Increases Octane Up to 4 Numbers
AMSOIL DOMINATOR Octane Boost 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. It is also excellent as a lead substitute at the same treat rates in collector automobiles, older off-road equipment and pleasure vehicles.

- Reduces engine knock and ping
- Improves ignition and engine response

- Helps fuel burn cleaner
- Maximizes power in 2-stroke and 4-stroke engines
- Excellent lead substitute for collector automobiles

Maximizes Power and Eliminates Knock
"Knock" is an uncontrolled and explosive ignition of hydrocarbon fuel 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 — higher numbers denote greater knock control.
DOMINATOR Octane Boost eliminates knock with the appropriate octane increase, removes carbon deposits, improves ignition and helps fuel burn cleaner for maximum performance.
Dosage & Applications
Most users find one 12-oz. bottle for 15 gallons of gasoline provides the ideal performance increase. Use in all two- and four-stroke gasoline-fueled engines. Excellent as a lead substitute in collector automobiles and older equipment.

I purchased three products from AMSOIL, The Upper Cylinder Lubricant Corrosion Inhibitor, The DOMINATOR® Octane Boost, and The P.i.® Performance Improver Gasoline Additive I added all three to a full tank but, prior to doing this, I had filled the tank with Top Tier Fuel for this test Shortly after I took a ride, at first, I noticed nothing, but the very next day I put twenty miles on her, and that is when I noticed she ran quieter, and that the pick-up was back I highly recommend this product for older vehicles, and I want you to know, that these products are not a gimmick Check it out for yourself
