At how many kilometers does a car require major maintenance?

[Kingston]

Generally, vehicles require a major maintenance service after traveling 30,000 kilometers. This involves replacing components such as engine oil, oil filter, air filter, fuel filter, power steering fluid, and spark plugs. Below is a partial introduction to major car maintenance: 1. Major maintenance builds upon minor maintenance, adding the replacement of air and fuel filters to the standard oil and oil filter change. These two filters serve to remove dust from the air and impurities from the fuel. 2. Most car engines utilize a dry-type air cleaner with a paper filter element, which is lightweight, low-cost, easy to replace, and highly efficient. It typically requires cleaning every 5,000 kilometers. 3. During routine car maintenance, technicians will perform additional inspections based on the vehicle's specific condition and may include other maintenance items, such as inspection and cleaning of engine-related systems, wheel alignment checks, and inspection of various fastening components.
