Features
Quality Grade (CF-4): Compliant with API CF-4 standards, it is specially designed for naturally aspirated and turbocharged diesel engines produced before 1994. It can effectively control the formation of high-temperature carbon deposits and sludge, reduce piston ring wear, and meet the basic anti-wear and cleaning requirements of non-injection equipment such as old heavy trucks, loaders, diesel generators, and tractors.
Application
1. Equipment that requires high viscosity to maintain high-temperature lubricity in summer outdoor operations or high-temperature environments (such as southern summers, mining areas, construction sites).
2. Equipment that operates under long-term heavy loads, low speeds, and high loads (such as short-distance heavy-load transport trucks, construction machinery frequently starting and stopping within construction sites).
3. Conventional operation scenarios where the ambient temperature is within the range of -20℃ to 40℃, without the need to deal with extreme cold (below -25℃) or extreme heat (above 50℃).

Grease Usage Notice
This product is strictly prohibited for use in electronic fuel injection or high-specification engines: Modern electronic fuel injection diesel engines (such as models meeting or exceeding the National IV emission standards) have higher requirements for environmental protection, sulfur resistance, and anti-wear. The CF-4 specification is not compatible. Forcing its use may lead to clogging of the fuel injectors, failure of the three-way catalytic converter, and even engine cylinder pulling.
