Diesel Engine Oil
Truck Plus API CI-4/SL 15W40
Lubrezool Truck Plus API CI-4/SL 15W40 is designed for heavy-duty diesel engines and to meet exhaust emission standards. It is especially effective at sustaining emission control system durability where particulate filters and other advanced systems are used. Optimum protection is provided for control of catalyst poisoning, particulate filter blocking, engine wear, piston deposits, low- and high-temperature stability, soot handling properties, oxidative thickening, foaming, and viscosity loss due to shear.
- Ensures long engine life
- Provides good lubrication for frequent stop-start conditions
- Offers superior wear protection
- Keeps piston and crankcase clean
- Molybdenum metal technology to protect against engine wear and tear
Applications
Suitable for turbocharged and naturally aspirated diesel engines used in on-highway and off-highway applications, including those fitted with EGR systems. The combination of base oils and the latest advanced additive technology meets the service requirements of API Engine Service Classification API CI-4/SL.
