Mazda RX-8 2007

🚨 What to check before buying

Overall risk score: 10/10

Serious risks

• Apex seal failure: Rotary apex seals wear and eventually fail. This is inherent to the design. Most engines need rebuild at 80-120k km. Engine rebuild or replacement is required.
• High oil consumption (by design): Rotary engines inject oil into the combustion chamber by design. Check oil level frequently.
• Flooding (cold start): Engine can flood if shut off before reaching operating temperature. Must be fully warmed up before turning off.
• Catalytic converter failure: High oil consumption and incomplete combustion destroy cats.
• Car is 19 years old — expect age-related wear: rubber seals, bushings, water pump, AC compressor
• Higher mileage (154,600 km) — check for timing system condition, turbo health, and suspension wear

Additional notes

• 13B-MSP_RENESIS engine has known reliability problems — assess carefully
• ⚠️ Mazda RX-8 Renesis rotary: apex seal failure is WHEN not IF. ~50-80k km between rebuilds. Burns oil BY DESIGN (1L per 3000km). Must be warmed up fully every time. Never turn off cold. Flooding kills it. Compression test MANDATORY before buying. Rebuild costs €2,000-5,000.
• Vehicle is 15+ years old. Age-related issues: rubber seals/hoses degrade, electrical connectors corrode, suspension bushings wear. Not specific to any engine, but expect €500-1,500/year in age-related maintenance beyond normal service items.
• HIGH RISK: Mazda RX-8 rotary engine has inherently limited lifespan. Apex seals wear and most engines need rebuild at 80-120k km (€2,500-6,000). Also: starts poorly when cold (flooding risk), consumes oil BY DESIGN (1L per 3000km), and destroys catalytic converters. Compression test is ESSENTIAL before purchase. Buy only if you understand and accept rotary ownership costs.
