V-Twin Motorcyclists – Sioux Falls has your Octane Boost

AMSOIL’s Motorcycle Octane Boost Produces Surprising Power

A Sioux Falls favorite. Customers don’t know what to expect and are pleasantly surprised! This is more than just an Octane Boost!

It’s the easiest and the most difficult product to sell!! Yes, people who use this are blown away by how well it works beyond what they expected. Assumed it would simply control the knock or pre-detonation and the bonus was instant low end throttle response and responsive acceleration. It also helps burn off carbon air cooled V-Twins are known for. But it’s one of the products they come back to our Sioux Falls store just for another bottle with a big smile on their face.

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).

Motorcycle Octane Boost 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 in V-Twin Engines

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.

Gasoline Treat Rate

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

Motorcycle Octane Boost APPLICATIONS

Motorcycle Octane Boost Reviews

Best Octane Booster

By  DENNIS,  a  Verified Buyer  from  Alabama   on  May 05, 2025
Whenever you’re ordering oil for next oil change, give this little guy a try. Good combo to boost 87 ethanol free to 91, instead of mixing gas levels to achieve perfect octane

Highly Recommend

By JOHN,  a  Verified Buyer from  Arvada, CO on  June 22, 2024

I use the octane boost in my 2019 HD Road glide. I upgraded my motor with a stage IV kit & improves the performance exceptionally by using regularly. Also is great for road trips when you fuel multiple times, you never know the quality of premium fuel on the road. My wife has a 2019 Spyder, which we use the octane boost in too.

Extended Miles

By  FRED,  a  Verified Buyer  from  Holyoke, CO  on  June 20, 2024

Even though it’s a Harley, getting more miles per gallon is always a plus

 

 

By  ROB,  a  Verified Buyer  on  May 13, 2024

I run this in my first tank of fuel after the winter storage each year and it runs like it has fresh gas in it from the pump after sitting all winter no hesitation or sputter any more
