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
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.
