my car has 280000 miles i just did a full sea foam treatment, in my gas, in my oil, sucked it up through the IM, everything. no problems, runs ALOT better. its only good to have that if your motor is beat up inside, guess mines not. no leaks or smoking from my car since then (except for when i burnt out all the sea foam)
