VP Racing29505, Octanium Unleaded Octane Booster - Quart

All I can say is this stuff really works. I have Nissan Skyline R33 and I put 93 octane gas in my car. With this stuff I can raise my octane up to 7 points which gets me at 100 octane or very close. As soon as I step on the accelerator I can feel the difference getting an instant increased in horse power because of the higher octane. I love this stuff it really works.

Excellent product

Kenne Bell Supercharged 5.0 Fox body was detonating on 93 octane. I could have dialed back the timing or boost level. Nah, not how I roll. Added this to a tank and took care of the issue. I add it every time I fill up. Not cheap, but horsepower never is.

Best price I could find was on Amazon mileage increased a little but under full throttle the engine seem to labor less when using this product, because of the onset of winter and summer blend gases I don't think there's a big difference between the grades anymore whether you use premium or regular or by brand for that matter

Will treat 10-gallons of fuel, making 95 octane plus possible and truck runs great.

With all the 💩gasoline available to the public my car was what we used to call spark knock, not a engine miss but poor performance and ponging under slight acceleration. I took a chance on the VP Adative I poored it in before refueling w/ the usual 93octane which is what my 06 G-35 Sport Coupe MT-6 the minute I drove 2-3 miles the spark knock / engine ping completely went away and the car performance feels great and seems to have resolved my issue. So yes great product and if you're suffering from the same issues I was experiencing then I would very highly recommend this specialty product.Gino B

Ordered was promptly shipped. Cost for the item was very reasonable.

I have a gen 2 Coyote that will add timing when it see more octane! Guess this is false advertising...
