Follow Mazda’s Schedule to Boost Value

You keep your 2020 Mazda CX-3 value high when you follow Mazda’s service schedule and document every visit. Clean records earn 2 to 5 percent higher offers. They also help your car sell faster. Plan $350 to $500 per year in routine care if you drive 12,000 miles. The CX-3 uses 0W-20 synthetic oil and iridium spark plugs. These allow longer intervals. Stick to the schedule anyway.

Skip basics and you risk uneven tire wear, early brake jobs, or engine problems. Buyers spot these issues. They worry and offer less.

Practical Tips

  • Use OE-quality parts. Keep all work orders. Buyers like brand-name or equal parts.
  • Save every receipt. Make a digital folder and a paper one. Hand them to buyers.
  • Check tire pressure monthly. Set it to the door-jamb spec. Even wear looks good and drives well.
  • Wash and wax twice a year. Fix paint chips fast to stop rust. It makes a strong first impression.
  • Fix any warning light right away. Small fixes now save big repairs later.
  • Get a pre-sale inspection 60 to 90 days before you list. Fix minor issues in time.
