Good detergency and dispersancy effectively keep the piston clean, prevent piston abnormal wear;

Low ash content, high heat load environment, minimizing the deposit,

Reduce the wear of engine air intake valve and exhaust valve, to prevent early ignition engines;

Good oxidation stability, effectively reduce the oxidation products such as sludge formation, inhibit the lubrication

Oil viscosity and the acid value growth, extend the oil change period, suitable for all kinds of natural gas vehicle.
