Your engine’s routine maintenance checklist—oil, filters, belts—sounds basic, but skipping any item can lead to major repairs. Here’s exactly what to do.
1. Oil: Changing vs. Lifetime Oils
- Conventional oil: Change every 3,000–5,000 mi.
- Synthetic oil: Change every 7,500–10,000 mi and lasts longer under heat.
Always use the grade your manufacturer specifies (e.g., 5W-30, 0W-20).
2. Oil Filter: Don’t Skip It
Each oil change should include a new filter to trap metal shavings and sludge. A clogged filter starves your engine of oil, risking catastrophic failure.
3. Air Filter: Engine Breathing
A dirty air filter reduces power and mileage. Inspect every 12,000 mi; replace every 15,000–30,000 mi. If you drive dusty roads, change it even sooner.
4. Serpentine and Timing Belts
- Serpentine belt: Powers alternator, water pump, A/C. Inspect every oil change; replace between 60,000–100,000 mi.
- Timing belt: Critical for engine timing—failure can wreck pistons. Replace per your service manual (usually 60,000–100,000 mi).
