i think this is one of the
only miricle in a bottles that i would back up.
i had dirty injectors, and techron couldnt clean em, and i didnt want to drop $80 for the service, so i used 1/3-half a bottle and they were cleaned in less than 50 miles.
i did use it in my brothers fiero gt and there was a huge cloud of smoke, just wondering, if i didnt add it to the oil, should i still change the oil?
