What is the difference between ZF MT and MT+ transmission oil?
1 Answers
The differences between ZF MT and ZF MT+ transmission oil are as follows: 1. Different boiling points: The boiling point of ZF MT is greater than or equal to 205°C, while the boiling point of ZF MT+ is greater than or equal to 230°C. If the boiling point of the transmission oil is too low, it can easily vaporize in the system, causing vapor lock, which may lead to delayed braking or even brake failure. 2. Different types: ZF MT is an alcohol-ether type, and its water content gradually increases during use or storage. Since the boiling point of the transmission oil decreases as the water content increases, its braking performance will decline accordingly. ZF MT+ is an ester type, which can decompose the absorbed water, thereby slowing down the decrease in boiling point caused by water absorption. Therefore, the performance of the ester type is better than that of the alcohol-ether type.
