VP Racing Fuels 2855 Octanium Octane Booster Racing Formula - Quart (8 Pack)

Used this in my big block mustang and my 71 Maverick. Improved performance, no pre detonation issues and improved fuel economy.

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 !!!

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

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

Fast shipment price is high for gear oil nothing special.

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 merged onto the highway behind a vehicle that was doing less than minimum allowable speed and got into the second lane only to observe a vehicle closing in rapidly. i got on the throttle to keep from getting rear-ended, still in second gear and the tires broke loose under hard acceleration. I shifted into 3rd (65mph) and avoided a rear ender and maybe a road rage incident. My vehicle is a GT500. I put a can in my Crown Vic P.I.and eliminated intermittant engine stumbling (cleaned the pipes out)!!! Gonna try to keep a case of VP in my inventory. Love this stuff.
