What needs to be replaced for a car with 30,000 kilometers in three years?

[StKyle]

For a car with 30,000 kilometers in three years, the main replacements include engine oil, oil filter, air filter, and cabin air filter. Additionally, if the vehicle has an external fuel filter, it may be time to replace it at around 30,000 kilometers, while an internal fuel filter does not require any attention. Detailed introduction to 30,000-kilometer maintenance: Since 30,000 kilometers is still 10,000 kilometers away from 40,000 kilometers, many fluids are not yet due for replacement. Therefore, the maintenance at 30,000 kilometers is still considered minor, with not many items needing replacement. Completing the maintenance tasks: The final step at 30,000 kilometers is to perform a cross-rotation of the tires (front to back). Additionally, check all the vehicle's fluids. Once all fluid levels are confirmed to be normal, the maintenance is complete.
