Keeping up with maintenance is the single best thing any vehicle owner can do to avoid expensive repairs. This checklist covers every major service item by interval — use it to stay ahead of failures before they happen.

🔧 Every 3,000–5,000 Miles

  • Engine oil and filter change
  • Tire pressure check (including spare)
  • Visual inspection: lights, fluid leaks
  • Windshield washer fluid top-off

🔧 Every 15,000–20,000 Miles

  • Tire rotation and balance
  • Air filter inspection (engine and cabin)
  • Brake inspection (pads, rotors, fluid level)
  • Battery terminals clean and inspect
  • Wiper blade inspection

🔧 Every 30,000 Miles

  • Transmission fluid service (check interval for your vehicle)
  • Coolant flush (check interval)
  • Fuel filter replacement (if serviceable)
  • Spark plug inspection (some vehicles 60k–100k)
  • PCV valve replacement
  • Brake fluid replacement

🔧 Every 60,000–100,000 Miles

  • Timing belt / timing chain inspection
  • Spark plugs (iridium/platinum — check manufacturer spec)
  • Serpentine belt and idler pulleys
  • Wheel bearing inspection
  • Differential fluid service (AWD/4WD)
  • Transfer case fluid service (if applicable)

🔧 Annual Inspections (Regardless of Mileage)

  • Battery load test
  • Exhaust system inspection
  • Suspension and steering components
  • CV axle boots and joints (front-wheel drive)
  • Fuel line and vacuum hose inspection

💡 Pro Tip: Always follow your vehicle's specific maintenance schedule in the owner's manual. The intervals above are general guidelines — severe service (towing, extreme temperatures, frequent short trips) requires more frequent service.

Why This Matters

Deferred maintenance is the #1 cause of premature vehicle failure. A $15 oil change skipped twice often leads to a $5,000 engine replacement. A missed transmission service leads to a $3,500 rebuild. The math is simple: maintain it, or pay for it later.
