Diesel Concentrate Performance Fuel Additive (ADF)
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"

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.

Diesel Recovery Emergency Fuel Treatment (DRC)
AMSOIL Diesel Recovery quickly liquefies gelled fuel, thaws frozen fuel filters and reduces the need for a new filter, saving both money and avoiding costly towing charges and getting diesels back on the road. Performs well in all diesel fuels, including ULSD, off-road and biodiesel. Cheap insurance against frozen fuel.
One 30 oz. bottle quickly dissolves 30 gallons of gelled fuel to allow the operator to continue driving with minimal downtime. It thaws frozen fuel filters and reduces the need for a new filter, saving money and preventing an inconvenient trip to an auto parts store.
