🔧 Maintenance

Engine Oil Change:

Typically every 5,000 km (3,000 miles) or 6 months, but consult the manual for specific recommendations. Rotary engines are known to consume oil as part of their lubrication system.

Coolant Change:

Typically every 2 years or 40,000 km (24,000 miles).

Transmission Fluid Change:

Refer to manual; typically around 40,000-60,000 km (24,000-36,000 miles).

Engine Oil Type:

API SG or higher, viscosity typically 10W-30 or 10W-40. Special attention to oil consumption is critical for rotary engines.

Coolant Type:

Ethylene glycol-based antifreeze coolant (50/50 mix with distilled water).

Brake Fluid Type:

DOT 3 or DOT 4.

Apex Seals:

Wear of apex seals is a common concern in rotary engines, leading to loss of compression. Requires engine rebuild.

Carburetor Issues:

Tuning and maintenance of the Hitachi carburetor can be complex.

Oil Consumption:

Rotary engines naturally consume oil as part of their lubrication design. Ensuring correct oil levels and using appropriate oil is crucial.
