Is Car Maintenance Based on Time or Mileage?

[DiAshley]

Car maintenance considers both time and mileage. Car maintenance refers to the regular inspection, cleaning, replenishment, lubrication, adjustment, or replacement of parts related to the vehicle. The scope of car maintenance mainly includes: the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. The purpose of car maintenance is to eliminate potential hazards and extend the service life of the vehicle. Car maintenance can be divided into minor maintenance and major maintenance. The timing of minor maintenance is determined based on the type of oil used, while major maintenance can be referenced according to the maintenance manual provided by the manufacturer when purchasing the car.

As a frequent driver, I believe car maintenance shouldn't focus on just one factor - both time and mileage need attention. Based on my experience, the manual specifies maintenance every 5,000 km or 6 months, whichever comes first. Last time I only drove 3,000 km but stretched it to seven months, and during inspection the mechanic found the engine oil had thickened. He explained prolonged parking causes fluid degradation that damages the engine. Conversely, when I do lots of highway driving and exceed the mileage limit in three months, I need early oil and air filter changes too. Neglecting time intervals risks component aging like brake fluid absorbing moisture and failing, while ignoring mileage accelerates wear. I keep track of maintenance dates and odometer readings to avoid headaches and save on repairs.

From my observations helping friends with car repairs, maintenance standards always follow whichever comes first: time or mileage. For example, with oil changes, if the car sits idle for too long, the oil oxidizes and thickens after six months, affecting lubrication; if used daily for commuting, maintenance should be scheduled once the mileage approaches the limit. Other components like tires and batteries rely more on time factors—replace them when they age. Remember, the vehicle manual is the gold standard; don’t try to cut corners to save money. Long-term neglect of time-based maintenance may lead to oil leaks or system failures, while ignoring mileage can cause severe engine wear. Safe driving relies on prevention, and regular professional inspections can extend your car’s lifespan.

I've only owned my car for two years and just realized that maintenance isn't a one-size-fits-all approach. The manual recommends servicing every 7,500 kilometers or six months, whichever comes first. I don't drive much, but when the time comes, I make sure to go promptly to avoid fluid degradation issues. If you drive more frequently, you should also act when the mileage limit is reached. Make it a habit and set reminders.
