Car Maintenance Schedule: What to Replace and When
Keeping up with scheduled maintenance extends vehicle life and prevents expensive breakdowns. This guide shows the recommended replacement intervals for all key consumables based on your current mileage.
Engine oil is the most critical item — conventional oil should be changed every 3,000–5,000 miles and synthetic every 5,000–7,500 miles. The timing belt is the highest-stakes item: a snapped timing belt causes catastrophic engine damage. Most manufacturers recommend replacing it every 60,000–100,000 miles or every 5–7 years, whichever comes first.
Brake pads are a safety-critical wear item. You'll typically hear squealing or grinding when they're worn. At 25,000–65,000 miles depending on driving habits, they need inspection and often replacement.
Frequently Asked Questions
Conventional oil: every 3,000–5,000 miles. Synthetic oil: every 5,000–7,500 miles. Always follow your owner's manual — modern engines are more forgiving, but fresh oil is the single best thing you can do for longevity.
If the timing belt snaps, pistons and valves collide, causing catastrophic engine failure costing $3,000–$8,000 to repair. It's one of the most expensive maintenance failures to ignore.
Listen for squealing (wear indicator touching rotor) or grinding (metal-on-metal contact). Feel for vibration under braking. Don't ignore these signs — worn brakes directly compromise your stopping distance.
