Use high viscosity index fully synthetic base oil to ensure stable oil film strength under high temperature and high pressure environment, and reduce viscosity drop caused by shear.
Effectively prevent oil deterioration, extend oil change cycle, and reduce maintenance costs.
High-efficiency cleaning and dispersing technology effectively inhibits carbon deposits and sludge, keeps the engine clean and reduces wear.
Long-lasting antioxidant formula prevents oil deterioration caused by high-temperature oxidation, ensuring long-term and efficient operation of the engine.
Nano-level anti-wear additives form a high-strength protective film on key parts such as cylinder liners, piston rings, and bearings, greatly reducing metal-to-metal friction.
Suitable for modern diesel engines such as turbochargers and high-pressure common rails, reducing wear and improving engine durability.
Low-friction formula reduces internal resistance, improves combustion efficiency, and helps save 3%-5% of fuel.
Suitable for long-distance transportation, construction machinery, heavy-duty trucks and other scenarios, reducing comprehensive operating costs.
Excellent ultra-low temperature fluidity, ensuring fast pumping in -30°C environment, reducing cold start wear.
Optimize seal compatibility, prevent oil seal hardening or swelling, and extend the life of rubber parts.
This product strictly follows international authoritative certification, is suitable for various high-end diesel engines, and meets the following original factory specifications:
