Gearbox is the most frequent contact parts of drivers, the smooth use will greatly affect the pleasure of driving, so the comfort, flexible operation and long-term stability of gearbox is very important experience, and as the guardian of gearbox - gearbox oil plays an important role.
In all transmission product, manual transmissions and automatic transmission are that two most common types, and the lubricating oils they use are respectively refer to as manual transmission fluids, MTF for short and Automatic Transmission Fluid (ATF). But how do you usually select specifications for transmission oil? What are the categories? What are the requirements for the lubricating oil? What are the precautions in use? Do you know all of this? Quasi-German lubricating oil dispenser small book to answer for everyone.
Although there are more and more automatic gears now, the ATF is not discussed here because the early automatic transmission is directly using engine oil, there is no fixed standard, there is more OEM standard, the ATF is not discussed here, the MTF is mainly discussed today.
MTF can be divided into 11 types according to viscosity: 70W, 75W, 80W, 85W, 80, 85, 90, 110, 140, 190, 250. With the development of technology, the viscosity of MTF oil is becoming more and more low viscosity and multi-grade oil, which can adapt to the environment of cross-region and large temperature difference. The specifications issued according to API can be divided into: API GL-4 and API MT-1, which is closely related to the development of MTF
