🔧 Maintenance

Oil Change:

Every 3,000-5,000 miles or 6 months, whichever comes first. Refer to manual for specific oil type and capacity.

Air Filter Replacement:

Inspect every 15,000 miles, replace as needed or at 30,000 miles.

Spark Plug Replacement:

Refer to manual for specific rotary spark plug recommendations and intervals (often requires specific multi-ground plugs).

Engine Oil:

API SG or higher, SAE 10W-30 or 10W-40 recommended. Check manual for specific rotary oil requirements (some may recommend specific additives or oil types).

Coolant:

Ethylene glycol-based antifreeze, 50/50 mixture with distilled water.

Apex Seal Wear:

Premature wear of apex seals can lead to compression loss and engine failure. Regular maintenance and proper warm-up/cool-down are crucial.

Oil Consumption:

Rotary engines naturally consume some oil as part of their lubrication system. Monitor oil level frequently.

Carburetor Issues:

Older carbureted systems can be prone to wear and require careful tuning and cleaning. Manual provides detailed carburetor adjustment procedures.

Chassis Rust:

As with many vehicles of this era, rust can be a significant issue, particularly in coastal or high-humidity environments. Manual may cover some body repair but not extensive rust treatment.
