ADDITIVES

IMPROVES FUEL QUALITY FOR PEAK PERFORMANCE
Fuel with a higher cetane number provides for a more complete burn, resulting in improved performance. Diesel Cetane Boost increases cetane up to eight points
Improves the ignition quality of diesel fuel, maximizing available power and improving starting
Increases fuel economy, smooths idle and reduces smoke & emissions
Recommended for use in all types of heavy- and light-duty, on-and off-road and marine diesel engines
Safe for use in all diesel fuels, including biodiesel

Improves Fuel Quality for Peak Performance
Fuel with a higher cetane number provides for a more complete burn, resulting in improved performance. By increasing cetane, Diesel Injector Clean + Cetane Boost improves the ignition quality of diesel fuel, maximizing available power and improving starting. It also smooths idle and reduces smoke and emissions.

Extends Filter Life
Extends Filter LifeModern diesel engines run hot, raising the temperature of the fuel returned to the tank and causing carbonaceous deposits that collect in the fuel filter (see picture), plugging it and causing premature failure issues. AMSOIL Diesel Injector Clean + Cetane Boost effectively protects against deposits, extending fuel filter life.

RECOMMENDATIONS
Diesel Injector Clean + Cetane Boost is recommended for use with all types of heavy- and light-duty, on- or off-road and marine diesel engines. Add before filling tank. Initial use: follow clean-up recommendation. Subsequent uses/regular treatment: follow maintenance recommendation. To prevent cold-weather fuel issues, add AMSOIL Diesel Cold Flow or switch to AMSOIL Diesel All-In-One.

HELPS EQUIPMENT START RELIABLY
• Eliminates the need to drain fuel from equipment before long-term storage.
• Offers peace of mind that equipment will not only start when it is needed, but will perform properly.
Gasoline Stabilizer Improves Stability
Gasoline Stabilizer provides fuel stability that Sea Foam Motor Treatment can’t match, helping maintain startability and protect against the formation of varnish and gum.

FIGHTS ETHANOL PROBLEMS
Designed to keep water due to ethanol dispersed in tiny molecules throughout the fuel tank, moving it out as a normal part of operation.
Helps maintain engine performance and protects against damaging corrosion.
Decreases the chance of ethanol separating from the gasoline, helping prevent lean-burn and combustion-chamber damage.

Capless-Compatible Packaging
Many new vehicles have replaced traditional fuel caps with capless systems. The threads on most bottles restrict them from opening the flap inside the fuel neck and make removing the bottle difficult. The AMSOIL Upper Cylinder Lubricant bottle is fully compatible with capless fuel systems. It’s easy to insert, pour and remove the bottle.

RECOMMENDATIONS
For use with cars and trucks.
For best results, use with every tank of fuel. Do not refill tank until almost empty.
Treats up to 25 gallons. Add entire bottle to tank at fill-up.
Treat large gas tanks with two bottles of Upper Cylinder Lubricant. Using more than two bottles is not recommended.
Safe for use with catalytic converters, oxygenated gas and up to 15 percent ethanol-blended fuels. Do not use with E85 fuel.
Do not use with two-stroke or diesel engines.
