DC101

Combustion Technologies DC101 is a powerful DEF system treatment designed to keep the DEF system clean, efficient, and reliable. One Bottle treats up to 20 gallons of DEF. DC101 breaks down and removes crystal buildup while preventing the possibility of new crystals from forming in the DEF tank, helping avoid costly downtime and repairs. It cleans and lubricates the entire DEF system, removes harmful sludge and bacteria, and lowers the DEF freeze point by up to 17 degrees for improved cold-weather performance. Additionally, DC101 reduces surface tension, improving return flow back to the tank and ensuring consistent, trouble-free operation.
