Fuels 29505 Octanium Unleaded Octane Booster - Quart (8 Pack)

My SUV doesn't like regular fuel. The manufacturer says premium isn't required—only recommended. It doesn't change how the vehicle drives, but the dashboard lights up like a game show. With the current price of premium fuel, I fill up with regular and add about a 5-ounce dose of this product. The SUV doesn't seem to notice the difference. The boost costs about $4, while the difference between regular and premium is around $13 per tank. That puts about $9 back in my pocket every fill-up, and my SUV doesn't seem to notice the difference. It works perfectly!

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.

Use this with 93 when shooting nitrous just to make sure my octane stays high.

Second time buying this. It’s worth it

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

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.

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

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

Notice a big difference in 383 stroked with cheaper fuel
