With the rise of consumption level, almost every household now has its own car, which can meet the needs of all aspects of the car while being convenient. However, the cost of maintenance also makes many young migrant workers discouraged from buying a car.
Not to mention the cost of maintenance, just the recent soaring "sky-high oil" makes people want to drop four rounds, change two rounds, there are many people on the Internet laughing, plus four times oil can buy a small electric. Although the oil price can not be changed, but the maintenance can still do less to spend money, maintenance on a lot of knowledge, quickly with the editor to see, how to maintain the "moisture" in the car ~
The general owner can distinguish whether the gear oil of the car should be replaced according to the feeling of daily hanging gear, and it is completely no problem to run about 20,000 kilometers after replacing the gear oil, but more than 20,000 kilometers should be paid attention to. If the gear is smooth, the noise of the gearbox does not change, you can run with confidence, but if you feel that the noise of the gear becomes larger, you must replace the gear oil in time at this time, otherwise it will aggravate the friction of the gear, so that your car will enter the overhaul period in advance.
However, the gear oil does not need to be replaced frequently, generally 60,000 kilometers or 2-3 years to replace. Avoid losing lubrication for too long a long time, causing serious wear and tear on the gears in the gearbox, abnormal wear of the gears due to incorrect transmission gear selection during the driving process, or abnormally harsh driving conditions (wading), which will lead to deterioration of the gear oil inside the transmission or iron filings. At this time, we need to change the oil to ensure that the transmission continues to use normally.
At present, the manual transmission gear oil is better: the general GL-4, GL-5 grade 85W/90, 85W/140, in theory, the maximum replacement mileage of these two gear oils is 60,000 kilometers; GL-4, GL-5's 75W/90 is a fully synthetic gear oil, much better than 85W/90, 85W/140, but the price is also quite high.
The owner's proficiency in vehicle operation, the road conditions of the vehicle, the mileage driven over a period of time, whether it is often super high-speed racing, etc., these driving habits determine the actual cycle and mileage of the gear oil replacement. In addition, there is a so-called good gear oil manual transmission that can be replaced for life and absolutely cannot be adopted! Each brand is different and cannot be generalized.
