Features
Outstanding oxidation stability: The fully synthetic base oil combined with high-efficiency additives can resist the oxidation and deterioration of engine oil caused by high temperatures (such as the temperature at the top of the engine piston reaching over 300℃), extending the oil change cycle. The oil change mileage of most products can reach 100,000 to 150,000 kilometers (about 50,000 kilometers for ordinary mineral oil). Strong anti-wear protection: By optimizing the anti-wear agent formula, a stable oil film is formed during high engine load (such as heavy-load climbing), reducing the wear of key components such as pistons, crankshafts, and camshafts, meeting the API CK-4 requirement of "reducing engine wear rate by 15%".
Application
1. Compatible engine types:
- Heavy-duty diesel engines meeting National V and VI emission standards (such as Weichai WP13, Yuchai YC6K, Cummins X12, etc.);
- Engines equipped with EGR, DPF, and SCR (Selective Catalytic Reduction) after-treatment systems;
- High-end diesel equipment requiring "low-viscosity, long-life" engine oil (such as imported construction machinery and cold chain logistics trucks).

Grease Usage Notice
Notes on Use
1. Follow the oil change standards: Regularly check the oil level and quality as required by the equipment manual (such as through oil sample analysis to test viscosity and metal wear particle content), and do not rely solely on mileage. This prevents the oil from prematurely failing due to poor fuel quality or harsh working conditions.
2. Avoid mixing: Do not mix with other specifications of oil (such as API CJ-4, CI-4 or different viscosity 10W-40), otherwise it may disrupt the additive balance and lead to performance degradation.
3. Storage requirements: Seal and store in a cool and dry place, away from direct sunlight or high-temperature environments to prevent oxidation. After opening, it is recommended to use up within one year to avoid water or impurities from mixing in.
