 Motorcycle Octane Boost
Maximizes Power and
Efficiency
Product Highlights
Increases octane for power and efficiency. It is designed to improve startup performance and eliminate engine ping
and knock for increased power at low-rpm operation. Contains detergents that help combustion chambers and fuel
delivery systems maintain cleanliness for optimum performance.

Maximizes Power & Performance
When treated at 1.3 oz. per gallon of fuel, Motorcycle Octane Boost increases the octane of gasoline up to three
numbers. Increased octane improves power and can eliminate performance-robbing and potentially damaging engine
knock or ping (see below).
Improves Low-rpm Performance
Engine knock is especially noticeable in some motorcycles during idle or low-rpm operation and high-temperature
driving. Most modern bikes are equipped with sophisticated knock-detection systems that can alter spark timing and
the air-to-fuel mixture until knock ceases. Although these systems protect the engine from damage, they can also
cause reduced horsepower and poor low-rpm operability. AMSOIL Motorcycle Octane Boost helps reduce the need for
knock-detection systems to compensate, ensuring maximum low-rpm power and performance in modern bikes.
Cleans Harmful Deposits
Because Motorcycle Octane Boost contains active detergents, it can
help maintain efficiency. For clean up, however, AMSOIL recommends treating gasoline with AMSOIL Quickshot®, which
contains a greater concentration of cleaning agents.
What is engine knock and why does it matter?
The tendency of a hydrocarbon fuel, such as gasoline, to knock is measured by its octane number. Lower numbers
denote a greater knock tendency; higher numbers denote greater knock control. “Engine knock” is a reference to the
sound made from an uncontrolled and early ignition of fuel in the combustion chamber. It causes a knocking or
pinging sound, robs the engine of power and can cause catastrophic engine damage. Knock may be eliminated by
increasing the fuel's octane.
What is Research Octane Number?
Research Octane Number (RON), Motor Octane Number (MON) and Anti-Knock Index (AKI) are the three most common octane
ratings. AKI, the rating with which most North American motorists are familiar, is typically displayed on gas pumps
as the average of the fuel's RON and MON [(R+M)/2]. RON, however, is the most common industry rating. Therefore,
AMSOIL uses the RON rating when conducting performance tests and product validation. Gasoline's RON generally is a
few numbers higher than the AKI posted on the gas pump (e.g. 87 octane fuel, or regular pump gas, has a RON of
about 91-92).
When marketing their products, some additive manufacturers have adopted a points system where 10 points equals
one octane number. A claim that an additive increases octane 30 points translates into an increase of three octane
numbers. This approach is often used only to artificially strengthen marketing claims and is not endorsed by
AMSOIL.
Treat Rate
One 4-oz. bottle of AMSOIL Motorcycle Octane Boost treats four to six gallons of
gasoline.
APPLICATIONS
Motorcycle Octane Boost is primarily recommended for use in four-stroke air- or liquid-cooled motorcycles
manufactured by Harley-Davidson®, Yamaha®, Honda®, Ducati®, BMW®, Triumph® and all other four-stroke motorcycles.
It may be used in off-road applications, including ATVs, UTVs and snowmobiles, as an alternative to AMSOIL
DOMINATOR® Octane Boost. Note: Clean spills immediately using a clean towel. If left standing, Motorcycle Octane
Boost can stain painted or metal surfaces. If cleaned immediately, there is no need for concern.
