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
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
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
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.
One 4-oz. bottle of AMSOIL Motorcycle Octane Boost treats four
to six gallons of gasoline. Slight overtreatment causes no issues,
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.
