DOMINATOR® Octane Boost

Improves Performance in all two and four-stroke petrol engines.


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 to burn more cleanly.


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 DOMINA-TOR 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.
