DOMINATOR® Octane Boost



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.

    A Noticble Difference
    By  GLEN,  a  Verified Buyer  from  Northern New Mexico  on  December 25, 2020

    Describe the issue

    I saw this on the Engine Masters show, sponsored by Amsoil and tried this in a high performance 502 cu. in. engine that runs on pump gas. Don't know if it really increases the octane number but it makes a notable difference in engine performance. Starts quicker, idles (big cam), runs much smoother, and stopped the dieseling completely. Just getting the engine to idle at 7500 feet altitude is worth the the cost.
    Bottom Line
    Yes, I would recommend this to a friend.

    I have been using AMSOIL products for about 40 years. They have always had superb lubrication products for whatever your application is. Recently I was introduced to the Octane Boost. I have my 2019 Mustang tuned to a bottle added to almost every other tank. Man what a difference. Thanks AMSOIL.
