Review: Very easy to use - Great fuel injector cleaner
Review: Necessary tool for working on modern cars! - Works exactly as I thought it would. Did a nice job cleaning injectors, the flow test proves the results. I was a little baffled as to what testing solution to use. Instructions say DO NOT use cleaning solution, gas, diesel, etc but never says what to use. I finally saw a video using medical alcohol so that's what I use. When mine arrived it would not build pressure to flow injectors. I contacted seller, they replied next day with instructions on how to fix. Took about 5 minutes and back in business. So excellent customer service!
