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.

    Best Glass Cleaner Ever
    By  Whitesheep,  a  Verified Buyer  from  Phoenix AZ  on  October 19, 2021

    Describe the issue

    We don't have many bugs other than their poop here in AZ, but we get nasty rain dirt and hard water stains from sprinklers. This stuff is a little more time consuming to use, but it works great. Try a can and you will not go back to the other window stuff.
    Bottom Line
    Yes, I would recommend this to a friend.

    Amsoil Dominator Octane Boost Performance
    By  STACY,  a  Verified Buyer  from  Central Maine  on  July 07, 2021

    Describe the issue

    I have been using the Amsoil Dominator Octane Boost product for the past year in my custom 70' Mustang with a 402R Roush performance engine based upon my mechanic's recommendation and I have been extremely satisfied with its performance. Definitely has eliminated the valve knocking sound as well as dieseling experienced with regular pump gas. I believe it has also slightly improved gas mileage, but I am not so interested in that as I am in power output. I do notice some improvement in engine output and the car seems to just run better overall. Highly recommend the product and will keep on using it!
    Bottom Line
    Yes, I would recommend this to a friend.
