I had a rep from BG come to the Toyota dealership where I work. When he approached me and asked to do a test on my car which is a 2011 Scion TC with 93,000 miles, I figured it wouldn’t hurt because most cleaners and additives normally don’t do much. They ran the cleaner through my engine, let it run for 20 minutes, and put the 44K® in my fuel system. After they changed my oil and added the MOA®, I took my car for a little test drive at lunch and instantly could tell a difference. It pulled out like it did when I first got it and it would run like a new engine. I’m very happy the rep asked me to do it on my car and I’m amazed by the results. Would suggest it to any one and all my friends in a heartbeat!
