Product Highlights View Full Description

Maximizes power and improves performance in all two-cycle and four-cycle gasoline engines. Increases octane up to 4 numbers. Reduces engine knock, improves ignition and engine response, helps fuel burn cleaner and inhibits corrosion. Recommended for off-road and racing use.

AMSOIL DOMINATOR® Octane Boost (AOB) significantly increases engine response and power in all two- and four-stroke gasoline-fueled engines by increasing octane up to four numbers. Just one treatment reduces engine knock, improves ignition and helps fuel burn cleaner. DOMINATOR Octane Boost is the recommended octane boost for all high-performance off-road and racing applications. Most users find one 12-ounce bottle of DOMINATOR Octane Boost for 15 gallons of gasoline provides the ideal performance increase. DOMINATOR Octane Boost is also excellent as a lead substitute at the same treat rates in collector automobiles, older off-road equipment and pleasure vehicles.

What is "engine knock" and why does it matter?
"Knock" is an uncontrolled and explosive ignition of a hydrocarbon fuel, such as gasoline, in the combustion chamber. It causes a knocking or pinging sound, robs the engine of power and, left unchecked, causes serious engine damage. Fuel's tendency to knock is measured by its octane number. Lower numbers denote greater knock tendency; higher numbers denote greater knock control. Knock may be eliminated with the appropriate octane number.

Comments about DOMINATOR Octane Boost:

I have used Amsoil products for over 20 years and have always been happy with the results. My recent purchase of Octane Boost has proved to be no exception.

I used it in my 2003 Harley Lowrider this weekend and honestly, the result was something that made me not want to bring the bike home. Smooth application of power especially at low RPM and just taking off. Engine ran noticeably cooler and it may sound crazy but the exhaust note was slightly different. There was more........growl to it than before. That I noticed but did not expect.

On the highway and climbing hills the increased performance was quite evident.

Now, it was not an engine overhaul, and nothing magic, but for a noticeable improvement in overall performance give Dominator Octane Boost a try. I am certain you will like the feel.

Great stuff!

Comments about DOMINATOR Octane Boost:

I use the octane boost when I want a little more performance in whatever vehicle I choose. I use it in my supercharged truck in case I can't find the minimum 93 octane it is dyno tuned for. I use it in my Screaming Eagle Stage 3+ Harley Davidson Ultra Classic Electra Glide, which is also dyno tuned for 93 octane, when it can't be found in a Smokey Mountains podunk town. I also use it in my Acura TSX on occasion. Awesome stuff!

Pump gas isn't always good enough.

By 

from Ocoee, FL

Comments about DOMINATOR Octane Boost:

Pump gas can sometimes leave more to be desired. I run 93 octane in my vehicle to get the cleanest burn that I can (despite what some articles might say). I used this product to run with the Amsoil Performance Improver P.I. fuel system cleaner to optimize my results. I have had an increase in my fuel milage as compared to before treatment (my fuel milage wasn't bad before and is now better). I recommend this product by itself or with Performance Improver P.I..

Keep a stash to save some cash!

Comments about DOMINATOR Octane Boost:

13b Renesis prefers higher octane but I keep one of these in the trunk for when the price for 87 makes it worthwhile. I also got a few for Dad's old Corvette.

Performance Enhanced!

By

Verified Buyer

Comments about DOMINATOR Octane Boost:

I often use Amsoil Octane Boost products while driving though certain Sates that have heavier Alcohol content in their gasoline. It greatly reduces pinging and adds power responses. I also will use the Octane Boost in the mountains for the basically the same reasons. It's a huge improvement in performance.

Comments about DOMINATOR Octane Boost:

My car requires 98 octane fuel which is not available. This additive makes the car idle smoothly and allowed me to advance the timing to the manufacturer's recommendations.
