Do Cetane Boosters Work?

First and foremost, a cetane additive impacts the cold-temperature performance of your engine. That means reducing the likelihood of no-starts, misfires, torque fluctuations, noise and vibrations. A cetane booster can also mean a smoother idle, more power, more miles per gallon and a longer engine life.

Is cetane good for diesel?

Why do cetane numbers matter? The higher a fuel's cetane number, the quicker it ignites — and that carries a variety of benefits for diesel equipment. From increased fuel economy to fewer emissions to better power output, fast combustion is key to a diesel engine's performance.

How often should you use cetane booster?

Every time you fill up: If temperatures are above 30°F, add Diesel Kleen +Cetane Boost (silver bottle) for maximum performance.
