SMB Octane Booster
Our car "check engine" light began coming on when we first bought it in 2008 and my husband said to put in an Octane booster. I decided to try SMB Performance Booster and, Bravo!!! It works beautifully. And so inexpensive!! No more lights coming on!! We use a 12 oz bottle for every 11 gallons.Thank you for making it an affordable booster for folks who are on social security!!

Great Octane Boost
This octane boost is a good deal and works very well. I have a 1990 Ford Ranger with 370,000 miles on it's 2.3 liter 4 cylinder engine. Without using a good gas treatment and or octane boost the engine knocks and runs a bit rough. Using one third to half bottle per 5 gals. of gasoline of SMB Octane Booster ENDED the emgine knocks and gave stronger and smoother acceleration even while using the new inferior quality ethanol gasolines which had made my truck run rough and poorly. This product also works well when added in combination with other gas treatments at the same time for even better effects. Please keep making this product available---esp. at $1.00 / bottle.
