Critical for rotary engines. Air Filter: Inspect every 7,500 miles (12,000 km), replace as needed or annually. Spark Plugs: Replace every 15,000-30,000 miles (24,000-48,000 km), depending on type (standard vs. platinum). Apex seals also require inspection/periodic replacement. Coolant Flush: Every 30,000 miles (48,000 km) or 2 years. Fluid Specifications Engine Oil: API SG or SH, SAE 10W-30 or 10W-40 (check owner's manual for specific recommendations). Rotary engines require pre-mix oil injection or specific oil for oil metering injection systems. Coolant: Ethylene glycol-based antifreeze. 50/50 mix with distilled water. Known Issues Rotary Engine Wear: Apex seal wear, eccentric shaft seal leaks, oil seal degradation leading to low compression. Oil Consumption: Higher than piston engines; normal consumption should be monitored. Excessive consumption indicates issues. Fuel Injectors: Clogging or failure, particularly in higher mileage vehicles. Leading Armature Failure: Can occur with prolonged high-revving or inadequate lubrication. Suspension Bushings: Wear and tear on rubber bushings leading to degraded handling and noise. 📚 Vehicle History Brand Heritage Mazda Rotary: Mazda's pioneering history with the rotary engine, starting with the Cosmo.
