Definitions

  • the present invention relates to a lubricating oil composition, and more particularly to a general lubricating oil composition for a vehicle transmission system, which belongs to the technical field of lubricating oils and lubricating oil additives.
  • the vehicle transmission system mainly includes the manual transmission system and the drive system.
  • the manual transmission system and the drive system require special lubricating oil for lubrication.
  • the manual transmission is lubricated with MTF, and the drive system adopts API GL-5 or API GL- 4 vehicle gear oil to lubricate.
  • Passenger car manual transmission oil has its own standards for all major automobile manufacturers. It is standardized to pass the SSP-180 synchronizer manual transmission cycle gantry; the highest standard for commercial vehicle manual transmission oil is API MT-1. Through the MACK cycle bench test; the highest standard for drive axle oil is API GL-5, which requires four bench tests of CRC L-42, L-37, L-60, and L-33.
