Product Details Reviews & Rating

Product 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.

Product Description
AMSOIL Motorcycle Octane Boost (MOB) 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. Motorcycle Octane Boost contains detergents that help combustion chambers and fuel delivery systems maintain cleanliness for optimum performance. At the recommended treat rate, it does not harm catalytic converters or oxygen sensors and is compatible with all other AMSOIL fuel additives.

Maximizes Power and 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. Slight overtreatment causes no issues.

HEALTH & SAFETY
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

Touring Bike Essential

I tour extensively throughout North America on a Harley-Davidson CVO Ultra Classic. The 110 cu. in. engine has been modified to improve its performance, primarily to increase mid range torque, essential for the fully loaded / two up riding that's my norm. My route preference is always far off the beaten path, as far from the interstates as possible. Quite often, I wont find the premium gas that my bike needs or the octane of the purchased fuel is questionable. AMSOIL Motorcycle Octane Boost solves the problem. Simple, pour one into tank, motor is happy again, we ride on!. I don't leave home without it, beats all the others out there!

Hard to say ....

I bought a bottle of this and used it in my BMW motorcycle recently this year. Honestly you really can't say much using only one bottle so I don't know what to say. Unless you had some kind of testing equipment and did an actual test on whatever you were using it in I don't know if you would notice much. It's kinda like taking supplements unless you do it for awhile and then quit you may notice the difference but it is very subtle.

Ethanol Free Fuel and Octane Boost

Whenever I can, I try to find gas stations that sell Ethanol Free gas. I prefer that for these high compression ration engines (and it's also recommended in the bike manual). If I can't find it, this Octane Boost does a great job as a stand-in. I try to keep a bottle or two in my saddlebag just to cover those occasions.

Octane boost

I live in Las Vegas and work in California and their fuel there sucks. Tons of watered down fuel from all companies. I use the octane boost while I'm there and it extends my mileage. I ride a Goldwing and I'd get terrible fuel mileage, but 1 bottle of boost and I'd get about 25 more miles to the tank.

Winter storage of my 2014 BMW motorcycle

Living in Washington State, I don't ride my 2014 BMW R1200RT-LC year round so I leave it in the garage hooked up to a Battery Tender, and the gas tank filled with Pure Gas AND 3 oz. of Amsoil's Gasoline Stabilizer. Every summer when I start up my bike there is little hesitation, and the engine settles down to a steady idle. Riding that first tank shows no problems or misses in any RPM range, though I don't get the full mileage of 300 miles, but with the very next tank of gas things are back to normal.

A must for living in a remote location...

I trust Amsoil products, after using them for so many years. Our gasoline gets delivered by barge and then trucked to us. It's always got visible crud in it and I have to put it through a filter first. As soon as I get my gasoline, I filter it and add Amsoil Gasoline Stabilizer. While others in the area have had numerous problems with 'bad gas,' my gasoline has never let me down. It gets used in my Stihl saws, Echo yard equipment, my Polaris Ranger, my portable Honda generator, my Ariens wood splitter, etc. Never a problem.
