Classification
Product Performance:
■This product is formulated by blending hydrogenated base oil with a variety of functional additives, including extreme-pressure anti-wear agents, friction modifiers, antioxidant and anti-corrosion agents, as well as rust-inhibiting and anti-foaming agents. It exhibits excellent extreme-pressure performance, wear resistance and durability, rust and corrosion protection, thermal oxidation stability, and demulsification properties.
■The product meets the quality standards of the American Petroleum Institute API: GL-5.
■ Excellent extreme-pressure and anti-wear performance, effectively preventing scoring and wear on gear tooth surfaces under harsh conditions such as high-speed impact and high torque, with outstanding load-carrying capacity.
■ Outstanding thermal oxidation stability ensures that sludge and deposits are prevented from forming under high temperatures and heavy loads, keeping the tooth surfaces clean.
Scope of application:
It is suitable for lubricating gear-driven axles, drive shafts, and transmissions in various imported and domestically produced high-end passenger vehicles, heavy-duty trucks, and other vehicles operating under conditions of high-impact loads, high-speed low torque, and low-speed high torque—such as those found in railway locomotives.
Instructions for use:
■Please replace the oil according to the mileage and oil-change interval.
■ Do not mix with oil products from other brands at the same time, as this may affect the performance.
