Diesel engines become less efficient over time. Fuel injector deposits interrupt spray patterns, causing poor atomization, incomplete combustion, excessive emissions and smoke. Test prove that AMSOIL Diesel Concentrate cleans dirty injectors, improving fuel economy by up to 5 percent and restoring horsepower to like new condition.

Acceleration is improved  and with regular use, Diesel Concentrate continues to enhance performance by keeping injectors clean. The net savings on fuel expense can result in no additional cost to vehicle operation. For a company operating a fleet of large trucks, a 5 per improvement in fuel economy can have a substantial financial impact.

AMSOIL offers Diesel Concentrate Plus Cold Flow Improver (DFC): a convenient combination of two fuel additives in one bottle. Diesel concentrate Plus Cold Flow Improver delivers improved efficiency and cold temperature performance.

While Cold Flow Improver helps prevent diesel fuel from gelling in cold temperatures, 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 in applications not treated with Cold Flow Improver. Diesel Recovery liquefies gelled diesel fuel and thaws frozen fuel filters, avoiding costly towing charges and getting diesels back on the road.

In order to test the performance capabilities of AMSOIL Diesel Recovery, AMSOIL commissioned an independent laboratory to perform an evaluation. Three types of diesel fuel were used in the testing , including ultra-low-sulfur diesel (ULSD), B2 biodiesel and B5 biodiesel. Three samples of each fuel-type were tested: one treated with AMSOIL Diesel Recovery, one treated with Power Service Diesel 911 and one untreated sample. Diesel Recovery was adminstered at the recommended treat rate of 30.oz per 30 gallons of fuel. The treat rate for Diesel 911 varies according to package size; Power Service maximum recommended dosage of 32.oz per 30 gallons of fuel was used in this evaluation.

Results of the diesel fuel additives, AMSOIL Diesel Recovery delivers superior performance. In ULSD, Diesel Recovery reduced the fuel’s pour point by 27C and the cold filter-plugging point (CFPP) by 17C. Diesel 911, on the other hand, only reduced the pour point of ULSD by 10.5C and actually increased the fuel’s CFPP by .5C.

In B2 biodiesel, AMSOIL Diesel Recovery reduced the fuel’s pour point 9C and reduced the CFPP 19.75C; while Diesel 911 increased the fuel’s pour point 5.25C and reduced the CFPP only 6C. Diesel Recovery reduced the pour point of B5 biodiesel 24C and reduced the CFPP 16C. Diesel 911 reduced the pour point of B5 18C and again increased the CFPP 1.75C.

As the temperature drops, the wax naturally found in diesel fuel begins to form crystals. The point at which wax crystals form is known as the cloud point. These wax crystals eventually clod the fuel filter and starve the engine of fuel or prevent it from starting.

One traditional solution to cold-weather problems in diesel engines is the use of #1 diesel fuel, which is diesel fuel diluted with kerosene. While #1 diesel fuel has an advantage in low-temperature operability, there are also several disadvantages. The energy content of #1 diesel fuel is about 95 percent of #2 diesel fuel, resulting in reduced fuel economy and less horsepower. In addition, the kerosene used in #1 diesel fuel provides less lubrication for the fuel pump and fuel distributor, increasing the likelihood for wear on these critical components.AMSOIL DIESEL RECOVERY is a Diesel Fuel Treatment to correct this problem.
