WARNING!

The new Ultra Low Sulfur Diesel Fuel (ULSF) is causing excessive wear to injectors, fuel pump, o-rings, and lift pumps on all diesels.  The rigorous hydrotreating process used to reduce the amount of sulfur in fuel also reduces the fuel's lubricating properties.  Lubricity is a measure of the fuel's ability to lubricate and protect the various parts of the engine's fuel injection system from wear.  This processing also affects cold flow properties, corrosion resistance, and oxidation.  Prolonged use of today's diesel fuel without a supplemental high quality additive could result in injector, o-ring or lift pump failure.  New injectors are about $3500.00 installed.  AMSOIL's Diesel Concentrate (ADF) fuel additive improves lubricity for the best engine protection on the market & will save you money with every application.

Tests show AMSOIL Diesel Concentrate improved mileage by 5%.   At $3.50/gal. of diesel fuel, a 5% savings is 17.5¢. To treat 1 gallon of fuel with Diesel Concentrate (ADF) costs 8¢  meaning your saving 9.5¢/gal. while protecting your engine and experiencing better performance.   ADF will also save you money by extending the service life of expensive fuel filters.

AMSOIL Diesel Concentrate
16 oz. bottle (ADF) 

Diesel Concentrate Performance Fuel Additive (ADF) New Additive
Diesel fuel is dirty. ADF is a total system cleaner and lubricity improver for all types of diesel engines. Tests have proven AMSOIL Diesel Concentrate (ADF) provides maximum diesel operating efficiency.  Super cleans fuel injectors and combustion chamber for improved efficiency, better sealing and minimizes soot loading common in diesels. Improves the oxidation and thermal stability of diesel fuel, improves fuel economy by up to five percent (5%), restores horsepower and protects against water contamination. Excellent for ultra low sulfur diesel and biodiesel fuel.  AMSOIL Diesel Concentrate meets the low sulfur mandate. It improves diesel fuel quality to exceed today’s stringent performance requirements. New engine technology, tighter tolerances and emission regulations require a high-quality diesel fuel for long-term engine operability. Compatible with all types of exhaust emission systems, including diesel particulate filters (DPF's).  AMSOIL Diesel Concentrate extends engine life, lowers operating costs and improves diesel performance.  One bottle treats your first 50 gallons, then use one bottle for every 100 gallons (1oz. per 5 gal).

"I normally used 220 gallons of fuel on my weekly 1100 mile over-the-road truck route, but after adding AMSOIL Diesel Concentrate, I only used 175 gallons. I was amazed"  Ray Jones, Wills Point, TX.

Diesel Injectors 

Cetane Boost (ACB)
16 oz. bottle (ACB)

Cetane Boost Diesel Fuel Additive (ACB)
An ashless, alcohol-free additive that improves cetane up to seven points for increased power and performance in all diesel engines. AMSOIL Cetane Boost Additive improves diesel fuel quality that benefits all diesel engines, especially high performance designs. Supported by extensive testing and years of field trial use, this additive has repeatedly demonstrated its ability to improve diesel engine performance.  Average diesel fuel cetane number is only 40, but high performance diesel engines like Cummins, Powerstroke, and Duramax operate best with cetane values of 50 or higher

Cetane Boost increases fuel economy up to 2%, providing more complete combustion for better performance, power, and drivability.  It controls rapid pressure rise within the cylinder, providing quieter, smoother operation.  This additive reduces white smoke, emissions and odors, reducing environmental impact.  One bottle treats 200 gallons.  Recommend using Cetane Boost in conjunction with Diesel Concentrate, and Cold Flow Improver.

Cold Flow Improver (DFF)
16 oz. bottle (DFF) 

Diesel Cold Flow Improver (DFF) New Additive
Best when added to Diesel Concentrate Fuel Additive (ADF) to improve cold weather performance in applications below 40°F
 
A premium fuel additive that lowers diesel fuel cold flow properties as much as 20°F (11°C). AMSOIL Cold Flow Improver for diesel fuel is designed for use in Ultra Low Sulfur Diesel fuel (ULSD) and conventional fuels. It functions by modifying wax crystal formation at low temperatures to depress the pour point and improve cold flow filtration properties. AMSOIL Cold Flow Improver contains jet fuel-type deicer to help prevent ice formation in fuels contaminated with water. It is recommended for use with all diesel engines and is compatible with diesel exhaust particulate filters (DPFs). AMSOIL Cold Flow Improver is recommended for use in #2 diesel fuel, #1 diesel fuel, kerosene, heating oil and biodiesel.
