Should Car Maintenance Be Based on Time or Mileage?

Car maintenance can be based on either time or mileage, whichever comes first. Common car maintenance items include: 1. Replacing engine oil, oil filter, air filter, cabin air filter, fuel filter, transmission fluid, and engine belts; 2. Inspecting spark plugs, tires, and braking systems; 3. Cleaning throttle bodies and fuel injectors; 4. Topping up brake fluid. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain components of a vehicle. Its purpose is to maintain a clean appearance, ensure normal technical conditions of the vehicle, eliminate potential hazards to prevent failures, slow down the deterioration process of parts, and extend the service life.

During my car maintenance process, I found that both time and mileage need attention, and maintenance should be done whichever comes first. Car manufacturers usually specify in the manual every six months or 5,000 kilometers, which is not arbitrarily set. Over time, engine oil oxidizes and deteriorates, and internal parts may rust in humid climates; high mileage accelerates engine wear. I recommend regularly checking the oil level and color. If you drive less, follow the time-based maintenance to avoid potential issues; if you drive more, keep a close eye on the mileage. Additionally, pay attention to seasonal changes—high summer temperatures can thin the oil, while winter cold affects lubrication. Safety first, as delays may lead to expensive repairs. Developing a habit of recording and using a mobile app for reminders can save you trouble.

As a novice driver who has owned a car for less than two years, I used to struggle with maintenance standards. The mechanic explained that both indicators are important, and maintenance should be performed based on whichever comes first according to the manual. Engine oil degrades over time, causing viscosity changes, and aggressive driving increases wear. Although I don't drive much, I insist on getting a check-up every six months to save money and prevent potential issues. Last time, when the mileage slightly exceeded the limit, the engine noise became noticeably louder, but it smoothed out after an immediate oil change. Regular maintenance saves more money than emergency repairs, and setting phone reminders makes it easier to manage.
