VP Racing Fuels 29505, Madditive Octanium Unleaded Octane Booster - Quart (Pack of 1)

Butt dyno feels like it provides my 5.0 Mustang with 40 or so more HP. Definitely more eager to accelerate faster as RPMs climb faster, I use 1.5 cans per fill to reach 108 octane when added to the 93 octane in my full tank.

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.

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

Excellent product

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

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.

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

BT Moto had a Stage II for my ZH2. With the additive I could get the Second Stage giving me 240 HP at the wheel. Bike is super fast and torque for days.

Great!

قمت بتجربه نص العلبه على تقريباً 15لتر بنزين 95 وفي العلبه يقلون تكفي 38 لتر او 10 جوالين جربت قبل اضافه المحلول هاذا وجربت بعد اضافه المحلول يعني جربت في وقت واحد الصدمه كان التسارع الاول افضل ب 2 ثواني يعني لا تضيع فلوسك والله مافرق ابداً مبلغ كبير في شي مايستاهل والله والله اعلم اذا كان مغشوش او لا. التجربه على كامري V6 ( لاتضيع فلوسك )

It's very good octane unleaded, and you can use in stock car no problem

Very good

Does what is says. Use it in my 2stroke dirt bikes and performance is there.
