Rated 4.9 out of 5 by 10 reviewers.
Rated 5 out of 5 by Very good product Toyota 1987, Pick up 4x4, 400,000 miles and original fuel injectors. At 300,000 a slight miss that could not be corrected with a tune up valve adjustment, O2 Sensor replacement. The miss was removed with 1 can this cleaner. I use it every 10,000 miles and the truck is running fine July 28, 2015
