FLEET CHARGE HYBRID BLUE Coolant/Antifreeze is a Hybrid Organic Acid Technology (HOAT)
Extended Service Interval (ESI) coolant/antifreeze with a phosphate-borate dual buffer system, nitrite and a low silicate level. It is formulated for use in heavy duty engines, regardless of fuel type, as well as in automobile and light duty applications. Its characteristic blue color identifies it as a hybrid coolant.
FLEET CHARGE HYBRID BLUE Coolant/Antifreeze is designed to work with liquid and slow-release Supplemental Coolant Additives (SCAs) available in the market today, simplifying coolant maintenance while extending service intervals up to 150,000 miles (260,000 km) or 4000 hours of operation.†
