Diesel Super Coolant

Hy-per Lube Diesel Super Coolant is specifically formulated to improve the cooling ability of modern turbocharged/intercooled diesel engines. The extra heat developed by turbochargers, and the addition of EGR & Oil Coolers, places extremely heavy demands on diesel engine coolant. Diesel Super Coolant enhances coolant heat transfer, allowing the cooling system to dissipate heat more effectively, reducing engine temperatures up to 30°F and helping protect against overheating.  Lower engine Cylinder Head Temperatures (CHT) enhance turbo engine efficiency, providing better fuel economy, power and performance.  This results in average fuel economy increases of 1-2%, and torque increases of 2-3%.

Hy-per Lube Diesel Super Coolant also acts as a complete Supplemental Coolant Additive (SCA), as it provides 100% protection from cavitation, corrosion, and electrolysis. Reserve alkalinity continuously buffers pH to safe levels and protects wet sleeve cylinder liners from cavitation erosion.  Compatible with ALL types of diesel engine coolant and SCA additives/filters.
