A single bottle of octane booster will not take a tank from 87 to anywhere near 92. Read the back of the bottle carefully to see how much you need to add to get the number printed on the front. I've seen 20%. Four gallons of fuel, one gallon of booster. How much does one gallon of octane boost cost?
