2008 Mazda RX-8 Mileage Danger Zones
The mileage windows when the 2008 Mazda RX-8 most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Ignition Check Point
At this mileage, ignition components (coil packs, plugs, wires) are often due for inspection or replacement to prevent misfires and carbon buildup, which directly impact engine longevity.
Engine Health Critical Assessment
This mileage range is where many Renesis engines begin to show signs of compression loss due to apex seal wear or carbon buildup. A compression test is absolutely vital here.
High Probability Engine Rebuild/Replacement
Few Renesis engines make it significantly past 90,000 miles without a rebuild or replacement, especially if not perfectly maintained from day one. Expect significant wear at this point.
Extreme Risk Zone
An RX-8 reaching this mileage likely has had at least one engine rebuild or replacement. Any original engine at this point is a ticking time bomb, and even rebuilt engines require continuous vigilance.
2008 Mazda RX-8 Ownership Cost Outlook
What it typically costs to keep the 2008 Mazda RX-8 on the road. Full 5-year cost-of-ownership projection and major-failure-risk forecast are in the report.
Annual Maintenance

Moderate Repairs
$1,000-2,500 occasionally (suspension, catalytic converter, transmission work)
How Long Does the 2008 Mazda RX-8 Last?
Any RX-8 approaching 60,000 miles should be treated with extreme caution and subjected to a thorough, rotary-specific compression test. High mileage examples (90,000+) are likely on their second or third engine.
