Oil Change Interval:
Typically every 5,000 miles (8,000 km) or 6 months, whichever comes first, with full-synthetic oil recommended.
Air Filter Replacement:
Every 15,000 miles (24,000 km) or as needed based on driving conditions.
Spark Plug Replacement:
Refer to specific service schedule, typically around 30,000-60,000 miles, depending on type and use; crucial for rotary health.
Coolant Flush:
Every 30,000 miles (48,000 km) or 2 years.
Engine Oil Type:

Engine Oil Capacity:
Approx. 5.4 US quarts (5.1 liters) with filter change.
Coolant Type:
Mazda FL22 Long Life Coolant (or equivalent P-HOAT coolant).
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid.
Rotary Engine Apex Seals:
Potential for wear or failure if proper maintenance (oil changes, avoiding prolonged idling, proper warm-up/cool-down) is not followed. Symptoms include poor compression, starting issues, and rough running.
Oil Consumption:
Rotary engines naturally consume some oil as part of their lubrication system; regular checks and topping up are essential. The oil metering system plays a crucial role here.
Starter Motor Issues:
Some RX-8 models experienced starter motor failures or slow cranking, especially when hot, which can be exacerbated by low compression or inefficient starting procedures for rotary engines.
Ignition Coil Failure:
Coil packs can degrade over time, leading to misfires and performance issues. The RX-8's double-ignition system means it has multiple coils.
Fuel Pump Failure:
Can lead to starting problems or stalling.
Maintenance Schedule Emphasis
Rotary Specific Maintenance:
The manual will detail critical rotary-specific maintenance, such as ensuring the oil metering system is functioning correctly, proper decarbonization procedures, and the importance of using specific additives or cleaning agents.
