Is a Major Maintenance at 40,000 Kilometers Necessary?

[DiEthan]

It is highly necessary to perform a major maintenance for your car at 40,000 kilometers, as it is crucial for the normal operation of the vehicle and should not be overlooked. More relevant information is as follows: 1. Major maintenance builds upon minor maintenance, and in addition to changing the engine oil, oil filter, air filter, and cabin air filter, it also requires replacing the fuel filter and the vehicle's brake fluid. The fuel filter's role is to provide clean fuel to the engine by filtering out water and impurities from the gasoline. This optimizes engine performance and provides protection for the engine. For automatic transmission models, transmission fluid may also need to be replaced, and for rear-wheel-drive models, differential fluid may also require replacement. 2. The car's battery should generally be replaced every two years. Typically, a vehicle will have traveled around 40,000 kilometers in two years, or even if it hasn't reached that mileage, the battery should be checked for any power loss.
