## Description

20+ Cetane Boost is an EPA approved concentrated diesel fuel conditioner designed for today's low sulfur and off-road diesel fuels. This product increases cetane ratings in any diesel fuel while lowering the gel point to 35 degrees below zero when mixed 16 oz. to 100 gallons of diesel fuel. 20+ Cetane Boost also includes a highly desirable lubricity additive to protect fuel systems and internal engine parts when using low sulfur diesel fuel. This product will clean and lubricate fuel system components. 20+ Cetane Boost can increase the percentage of diesel fuel burned in the combustion chamber, thereby increasing power and fuel economy at the same time. Many users report a 5 percent - 10 percent increase in mileage which means 20+ Cetane Boost can pay for itself.
