DOMINATOR® Octane Boost

Improves Performance in all Two- and Four-Stroke Gasoline-Fueled Engines

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.

Synthetic Warehouse local testimonial:

My own 1983 AMC Eagle when pulling our trailer to Omaha – the steep hills south of Beresford, SD on I-29 the Inline Six has trouble keeping speed at 75MPH on these hills. When I run the AMSOIL Octane Boost in a full tank (15 gallons) it has no issues incredibly!!
