AnswerI have used Gumout Octane Booster for about 6 months now. I drive an '89 Ford Ranger. Before the booster, it would knock and ping at the bottom of lower gears. It would stall whenever it felt like it. About 10 miles into the first tank of booster, I noticed a dramatic improvement. Hesitation is lower, no more stalling and idle is smooth. No more knocks and pings. It costs me under $2 per bottle. I use 1 for every tank of gas and I went from 17 to 24 MPG. That is not an exaggeration. I tally the MPG at EVERY fill-up. AnswerYes, they work to an extent. But, let it be known, if you are looking for a "magic bullet" to fix knocks and pings, I would look elsewhere. You could have a more serious problem somewhere within your engine causing the knock. If an Octane Booster "solves" your problem (knock/pinging) - then definitely take your car to a decent mechanic for further diagnosis.

Also, consider, a growing number of vehicles on the road today actually "require" or "recommend" higher octane fuels. Check your vehicle's owner manual. It may be possible you've been using "Regular" unleaded, but you should actually be used "Mid Grade" or Supreme gasoline. So yea, if this is the case (your car requires Mid Grade gasoline, but you've been using only regular) - that could be the source of the knock and ping you experience.

Gumout Octane Booster contains mostly JP5, which is used in the US Navy as fuel for aircraft, and really cleans fuel systems well. The improvement you felt was most likely a cleaner fuel system as well as cleaner injectors.
