Product Highlights View Full Description

AMSOIL Diesel Cetane Boost (ACB) raises the cetane number of diesel fuel up to eight points for maximum horsepower, increased fuel economy and easier starts in all diesel engines.

Diesel engines operate best on fuel with cetane values of 50 or higher. Most diesel fuel sold in North America has a cetane value of 40-45. Diesel Cetane Boost delivers confidence in your diesel’s performance. Its concentrated formula uses unique chemistry to target and eliminate specific performance issues, maximizing diesel power.

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 Cetane Boost improves the ignition quality of diesel fuel, maximizing available power and improving starting. It also smooths idle and reduces smoke and emissions.

Diesel Cetane Boost is recommended for use in all types of heavy- and light-duty, on-and off-road and marine diesel engines. Best performance is achieved when used with every tank of fuel. Excellent for use with ultra-low-sulfur diesel fuel (ULSD). Compatible with biodiesel and all types of exhaust emission systems, including diesel particulate filters (DPFs). Follow the chart below.
