Fleet master CK-4 Extreme 15W/40 is an API CK-4 heavy-duty diesel engine oil formulated using the latest synthetic technology base oils for use in severe-duty high-speed four-stroke diesel engines with DPF, cooled EGR and other exhaust treatment systems, both turbocharged and normally aspirated. It is designed to offer greater durability and protection due to its increased shear stability and reduced oxidative thickening, abrasive wear bore polishing and piston deposits.
Benefits
- Increased shear stability
- Reduced oxidative thickening for increased viscosity stability
- Lower piston deposits
- Protection against particulate filter blocking and soot-related viscosity increase
- Increased wear protection due to less abrasive wear and bore polishing
- Better fuel economy
- Increased resistance to aeration
- Protection against catalyst poisoning
- Higher levels of protection and performance compared to API CJ-4
Applications
- 2017 model vehicles as well as those requiring Euro VI emission standards
- Backward compatible with engines requiring CJ-4, CI-4 Plus, CI-4 and CH-4
