🔧 Maintenance

Oil Change Interval:

Every 3,000-5,000 miles (5,000-8,000 km) or 6 months, depending on driving conditions. Rotary engines require frequent oil changes.

Spark Plug Replacement:

Refer to manual; typically around 30,000 miles (48,000 km) for specific rotary spark plugs.

Belt Replacement:

Serpentine belt and any ancillary belts should be inspected regularly and replaced if cracked or worn, typically every 60,000 miles (96,000 km).

Engine Oil Type:

API SG or SH, SAE 10W-30 or 10W-40 Synthetic Recommended. Specific rotary oil additives might be beneficial.

Coolant Type:

Mazda FL22 Long Life Coolant or equivalent (50/50 mix with distilled water)

Transmission Fluid Manual:

API GL-4 75W-90 Gear Oil

Transmission Fluid Automatic:

Dexron III or equivalent

Differential Fluid:

API GL-5 75W-90 Gear Oil

Brake Fluid:

DOT 3 or DOT 4

Apex Seals:

Wear and failure of apex seals due to improper maintenance, overheating, or detonation is a common concern.

Pre Mix Oil System:

The automatic oil injection system (pre-mix) can clog or fail, requiring manual addition of 2-stroke oil to the fuel tank.

Vacuum Lines:

Aging and brittle vacuum lines can lead to boost leaks and drivability issues.

Catalytic Converter:

Overheating or clogging of the catalytic converter can occur, impacting performance.

Cooling System:

The rotary engine runs hot; a properly functioning cooling system, including the air-to-air intercooler and radiator, is critical.
