AMSOIL Diesel Cetane Boost (ACB) raises the cetane number of diesel fuel up to seven 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. AMSOIL Diesel Cetane Boost makes no sacrifices; it is purpose-built for diesel owners who demand maximum results.
Fuel with a higher cetane number provides for a more complete burn, resulting in improved performance. By increasing cetane, AMSOIL 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).

I use this in my 17 Chevy Colorado Diesel and it works well to smooth the engine with better performance. I use the minimum of 2 ounces to boost the octane 3 pts and I cannot believe how much better the engine sounds and runs

I travel full time pulling a 41 ft Montana 5th wheel with my 2014 Ram 3500, so fuel economy is very important. Depending where in the country I am, I have seen as much as an additional 3 mpg using the octane boost

Noticed no difference in economy or power.

The length of the spout is useless. I have to pour the Amsoil into a Chevron bottle just to put it in my cars. Same with all your gas additives.

I use it in a 2012 deramax. It pulls daily about 15,000lbs or more. This product helps on everything.
