Now this octane booster. Whoa. This stuff does work miracles. The power. The boost, I mean, you can't beat it. Another great product of Amsoil. And I love it. You guys need to try it.

My Genesis GV70 is turbocharged and requires above standard octane fuel lest the computer backs down the settings and thus performance. Problem gone when using Octane Boost. And my fuel economy increased between 6-10 percent as well. I'll keep using Octane Boost

A must for any Corvette that runs on premium pump gas! Huge difference in performance.

This product far exceeded my beliefs in fuel additives. 💯. Love it

Massive Hp Gains for any high performance vehicle. Increased fuel mileage as a bonus. Well worth the money. The car is extremely happy, and runs really strong. I highly recommend this product!!! Your car or truck will thank you.

Love all the products

The Softronic tune on my Porsche likes 93 octane, but around here it is hard to find anything over 91. This gets the job done and then some with one bottle per tank.

I added about 1.5 ounce of Octane Boost to about 10 gallons of last year's gas when I pulled my 4 stroke snowmobile out of storage. It had previously been dosed with about 4 oz of gas preservative/stabilized added when it went into storage. It ran great on my first ride.

Occasionally I will give my truck a treat, every couple of months I'll put a tank of 93 octane, where I normally put mid-grade I like to think that using the higher octane will keep things a bit cleaner. When I do this I will try to put one of these "Octane Boost" into the tank with the 93. I can feel a difference when I accelerate and knowing that I am using quality fluids from AMSOil I know my little truck (2016 Ram Power Wagon) is well taken care of.

Amsoil Products to me #1

I've been using Amsoil lubricants for almost 10 years. I started using their octane boost a few years ago in my 2011 Raptor when off roading and it give me that extra power when i need it most.

Best

After receiving this advertised product performance additive, I tried it. I am happy to say it actually provided substantial performance; you could feel it. In my opinion, the product price could be better. It is a little overpriced and should cost customers less, thus causing better social awareness of this good product.

Real "feel" the difference on the performance of the engine and smiles on your face!

Works great,noticed a big difference in performance.

5 stars for the engineer(s) that developed this concoction! It increases the "Smiles Per Mile", as well as the throttle response in my LS2 powered 5th Gen. GTO. I add a bottle of Octane Boost every track day I attend, and whenever I want to impress friends that occasionally get to ride in my hotrod!

I used this product 1st with my Caddy ATS and when I I tell you she really hauled booty when I would use it, I’m being dead serious. Octane Boost does the same for my CTS-V so until I get my flex fuel kit I’ll be turning to Octane Boost when I want to move a little quicker.

As always, this tuff really works, and I keep several bottles in the vehicle in case I am forced to use a lower octane fuel.

I’ll try it after new engine is broke in when I could get a little more use with it.

My old dodge with a tired old 318 is spinning wheels and pering like a kitten
