AMSOIL P.I. Performance Improver Gasoline Additive

Ideal for both fuel injected and carbureted systems. Dissolves and removes fuel system deposits and other contaminants for improved power and overall performance in gasoline engines. Reduces PCV and EGR system deposits. Reduces exhaust emissions (tests show up to 90 percent reduction). Improves engine idle, response and starting.

An initial clean-up dose of six ounces for ten gallons of gasoline restores up to 95 percent of an injector's original fuel flow. Periodic maintenance doses of one ounce for ten gallons of gasoline keep injectors and other fuel system components clean. (more info)

AMSOIL Diesel Concentrate Performance Fuel Additive

Total system cleaner and lubricity improver for all types of diesel engines. Excellent for ultra low sulfur diesel and biodiesel fuel.

AMSOIL Diesel Concentrate (ADF) provides maximum diesel operating efficiency. It compensates for the variances in quality of different fuels (including biodiesel) and the deficiencies of today’s Ultra Low Sulfur Diesel fuel (ULSD) for better engine operation. New engine technology, tighter tolerances and emission regulations require high-quality diesel fuel for long-term engine operability. AMSOIL Diesel Concentrate meets the low sulfur mandate. It improves diesel fuel quality to exceed today’s stringent performance requirements. AMSOIL Diesel Concentrate extends equipment life, lowers operating costs and improves diesel performance.

AMSOIL Diesel Cold Flow Improver

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. Add AMSOIL Cold Flow Improver to diesel fuel above the fuel cloud point, which is the temperature wax crystals begin to form. Diesel fuel cloud point varies greatly with some lesser-quality diesel fuels forming wax as warm as 40° F (4°C). AMSOIL recommends treating diesel fuel at a minimum of 32°F (0°C), insuring the fuel is properly treated inmost every case. AMSOIL Cold Flow Improver is designed to control wax crystal formation. It does not reverse wax or gel once formed. (more info)
