What the experts say…


Bruce Ellis Prestone“Industry is powered by heavy duty diesel engines, but did you know the cooling system is responsible for 40% of all HD engine downtime? In business we don’t like downtime as it increases our operating costs.

At Prestone we’ve developed a unique, patented OAT based Extended Service Life Heavy Duty coolant to reduce routine and unscheduled maintenance.”

Bruce Ellis, Global Technical Director

Prestone Command HD reduces downtime by offering superior protection for every component in the cooling system and for up to 600,000 miles (100,000 km) or 12,000 hours for off road/static engines. It protects against liner pitting and contains no silicates, so will not cause silicate gels to block the radiator. Based on OAT technology, Prestone Command HD is also free from nitrates, nitrites, amine and phosphate.

Prestone Command HD Coolant/Antifreeze is also compatible with all OAT Extended Life HD Antifreeze/Coolant, and can be used by any diesel engine in any industry.

The formula is available as Ready to Use 50/50 and Concentrated.

Add to any OAT extended life coolant/antifreeze. Flush and fill for full extended service life protection.
