🔧 Maintenance

Oil Change Interval:

Typically every 3,750 miles (6,000 km) or 6 months, whichever comes first. Consult manual for precise recommendations.

Spark Plug Replacement:

Refer to manual. Rotary apex seals and spark plug life can vary. Early indication of issues via poor starting/idle.

Timing Belt Equivalent:

Rotary engines do not have timing belts; they use internal chain/sprockets for rotor gear drive. No specific interval, but requires specialized inspection.

Transmission Fluid Change:

Typically every 30,000 miles (48,000 km) or 24 months.

Engine Oil Type:

API SG, SF, or SE rated, SAE 10W-30 recommended. Crucial to use quality oil for rotary longevity. Premixing 2-stroke oil is NOT a factory spec for the FD, rely on the automatic oil injection system.

Coolant Type:

Ethylene Glycol based antifreeze, mixed 50/50 with distilled water. Mazda FL22 coolant may be suitable as a long-life option.

Brake Fluid Type:

DOT 3 or DOT 4.

Power Steering Fluid:

Dexron II or equivalent automatic transmission fluid (ATF).

Rotary Specific:

Apex seal wear, eccentric shaft wear, oil seal issues, potential for overheating if cooling system is not maintained. Premature failure if oil injection system fails or inadequate lubrication is provided.

Turbocharger System:

Sequential turbo system complexity can lead to vacuum hose issues, boost leaks, and turbo failure if not serviced.

Electrical:

Corrosion in connectors, aging wiring harnesses, ECU capacitor issues (common on later FD models, less so on early ones, but still possible).

Fuel System:

Fuel injector clogging, fuel pump degradation.

Cooling System:

Radiator leaks, hose degradation, water pump failure.
