Oil Change:
Every 5,000 km or 3 months (whichever comes first), recommended. Original interval may differ.
Spark Plug Replacement:
Inspect at 10,000 km, replace as needed. Consult manual for specific interval.
Air Filter Replacement:
Inspect at 10,000 km, replace every 20,000 km or as needed.
Rotor Apex Seal Inspection:
Periodic inspection recommended as part of engine health checks, though not a fixed interval replacement item.
Brake Fluid:
DOT 3 or DOT 4 (consult manual for specific type)
Coolant:
50/50 mix of Ethylene Glycol and Distilled Water
Apex Seals:
Wear of apex seals over time, leading to compression loss and performance degradation. Requires engine rebuild.
Oil Consumption:
Rotary engines inherently consume some oil as part of their lubrication system; excessive consumption indicates seal wear or other issues.
Carburetor Tuning:
Carburetors can become finicky with age and require regular adjustment for optimal performance and emissions.
Chassis Rust:
Common for vehicles of this era, especially in areas with road salt. Structural integrity can be compromised.
