New energy vehicle Gear Oil how often to replace!

New energy vehicles refer to the use of unconventional vehicle fuel as a power source (or the use of conventional vehicle fuel, the use of new on-board power devices), the integration of vehicle power control and drive advanced technology, the formation of advanced technical principles, with new technology, new structure of the car.

New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles.

New energy vehicles than fuel vehicles, less is the engine, transmission, etc., so such as oil, filter, transmission oil, etc., naturally do not need to add and replace, but electric vehicles have electric motors, need regular replacement of gear oil to lubricated, and electric vehicles for lightweight, the use of gear oil and gasoline cars will be different.

How many kilometers of electric vehicle to change the gear oil?

For different brands of electric vehicles, the number of gear oil changes is not necessarily the same. The shortest is 20,000 kilometers and the longest is 40,000 kilometers. In general, it is best to change the gear oil once a year.

Compared with the traditional fuel vehicle transmission has multiple gears to switch, the new energy vehicle transmission has only one gear, and the speed and torque are completely controlled by the motor output power. Therefore, the parts used in new energy are more demanding than traditional fuel vehicles, and the corresponding maintenance is also different, mainly by replacing the gear oil to maintain the service life of the internal parts of the transmission.

Usually, the transmission of the new energy car uses a medium load extreme pressure anti-wear gear oil, the recommended grade is 75W-90 GL-4. Some car manufacturers recommend the use of life-long maintenance free oil, not recommended here. Under general conditions of use, the first replacement gear oil cycle is 3 months /5000Km, and the subsequent maintenance is replaced every two years /20000Km; For harsh use conditions, the first replacement of gear oil cycle is also 3 months /5000Km, and subsequent maintenance needs to be adjusted to replace once a year /10000Km.

When replacing the gear oil, it is also necessary to clean up the dust, impurities and mud near the air valve and oil seal, and check whether the related plug is loose, which is conducive to extending the service life of the transmission.
