  Midwinter, what automobile engine oil with the use of safety-related owners, Quality and Technical Supervision sampling results show that 95% of the lubricating oil can rest assured. Provincial Quality and Technical Supervision Organization on the inspection unit of automotive lubricants, corrugated boxes and packing bag three kinds of products for the provincial supervision. In the sample of 36 vehicle lubricants production of 40 batches of products, qualified 38 batches of products quality sample pass rate of 95%. Provincial Quality Supervision Bureau, responsible person, the main unqualified items substandard lubricant products for the low-temperature dynamic viscosity and low viscosity required for pumping.

  Low dynamic viscosity is a measure of the lubricating oil at a low temperature, high shear rate conditions measured the size of the internal friction, piston rings and engine lubricants to reflect the cold flow properties of parts of the cylinder liner, the use of substandard products may cause Cars can not start in cold weather and the engine damage.

  Pumping capacity is low viscosity engine friction surface oil at low temperatures to the oil pump, it is winter in one of the important indicators of quality lubricants and multi-grade oil, but also by the viscosity of the lubricant is an important basis for classification, the project failed to use the product easy to make serious damage to the vehicle.
