Connectivity Bluetooth Usb: Not available in original factory configuration; aftermarket solutions common. 🔧 Maintenance Service Intervals Oil Change: Every 3,000 - 5,000 miles or 6 months, or as per manual, using appropriate synthetic oil. Spark Plugs: Rotary specific plugs, check intervals in manual (typically around 30,000 miles but depends on type). Timing Belt Chain: Rotary engines do not have timing belts; they have a timing chain/gear system which is more durable but requires inspection. Fluid Specifications Engine Oil: API SG or higher, viscosity typically 10W-30 or 5W-30 synthetic. Check manual for precise spec. Coolant: Mazda long-life coolant or equivalent (50/50 mix with distilled water). Transmission Fluid: GL-4 gear oil (e.g., 75W-90) for manual transmission. ATF Type T-IV or equivalent for automatic. Check manual. Known Issues Apex Seals: Wear or failure of apex seals is a common concern with high mileage rotary engines, leading to compression loss. Sequential Turbo System: Failures in the solenoids or actuators controlling the twin-turbo sequence can impact power delivery. Oil Consumption: Rotary engines naturally consume oil as part of their lubrication system; consistent checking and topping up is crucial. Catalytic Converter: Can be susceptible to failure if the engine is not maintained properly, leading to performance issues. 📚 Vehicle History Brand Heritage Mazda Sports Legacy: Mazda has a long history with rotary engines, notably with the Cosmo and the legendary RX-7 and RX-8 models.
