Oil Change:
Every 3,000-5,000 miles (5,000-8,000 km) or 6 months, depending on driving conditions.
Spark Plugs:
Inspect/replace at 30,000 miles (50,000 km). Requires specific rotary spark plugs (e.g., NGK BPR7EIX).
Air Filter:
Inspect every 15,000 miles (24,000 km), replace as needed.
Engine Oil:
API SG or higher, SAE 10W-30 or 10W-40 recommended. Rotary engines require specific oil additive packages. Check manual for exact specs.
Coolant:
Ethylene glycol-based coolant, 50/50 mix with distilled water.
Transmission Fluid:
API GL-4, SAE 75W-90 or 80W-90 gear oil.
Brake Fluid:

Apex Seals:
Wear and failure of apex seals leading to compression loss and engine failure. Crucial to monitor compression.
Oil Consumption:
Rotary engines consume oil by design for lubrication. Premixing or proper oil metering is vital. Excessive consumption indicates issues.
Overheating:
Can be prone to overheating if cooling system is not maintained. Check radiator, hoses, and water pump.
Vacuum Leaks:
Aging rubber hoses and gaskets can lead to vacuum leaks, affecting engine performance and idle.
