Every 30,000 miles or 2 years.
Fluid Specifications
Engine Oil Type:
Refer to manual for specific API classification and viscosity grade (e.g., 5W-20, 5W-30) and especially for rotary engine oil requirements. Often specific Mazda or rotary-specific oil is recommended.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid.
Power Steering Fluid Type:
Refer to manual for specific Mazda power steering fluid or equivalent.
Known Issues
Apex Seal Wear:
A primary concern for rotary engines; premature wear can lead to loss of compression and engine failure. Regular oil checks and using appropriate oil are critical.
Carbon Buildup:
Carbon deposits can form in the rotor housing and exhaust ports, affecting performance and requiring specific cleaning procedures (e.g., decarbonization).
Starter Motor Issues:
Some models experienced starter motor failures or slow cranking, especially when the engine is hot.
Oil Consumption:
Rotary engines inherently consume oil for lubrication. Monitoring and topping up oil levels between changes is essential.
