Most diesel fuel offered in North America has a cetane rating of 40-45, but high performance diesel engines run best with a cetane number of 50 or higher. If the cetane number in your fuel is too low you could see excess white smoke, reduced power, increased oil sludge, decreased fuel economy and increased overall engine wear. Use CRC Concentrated Cetane Boost with every fill up for more complete combustion, fewer emissions, increased performance, faster acceleration and increased MPG. Use in all diesel engines. Compatible with biodiesel and all types of exhaust emission systems such as diesel particulate filters (DPFs.)
