Use AMSOIL Fuel Additives to Improve 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.

GASOLINE FUEL ADDITIVES


P.i. Performance Improver Gasoline Additive

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)


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.


Quickshot®

Premium fuel additive formulated to thoroughly clean and restore peak performance in small engine and powersports equipment fuel systems.


DOMINATOR® 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.


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


Diesel Injector Clean

Removes performance-robbing deposits from diesel fuel injectors to restore horsepower and improve fuel economy. It is formulated for all types of diesel engines, including high-pressure common-rail designs. AMSOIL Diesel Injector Clean makes no sacrifices; it is purpose-built for diesel owners who demand maximum results.


Diesel Injector Clean + Cetane Boost

Combines the benefits of AMSOIL Diesel Injector Clean and Diesel Cetane Boost in one convenient package. Delivers outstanding detergency, improved lubricity and increased horsepower and cetane


Diesel Recovery

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. For preventative maintenance, use Diesel Cold Flow (ADD) or Diesel All-In-One (ADB).


Diesel Cold Flow

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


Diesel Cetane Boost

Delivers confidence in your diesel’s performance. Concentrated formula uses unique chemistry to target and eliminate specific performance issues, maximizing diesel power.
