Traction Control: Optional on some higher trims (TCS). 🔧 Maintenance Service Intervals Oil Change Recommendation: Every 3,000-5,000 miles or 3-6 months, especially under hard driving. Use of specific rotary engine oil (e.g., Idemitsu) is crucial. Spark Plug Replacement: Refer to manual for specific interval based on driving conditions, typically every 15,000-30,000 miles for platinum plugs. Crucial to use correct type for rotary. Timing Belt Equivalent: Rotary engines do not have timing belts. Apex seal and rotor housing wear are critical. Fluid Specifications Engine Oil Type: API SG or higher, SAE 10W-30 or 10W-40 recommended. Specific rotary oils are preferred. Capacity: 4.7 US quarts (4.5 liters) with filter change. Transmission Fluid Type: Manual: API GL-4 or GL-5 SAE 75W-90 synthetic gear oil. Automatic: Dexron II/III compatible fluid. Capacity: Approx. 2.3 US quarts (2.2 liters) for manual. Coolant Type: Mazda long-life coolant (blue) or equivalent mixture of distilled water and ethylene glycol. Capacity: 6.3 US quarts (6.0 liters). Known Issues Apex Seals: Degradation of apex seals leading to loss of compression and poor running. Proper lubrication and avoiding detonation are key. Turbocharger Reliability: Early twin-turbo systems can be prone to failure if not properly maintained or if subjected to excessive heat. Intercooler efficiency is crucial. Vacuum Lines: Cracked or leaking vacuum lines can cause boost leaks and drivability issues. Oil Consumption: Rotary engines inherently consume a small amount of oil, which is injected into the combustion chamber to lubricate seals. Excessive consumption indicates a problem. 📚 Vehicle History Brand Heritage Heritage: Mazda's lineage of innovative sports cars, building on the success of the RX-3, RX-7 SA22C, and FC3S generations.
