Product Details Reviews & Rating

Product Description
AMSOIL DOMINATOR® Octane Boost (AOB) significantly increases engine response and power in all two- and four-cycle gasoline-fueled engines. 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.

Performance Features
• Improves performance
• Maximizes power
• Improves ignition
• Helps fuel burn cleaner
• Removes carbon deposits
• Reduces engine knock
• Improves responsiveness

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

HEALTH & SAFETY
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

Absolutely a must have

I own a high performance snowmobile, so I'm always cautious when i fill up at the pumps as I want 100% premium fuel. Not always the case at gas stations in northern Ontario. Fuel quality seems below the said standard. So I always carry a bottle or two in my tunnel bag to use to bring up the standard that I am always looking for. Cheers

Octane boost, lead substitute, cleaners

The octane boost is self-explainatory if you are running high comp ratio. This product also has lead substitute if you have older car without hardened seats for modern unleaded gas. Also, this is in a carrier of diesel fuel which I can't confirm for sure but, I suspect it suppresses the vapor lock problems of modern gas.

Fantastic

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.

Pump gas isn't always good enough.

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..

Winter storage of my 2014 BMW motorcycle

Living in Washington State, I don't ride my 2014 BMW R1200RT-LC year round so I leave it in the garage hooked up to a Battery Tender, and the gas tank filled with Pure Gas AND 3 oz. of Amsoil's Gasoline Stabilizer. Every summer when I start up my bike there is little hesitation, and the engine settles down to a steady idle. Riding that first tank shows no problems or misses in any RPM range, though I don't get the full mileage of 300 miles, but with the very next tank of gas things are back to normal.

A must for living in a remote location...

I trust Amsoil products, after using them for so many years. Our gasoline gets delivered by barge and then trucked to us. It's always got visible crud in it and I have to put it through a filter first. As soon as I get my gasoline, I filter it and add Amsoil Gasoline Stabilizer. While others in the area have had numerous problems with 'bad gas,' my gasoline has never let me down. It gets used in my Stihl saws, Echo yard equipment, my Polaris Ranger, my portable Honda generator, my Ariens wood splitter, etc. Never a problem.

Re: OWNER

DOMINATOR Octane Boost is designed for off-road & racing application and therefore not recommended for use in vehicles equipped with catalytic converters.

To increase performance of a catalytic converter equipped vehicle, we recommend AMSOIL PI - Performance Improver fuel additive to clean combustion chambers, intake valves and fuel injectors.
