AMSOIL has multiple diesel fuel additives for your engine, and OEC stocks them.  They are the most potent on the market.


Removes performance-robbing deposits from diesel fuel injectors to restore horsepower and improve fuel economy.
Formulated for all types of diesel engines, including high-pressure common-rail (HPCR) designs.

-> Minimizes soot generated from incomplete combustion and helps keep soot out of the crankcase. <-
-> Compatible with all types of exhaust emission systems, including diesel particulate filters (DPFs). <-
-> Improves the service life of the fuel pump and injectors, preventing costly repairs. <-
-> Excellent for use with AMSOIL Diesel Cetane Boost and AMSOIL Diesel Cold Flow. <-
-> Adds back the lubricity missing from ultra-low-sulfur diesel fuel (ULSD). <-
-> Restores horsepower and operability to like-new condition. <-
-> Improves fuel economy up to 4.5 percent. <-
-> Improves acceleration. <-

This fuel additive provides many of the same benefits in heating oil furnace applications.  Available in 8-ounce, 16-ounce, and 64-ounce bottles as well as 5-gallon pails and 55-gallon drums.

Formulated with an advanced deicer to enhance fuel flow and help prevent fuel filter plugging in cold temperatures.

-> Useable in a broad range of diesel fuels, including #1 diesel, #2 diesel, biodiesel, and ultra-low-sulfur diesel (ULSD). <-
-> Inhibits wax crystal formation and can improve diesel pour point as much as 58ºF (32ºC). <-
-> Lowers the cold filter-plugging point (CFPP) by up to 20ºF (15ºC) in ULSD. <-
-> Improves engine starting. <-

Must be added at temperatures above the diesel fuel cloud point (the temperature at which wax begins to crystallize).  Will not reverse gel or wax crystals once formed.

Available in 16-ounce bottle, 5-gallon pail, or 55-gallon drum.

Combines the superior detergency of AMSOIL Diesel Injector Clean and the excellent anti-gelling properties of AMSOIL Cold Flow Improver in one convenient package, without sacrificing performance.

Available in 16-ounce bottle, 5-gallon pail, or 55-gallon drum.

Quickly dissolves gelled fuel, thaws frozen fuel filters, and reduces the need for a new filter, saving both money and an inconvenient trip to a parts store.

-> Performs well in all diesel fuels including ULSD, off-road, and biodiesel. <-
-> Cheap insurance against frozen fuel. <-
-> Non-corrosive. <-
-> Alcohol-free. <-

One 30oz. bottle of Diesel Recovery treats 30 gallons of fuel.  Also available in a 1-gallon bottle and a 55-gallon drum.
When encountering a gelled fuel system, AMSOIL recommends taking the following steps for maximum effectiveness:
    Remove the existing fuel filter.
    The filter can be reused, or a new filter can be installed.
    Fill the fuel filter with AMSOIL Diesel Recovery.
    Install the fuel filter.
    Add the remaining Diesel Recovery to the fuel tank.
    Start the engine and allow the fuel system to circulate until full power has been restored.

Raises the cetane number of diesel fuel up to seven points for maximum horsepower, increased fuel economy, and easier starts in all diesel engines.  Fuel with a higher cetane number provides for a more complete burn, resulting in improved performance.

-> Can be used in conjunction with AMSOIL Diesel Injector Clean and AMSOIL Diesel Cold Flow. <-
-> Compatible with biodiesel and all types of exhaust emission systems. <-
-> Excellent for use with ultra-low-sulfur diesel fuel (ULSD). <-

Recommended for use in all types of heavy- and light-duty, on- and off-road and marine diesel engines.  Best performance is achieved when used with every tank of fuel.

Available in 16-ounce bottle, 1/2-gallon container, 5-gallon pail, and 55-gallon drum.
