AMSOIL Diesel Recovery: Maximum Performance in All Types of Diesel Fuel

AMSOIL Diesel Recovery outperforms competition in industry tests

AMSOIL Diesel Recovery (DRC) is an emergency diesel fuel treatment that quickly dissolves the wax crystals that form when diesel fuel has surpassed its cloud point. It liquefies gelled diesel fuel and thaws frozen fuel filters, avoiding costly towing charges and getting diesel vehicles back on the road. Diesel fuel quality varies from one filling station to the next, and low quality fuel can have a cloud point as high as 40 degrees Fahrenheit (4.4 degrees Celsius), making Diesel Recovery a necessity for diesel operators on cold weather climates.

Cold Weather and Diesel Fuel

As 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 clog the fuel filter and starve the engine of fuel or prevent it from starting.

#1 Diesel Fuel

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.

Cold Weather Performance Parameters

AMSOIL Cold Flow Improver (ACF) effectively maintains fuel flow in cold weather, reducing the cold filter plugging point (CFPP) by up to 34 degrees Fahrenheit (19 degrees Celsius) in ultra-low-sulfur diesel fuel (ULSD). However, Cold Flow Improver must be added to diesel fuel before it reaches its cloud point, and it will not dissolve wax or liquefy diesel fuel once wax crystals have formed. AMSOIL Diesel Recovery is specifically formulated to address these problems.

Many competitive products make great claims regarding pour point, leading consumers to believe their products are superior when they actually have an inferior CFPP. Once fuel surpasses its cloud point, the wax crystals begin to clog the filter. The CFPP temperature is a more important characteristic than pour point because the engine will not run if fuel cannot pass through the fuel filter.

AMSOIL Diesel Recovery Proven Superior

Click to Enlarge PhotoIn 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. AMSOIL Diesel Recovery was administered 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's maximum recommended dosage of 32 oz. per 30 gallons of fuel was used in this evaluation.

As the results demonstrate, AMSOIL Diesel Recovery delivers superior performance. In ULSD, Diesel Recovery reduced the fuel's pour point by 27 degrees Celsius and the CFPP by 17 degrees Celsius. Diesel 911, on the other hand, only reduced the pour point of ULSD by 10.5 degrees Celsius and actually INCREASED the fuel's CFPP by .5 degree Celsius.

In B2 biodiesel, AMSOIL Diesel Recovery reduced the fuel's pour point 9 degrees Celsius and reduced the CFPP 19.75 degrees Celsius; while Diesel 911 INCREASED the fuel's pour point 5.25 degrees Celsius and reduced the CFPP only 6 degrees Celsius.

Diesel Recovery reduced the pour point of B5 biodiesel 24 degrees Celsius and reduced the CFPP 16 degrees Celsius. Diesel 911 reduced the pour point of B5 18 degrees Celsius and again INCREASED the CFPP 1.75 degrees Celsius.

Dependable Performance

As state, provincial and federal governments continue to impose new mandates of diesel fuel regarding sulfur and bio-matter content, it is increasingly important to offer products that perform well in all available types of fuel. While fuel systems and fuel quality vary, AMSOIL Diesel Recovery delivers dependable performance in all diesel fuels, including ULSD, off-road and biodiesel. In addition, AMSOIL Diesel Recovery is alcohol-free, making it safe for repeated treatments.

Premium AMSOIL Synthetic Motor Oils offer the longest drain intervals on the market, unsurpassed protection and performance that effectively extends equipment life and improved fuel economy, saving customers money at the pump and reducing the nation's dependence on foreign oil.

"AMSOIL INC. warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL INC. products are used in full compliance with the company's recommendations and instructions."


AMSOIL synthetic motor oils are formulated to surpass engine test specifications, offering protection far greater than competing motor oils for extended drain intervals. Most synthetic oil manufacturers make no claim to extended drain intervals, deferring to the maintenance schedule provided by the vehicle manufacturer. With its unparalleled oil and warranty program, AMSOIL offers consumers unprecedented protection and economics.

Another AMSOIL First

More than 20 years ago, AMSOIL began using the NOACK volatility test as a comparison tool and measurement of quality. Back then, nearly every oil tested side-by-side with AMSOIL synthetic motor oils failed, and those that passed barely squeaked by. Other oil companies paid no attention to NOACK results until Ford Motor Company made it a requirement for service fill oils, validating what AMSOIL had said all along.

THE NOACK Volatility Test
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. AMSOIL Synthetic Motor Oil resists high temperature volatization better than other motor oils. AMSOIL Synthetic Motor Oil maintains peak fuel efficiency and reduces oil consumption and emissions.

AMSOIL Now An ISO Certified Manufacturer
AMSOIL recently received ISO 9001:2000 certification of our Quality Management System (QMS). NSF International Strategic Registrations is the registrar that has verified our QMS meets the requirements of the ISO 9001:2000 standard, the most widely utilized quality standard throughout the world for quality management systems. ISO standards are used by over 300,000 companies worldwide setting rigorous standards for businesses, government and industry.

ISO 9001:2000 is applicable to any manufacturing and service organization providing a framework for system development that focuses on the customer, quality system performance and ongoing improvement. AMSOIL received ISO 9001:2000 registration under the scope: synthetic lubricants blending, packaging, and other fulfillment directly associated with lubricant product.
