Willyb, I have read the fine print on a lot of the octane boosters. Most of them will say they will make 2 or 3 tenths of a percent increase in octane boost. If takes 1% to go from say 89.1 to 89.2 then really the 2 or 3 tenths of a percent is actually 2 to 3 100th of an octane. I used to use Rocket Fuel when I had my built 80" Evo which had static compression of 210lbs per cylinder, but it would still ping unless I used 100 octane pump gas. I don't have that engine anymore,and I am glad because the places that sell 100 octane are few and far between not to mention the price. Also I remember that if I didn't have a pretty much empty tank and mixed say 92 Octane with 100 Octane it didn't work as good. But if I could get a full tank of 100 octane you could really feel the difference. You could hear it in the exhaust and no pinging. I now think octane boosters are a waste of money and as one of the other guys said what you are paying per gallon at the price they charge for a small bottle is outrageous.Probably cheaperer to buy 100 Octane if you could find it. Most small airports will have it.) Just my 2 cents based on experience. Another snake oil I avoid is fuel injector cleaner additive. At most they will loosen up some debri that will then get stuck in one of your injectors.(Sorry for the slight subject change) CAHDBIKER
