I own a 1979 Harley Davidson super guide 1340cc with a shovel head engine. On acceleration n on hot days the bike would ping extremely load n be sluggish on throttle response. Since I started using amsoil dominator octane booster I no longer have an issue. No more pinging n throttle response is awesome. Thanks for such a great product.

Very effective product

At first i was scepticle about the octane rating, bought the product, bought the octane test strips and yes it brings the numbers up 💯 percent!

Great price Quick Delivery and is working great 👍

I purchased three products from AMSOIL, The Upper Cylinder Lubricant Corrosion Inhibitor, The DOMINATOR® Octane Boost, and The P.i.® Performance Improver Gasoline Additive I added all three to a full tank but, prior to doing this, I had filled the tank with Top Tier Fuel for this test Shortly after I took a ride, at first, I noticed nothing, but the very next day I put twenty miles on her, and that is when I noticed she ran quieter, and that the pick-up was back I highly recommend this product for older vehicles, and I want you to know, that these products are not a gimmick Check it out for yourself

Using this product sparingly, has increased my power and mileage.

You can feel the power the vehicle loves it

Added to my mid grade gas i use at local station, its like running 94 octane fuel at half the price.

I use this in my Arctic Cat 1100 snowmobile on every tank refull - just an ounce or two and the throttle response difference is noticeable!

Mixed this Booster with lower octane fuel for my vehicles and the performance is noticeable. I understand that it is for off road use, but if you use it at a lower percentage than it calls for, you get great results.

This stuff be boooooostin!!

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.
