Product overview
Outstanding engine protection
- Conventional oils tend to oxidize at high temperatures, leading to the buildup of sludge and varnish. For extended drain intervals, oxidation resistance is crucial. Cenex oils meet this demand, exceeding the most grueling oxidation test required by Mack for API CK-4, delivering virtually no viscosity change in the Mack T-13 test. Engineered to provide superior viscosity retention and shear resistance, Cenex diesel engine oils outperform conventional oils. Our high-performing diesel engine oils feature industry-leading polymer technologies to extend oil durability for longer oil life and engine protection.
Exceptional engine cleanliness
Cenex advanced formulas are engineered with Wear Saver Technology® to provide an additional level of protection for engine parts under the most extreme conditions. These oils disperse conventional and EGR soot into finer particles that are far less abrasive on engine parts. All formulations are proven to provide superior piston cleanliness at 500,000 miles.
Enhanced corrosion protection for reduced wear
Preventing corrosive bearing wear, which results from acid formation in the engine, is crucial for extended drain protection. Cenex heavy-duty diesel engine oils provide a high and durable Total Base Number (TBN), safeguarding your equipment investment.
