Manufacturer-Recommended Service Schedule
The manufacturer-recommended maintenance schedule for the 2004 Mazda Rx-8 is shown above. Keeping up with these service intervals prevents premature wear, maintains fuel economy, and protects your powertrain warranty.
The most critical intervals are engine oil changes (typically every 5,000–10,000 miles for full synthetic), tire rotation (every 5,000–7,500 miles), and brake fluid (every 2–3 years). Always verify intervals against your owner's manual — the schedule varies by driving conditions.
