1. Reduce energy consumption;
	2. Conductive to dry start of equipment;
	3. Reduce the parts wear and friction noise;
	4. Improve the equipment utilization rate and prolong the equipment service life by 2-3 times;
	5. Effective reduce friction and reduce the operating temperature;
	6. Reduce friction by reducing the friction particles;
	7. The oil film formed by C690G is not easily affected by the temperature changes, so as to improve the equipment power; it can effectively reduce the wear during high-temperature operation.
