Oil Change:
Every 3,000-5,000 miles or 3-6 months, depending on driving conditions. Consult manual for specific rotary oil recommendations.
Air Filter:
Inspect every 15,000 miles, replace as needed or every 30,000 miles.
Spark Plugs:
Platinum-tipped plugs recommended, replace every 30,000-60,000 miles. Specific rotary plug types are crucial.
Coolant Flush:
Every 2-3 years or 30,000-50,000 miles.
Engine Oil:
API SG/SH or higher, Viscosity SAE 10W-30 or 10W-40 recommended (check manual for specific rotary engine oil requirements, often a specific blend is advised).
Transmission Fluid Manual:
API GL-4 or GL-5, SAE 75W-90 or 80W-90 gear oil.
Transmission Fluid Automatic:
Dexron II or equivalent.
Brake Fluid:
DOT 3 or DOT 4.
Coolant:
Ethylene Glycol based, 50/50 mix with distilled water.
Power Steering Fluid:
ATF Dexron II or equivalent.
Apex Seals:
Wear and failure of apex seals is a common concern with high-mileage rotary engines, leading to compression loss and poor performance. Regular oil changes and proper engine warm-up are crucial.
Oil Consumption:
Rotary engines inherently consume a small amount of oil, which is injected into the combustion chamber to lubricate seals. However, excessive consumption can indicate seal wear.
Turbo System:
Oil leaks, wastegate issues, and turbocharger bearing wear can occur with age and mileage.
Engine Mounts:
Rubber engine mounts can degrade over time, leading to increased vibration.
