb and let it dribble out and let the vacuum line suck it up lil by lil
good luck!
