Maximizes Power & Performance

When treated at 1.3 oz. per gallon of fuel, Motorcycle 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 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 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 Motorcycle Octane Boost treats four to six gallons of gasoline.

Applications

Motorcycle 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.

What is “engine knock” and why does it matter?

“Knock” is an uncontrolled and explosive ignition of a hydrocarbon fuel, such as gasoline, in the combustion chamber. It causes a knocking or pinging sound, robs the engine of power and, left unchecked, causes serious engine damage. Fuel’s tendency to knock is measured by its octane number. Lower numbers denote greater knock tendency; higher numbers denote greater knock control. Knock may be eliminated with the appropriate octane number.

For maximum convenience and cost-effectiveness, equipment and vehicles used seasonally, such as motorcycles, snowmobiles, personal watercraft, snowblowers, outboard motors and classic cars, need to start easily and run properly when removed from storage. Gasoline, however, is not formulated for long-term storage and can start to degrade in as little as 30 days. Degraded fuel leads to varnish and sludge that clog injectors, fuel lines and carburetors; stick floats; and cause poor engine performance, starting problems, increased maintenance expenses and decreased equipment life.

AMSOIL Gasoline Stabilizer (AST) inhibits the oxidation process that occurs when fuel is stored for extended periods, improving performance, extending equipment life and decreasing maintenance expenses.

Delivers Confidence

Treating fuel with AMSOIL Gasoline Stabilizer prior to storing equipment provides confidence. It offers peace of mind that equipment will not only start when it is needed, but will also perform properly.

Eliminates Need to Drain Fuel

Draining fuel from equipment can not only be difficult, it invites corrosion on the bare metal in the tank and drying and cracking of gaskets and seals. Some fuels are pre-treated with oxidation inhibitors that allow them to be stored for short periods without forming excessive deposits, while other fuels have no inhibitors at all. AMSOIL Gasoline Stabilizer eliminates the need to drain fuel from equipment before long-term storage. It fights fuel deterioration, severely limiting the formation of damaging varnish and deposits to help extend equipment life.

Decreases Maintenance

Deposits, varnish and sludge that form from degraded fuel can cause important components in the fuel system to become clogged or stuck and require thorough cleaning or replacement. AMSOIL Gasoline Stabilizer helps reduce maintenance time and costs by preventing harmful deposits from forming in the tank and fuel system, eliminating the need to clean or replace carburetors after long-term storage.

  • Helps keep fuel from deteriorating
  • Protects against varnish and gum buildup
  • Fights ethanol corrosion

Applications

AMSOIL Gasoline Stabilizer is engineered for use in, but not limited to, motorcycles, snowmobiles, ATVs, UTVs, outboard motors, stern-drive and inboard marine engines, personal watercraft, lawn equipment, chainsaws, snowblowers, portable generators, handheld power equipment, motor scooters, powered farm equipment, powered construction equipment, cars and trucks.

Dosage recommendation

One ounce of AMSOIL Gasoline Stabilizer treats 2.5 gallons of fuel, including fuel that contains up to 10 percent ethanol.

Before storing equipment, treat it with the appropriate dose of AMSOIL Gasoline Stabilizer. Let the engine run for five to 10 minutes to thoroughly circulate the additive through the fuel system. Stop the engine and store the equipment in a dry, covered location.

Degraded fuel presents a major maintenance issue in small engines and powersports equipment. It can form varnish, gum and insoluble debris that clog carburetors, fuel injectors and fuel filters. Carbon buildup can form on the tops of pistons, causing pre-ignition, rough idling and poor throttle response. Fuel-related problems are only expected to intensify in the coming years as the ethanol content in pump gasoline continues to increase.

AMSOIL Quickshot (AQS) is a premium fuel additive formulated to thoroughly clean and restore peak performance in small engine and powersports equipment fuel systems. It also stabilizes fuel between uses and during short-term storage. Its revolutionary technology focuses on three major fuel-related issues plaguing these applications: ethanol, water and dirty pump gas.

Phase Separation

Ethanol

Ethanol in fuel has a tendency to absorb water and separate from the gasoline (a process known as phase separation), sinking to the bottom of the gas tank where it quickly degrades and creates gum, varnish and other insoluble debris that can plug fuel-flow passages and negatively affect engine performance. When this ethanol/water mixture is pulled into the engine, it creates a lean-burn situation that increases combustion chamber temperatures and can lead to engine damage. AMSOIL Quickshot is designed to keep water dispersed throughout the fuel tank, moving it out as a normal part of operation and decreasing the chance of ethanol separating from the gasoline.

Quickshot was tested in fuel containing 10 percent ethanol. Controlled plugging of injectors showed a 70 percent flow improvement, while oxidation stability improved 44 percent over untreated fuel.

Water

Water finds its way into gas tanks through condensation in tanks open to the atmosphere, gas pumps and other environmental conditions, and if left untreated, will cause starting, performance and corrosion problems. By keeping water dispersed in tiny molecules and safely moving it out of the tank through the combustion chamber, Quickshot helps maintain engine performance and protects against damaging corrosion.

