Features
1. Anti-high-temperature deposit property: Certified by API CF-4 standard, it can effectively prevent the formation of high-temperature carbon deposits and sludge on the top of engine pistons and valve guides, thus extending the engine's cleaning cycle.
2. Anti-wear protection: With the addition of anti-wear agents, it forms a stable oil film during high engine loads (such as heavy-load climbing), reducing wear on critical components like piston rings and crankshafts, and prolonging the engine's lifespan.
Application
Construction machinery: loaders, excavators, rollers (such as non-electronic injection models of brands like Komatsu and Caterpillar); agricultural machinery: tractors, harvesters and other agricultural equipment. Applicable environment: suitable for year-round use in temperate and subtropical regions, or for use in spring, summer and autumn in cold regions (in severely cold areas in winter, it is recommended to switch to a lower viscosity grade such as 5W40).

Grease Usage Notice
It should be noted that the CF-4 specification is a relatively basic grade of diesel engine oil. For diesel engines with electronic fuel injection systems that meet or exceed the National IV emission standards (such as those equipped with SCR and DPF systems), higher-grade engine oils (such as CI-4 or CJ-4) should be used to prevent malfunctions in the after-treatment system due to an incompatibility of the engine oil grade.
