At how many kilometers does a car generally require a major maintenance?

[SanMadelyn]

Generally, a vehicle requires a major maintenance when it reaches 30,000 kilometers. This involves replacing components such as engine oil and oil filter, air filter, fuel filter, power steering fluid, and spark plugs. Additional information: Dry air filter: Most car engines use a dry air filter with a paper filter element that is lightweight, low-cost, easy to replace, and highly efficient. It should be cleaned every 5,000 kilometers. When cleaning, remove the filter element and gently tap the end face, then use compressed air to blow from the inside out to remove dust. Avoid washing with gasoline or water. Oil filter: The air filter must be replaced every 25,000 kilometers. As for the oil filter, most car engines use a spin-on oil filter, which is a disposable, non-cleanable filter. When changing the lubricating oil, the oil filter must also be replaced; otherwise, it will affect the quality of the lubricating oil. The replacement cycle for engine oil and oil filter is generally also 5,000 kilometers.
