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

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

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 .

A good buy

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

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.

I use this in my 2016 GT Mustang with a 2.9 supercharger and tuned by Lund Racing. Gives the gas I use around 101 for octane and is a better price then my local auto parts store.

The additive works. They showed up in old cans and every single can was dented and beat up. I'll continue to buy from someone else.