Dirty Gasoline

Dirty gasoline causes fuel-system gumming and varnish, as well as piston and combustion chamber deposits. Although all gasoline sold in the U.S. is formulated with a lowest additive concentration (LAC) level of detergent additives, these detergent levels are not enough to prevent deposits from building up on critical fuel system components. Quickshot contains unique chemistry that quickly detaches and carries away deposits and buildups in fuel systems, injectors and carburetors, while also cleaning hard-to-remove deposits on piston tops, spark plugs and other combustion chamber parts.

Applications

Quickshot (AQS) is recommended for use in all two- and four-stroke gasoline-powered engines, including motorcycles, snowmobiles, boats, personal watercraft, ATVs, edgers, tillers, mowers, snowblowers, chainsaws, generators and farm and construction equipment. However, AMSOIL P.i.® Performance Improver is the superior choice for passenger vehicle applications.

Recommendations

Quickshot is designed for an initial clean-up dose of 8 oz. per 6 gallons of gasoline, followed by 8 oz. per 12 gallons thereafter. Slight overtreatment has no negative consequences.

Untreated Fuel Leads to Poor Engine Performance

A vehicle demonstrates its best efficiency and engine performance when it is new. As the engine ages, its performance suffers from gasoline fuel-generated deposits that form on the fuel injectors, intake valves and combustion chamber. Additives are required to control deposit formation.

Today’s fuels, however, lack sufficient treatments of either enough additives or high quality additives. Fuel system deposits result in the following:

  • Lost fuel economy
  • Lost power and poor throttle response
  • Failed emission tests
  • Poor drivability – surging, hesitation, stalling, rough idle
  • Engine knocking (pinging) and rap
  • Difficult starts

Treated Fuel Delivers Maximum Performance

AMSOIL P.i. is the most potent gasoline additive available today. As a concentrated detergent, it is unsurpassed in cleaning combustion chamber deposits, intake valve deposits and port fuel injector deposits. AMSOIL P.i. helps maintain peak engine efficiency, fuel economy, power and drivability in newer low mileage engines. In engines with accumulated deposits, testing showed AMSOIL P.i. provided the following clean-up benefits after only one tank of gasoline:

  • Improves fuel mileage an average of 2.3% and up to 5.7%
  • Reduced emissions

    • hydrocarbons (HC) up to 15%
    • carbon monoxide (CO) up to 26%
    • nitrous oxides (NOx) up to 17%
  • Restored power and performance
  • Reduced need for costly higher octane fuel
  • Reduced noise from carbon rap and pre-ignition
  • Better drivability
  • Smoother operation

AMSOIL P.i. works as an emissions passer. It is ideal for use prior to emissions inspections.

Unsurpassed Deposit Clean-up

Port Fuel Injector Deposits form after the engine has been shut down and there is no gasoline flowing through the injectors. During this “hot soak” period the injectors heat up and the gasoline remaining in the injectors degrades and forms deposits. This can happen very quickly with the use of poor quality gasoline and short trip driving. Because the clearances within the injectors are extremely tight and injectors must deliver precise amounts of “atomized” fuel, even small amounts of deposits can cause injectors to malfunction. Fuel flow is reduced and spray patterns are disrupted, decreasing engine efficiency, power and fuel economy, while increasing exhaust emissions.

Injector Cleanup Total Test Miles %Flow

Intake Valve Deposits form on the intake side or back side of the valves. As deposits increase, they restrict airflow and alter airflow patterns in the cylinder. The deposits disrupt the balanced air/fuel ratio by momentarily absorbing and releasing fuel, and they can cause valve sticking by getting in the way of the valve stem and guide. Deposits also restrict proper seating, and the valves may be burned. Intake valve deposits cause lost engine power, increased emissions, poor engine efficiency and potential valve failure.

Combustion Chamber Deposits form on the top of the pistons and on the cylinder heads. They increase compression and absorb heat during combustion to later release it during the intake cycle. In some engines with tight squish domes, combustion chamber deposits cause the piston to actually hit the cylinder head. This is referred to as combustion chamber deposit interference or carbon rap. Combustion chamber deposits also flake off as they get large, and these flakes can get trapped between the valves and valve seat, resulting in compression loss, difficult starting and rough idle.

Higher compression and stored heat cause increased intake fresh charge temperatures and the increased likelihood of pre-ignition knock or pinging when the fuel spontaneously combusts prior to spark ignition. This increases emissions and may cause engine damage. Many of today’s cars have knock sensors that adjust spark timing to prevent knock.

Although audible knock is controlled, power is lost from retarded timing. Higher octane fuels of 4-5 octane numbers can be used to help prevent knock, an effect called octane requirement increase. As a vehicle ages, more-expensive, higher-octane fuel is needed to keep it operating at peak performance. By cleaning combustion chamber deposits, knock is controlled, power is restored, fuel economy increases and higher-octane fuels are less necessary for peak performance.
