Fuels 2857 Octanium Octane Booster Case (256 fl. Oz)

This makes my Big Twin purr like a kitten . Smoothed out the idle and increased power and gas milage . I have used this additive for years with great results .

Honestly the best octane booster ive ever found. Its a lil expensive but thats a sign that it actually works. Have used this product in my racecar and my SxS !!!

Fast shipment price is high for gear oil nothing special.

works for what i need, gives that little extra zip to hightest gas. i can drive my race motor on street.

A good buy

I usually fill my tank with regular unleaded and once in a while, supreme unleaded. I can't discern any performance difference in my car between filling up the tank with the two different unleaded octanes. Sometimes I regret not buying a higher performance car, but I like the mileage and the performance is acceptable but not great. Once I filled the car with supreme unleaded and added the VP Racing Fuel's octane booster. There was a notable difference in throttle response. With supreme unleaded and the octane booster I can get the quicker acceleration for 'fun' driving every once in a while to get it out of my system.

Oh, to fill up with 93 premium gas is around $60'; then add a can of this super fuel....it bumps up the octane and yes, my 911-4S Porsche screams....this fuel additive simply gives my car a kick in the pants....I dont think it makes it any quicker...but this stuff just makes the motor hum and respond instantaneously .... I bought a case of the stuff and from time to time, put a can in with a fresh tank of gas....It's not JP-4 Jet Fuel; but it does put a little more zip in acceleration...expensive to add to a full tank of 93 octane, but I feel it gets a little more out of the response.

AOK
