AMSOIL Fuel Additives Improves Your Vehicle's Performance

Unlike "all-in-one" additives, AMSOIL fuel additives are formulated to provide quick results.
When vehicle performance or fuel economy decline, many motorists turn to fuel additives to solve the problem. There are several brands available, and most promise some combination of the following benefits: 
  • Increased fuel economy
  • Smoother engine operation
  • Reduced emissions
  • Maximum horsepower
However, while motorists expect fuel additives to deliver nearly immediate results, typical “all-in-one” additives require use for several tanks of fuel before providing any noticeable performance improvement. Most people don’t want to wait that long or commit to buying several bottles of a fuel additive.

Engine condition plays a vital role in additive performance

To understand why additive performance varies, you should understand why your engine may need a fuel additive in the first place. For optimum fuel efficiency and lower emissions, fuel must first be atomized into a fine mist prior to combustion. Over time, injector deposits produce irregular spray patterns with heavy streams of gasoline that reduce performance (see injector “before” image), while intake valve deposits also decrease efficiency. Today’s injectors are highly engineered to tight tolerances, and even minute deposits interfere with the spray pattern and reduce power and fuel economy. The problem is especially pronounced in newer high-pressure common-rail (HPCR) diesel engines and in direct-injection engines that locate the injectors in the combustion chamber, exposed to intense heat.  

Additive concentration matters

Fuel additives help clean engine deposits and restore lost power and improve fuel economy. However, most additives don’t contain a sufficient concentration of cleaning agents and other performance-improving chemicals to provide the nearly immediate results you expect. Instead, after using the additive with every tank of fuel, over some period of time – possibly weeks to months – you may experience a slight up-tick in power, fuel economy or drivability. Continued use with every tank of fuel maintains engine performance.

AMSOIL fuel additives, however, are different. As performance concentrates, they boast potent formulas designed to provide nearly immediate results.

AMSOIL applies the same philosophy to all AMSOIL fuel additives. For example, AMSOIL Diesel Injector Clean provides the lubricity needed to protect the fuel pump and injectors while cleaning deposits for peak performance. AMSOIL Quickshot, meanwhile, cleans powersports fuel systems and fights ethanol problems to help you get the most out of your motorcycle, snowmobile, lawn mower and other equipment.

Gasoline Fuel Additives
Performance Improver

P.i. improves fuel mileage an average of 2.3% and up to 5.7%. Reduces emissions such as hydrocarbons (HC) up to 15%, carbon monoxide (CO) up to 26% and nitrous oxides (NOx) up to 17%. Restores power and performance. Reduces the need for costly higher octane fuel. (API)


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.

Gasoline Stabilizer

Reduces the oxidation process that occurs when fuel is stored for extended periods to prevent the formation of varnish and sludge which can clog injectors, stick floats and cause poor engine performance. Ideal for stored seasonal equipment such as snowmobiles, lawnmowers, motorcycles and boats. inhibits the oxidation process that occurs when fuel is stored for extended periods, improving performance, extending equipment life and decreasing maintenance expenses.

Octane Boost

Maximizes power and improves performance in all two-cycle and four-cycle gasoline engines. Increases octane up to 4 numbers. Reduces engine knock, improves ignition and engine response, helps fuel burn cleaner and inhibits corrosion. Recommended for off-road and racing use. DOMINATOR Octane Boost is also excellent as a lead substitute at the same treat rates in collector automobiles, older off-road equipment and pleasure vehicles. 

Motorcycle Octane Boost

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. Contains detergents that help combustion chambers and fuel delivery systems maintain cleanliness for optimum performance.

Diesel Fuel Additives
Injector Clean

AMSOIL Diesel Injector Clean (ADF/ADFP) removes performance-robbing deposits from diesel fuel injectors to help restore horsepower and improve fuel economy. It is formulated for all types of diesel engines, including high-pressure common-rail designs. Diesel Injector Clean is formulated to clean both the tough-to-remove internal diesel injector deposits surfacing in modern high-pressure common-rail diesel engines and traditional carbonaceous deposits. 

Cold Flow

AMSOIL Diesel Cold Flow (ACF) combats diesel fuel gelling by improving diesel cold-flow ability. It is formulated with an advanced deicer to enhance fuel flow and help prevent fuel filter plugging in cold temperatures. Diesel Cold Flow is formulated for a broad range of diesel fuels, including biodiesel and #1 and #2 ultra-low-sulfur diesel (ULSD).

Injector Clean
+ Cold Flow

AMSOIL Diesel Injector Clean + Cold Flow (DFC) combines the superior deposit-removing properties of AMSOIL Diesel Injector Clean and the excellent anti-gelling properties of AMSOIL Diesel Cold Flow in one convenient package. It is designed for all types of diesel engines, including high-pressure common-rail designs.

Cetane Boost

AMSOIL Diesel Cetane Boost (ACB) raises the cetane number of diesel fuel up to seven points for maximum horsepower, increased fuel economy and easier starts in all diesel engines. Diesel engines operate best on fuel with cetane values of 50 or higher. Most diesel fuel sold in North America has a cetane value of 40-45. AMSOIL Diesel Cetane Boost makes no sacrifices; it is purpose-built for diesel owners who demand maximum results. 

Recovery Emergency
Fuel Treatment

AMSOIL Diesel Recovery (DRC) is an emergency diesel fuel treatment that dissolves the wax crystals that form when diesel fuel has surpassed its cloud point. Diesel Recovery liquefies gelled diesel fuel and thaws frozen fuel filters, avoiding costly towing charges and getting diesels back on the road.
