Mazda MX-5 Maintenance Schedule

Planning to work on your Mazda MX 5 or Mazda Miata? These are the minimum intervals recommended by us for MX-5s driven daily. If you wish to keep your MX5 roadster in peak condition at all times, you may wish to perform some of these procedures more often. We encourage frequent maintenance, since it enhances the efficiency, performance and resale value of your MX-5. Don't forget to check out our online manuals or the Haynes Mazda MX-5 printed manual to learn more about working on your own roadster.

Do you live in a harsh climate, where it's particularly dusty or by the sea? Maybe you frequently drive your MX-5 at slow speeds (idling in traffic) or on short journeys? If so, more frequent maintenance intervals are recommended.
