VISCOSITY CONTROL
Resists oxidation and the thickening effects of soot contamination
Retains viscosity after high-temperature service for added engine protection and increased fuel economy
Provides up to 66 percent less oil consumption2
2Than required by the API CK-4 standard in the Caterpillar-1N oil consumption test
Reduces Oil Consumption
Heavy-Duty Synthetic Diesel Oil provides up to 66% less oil consumption.L
EXCELS IN EXTREME TEMPERATURES
Provides outstanding protection and performance in hot and cold temperature extremes
Delivers improved heat and oxidation resistance compared to conventional diesel oils
Flows dependably in cold temperatures for easier startup and improved engine protection
