Oil Change Interval:
Consult manual (typically 3,000-5,000 miles or 3-6 months for rotary engines, with specific attention to oil level and apex seal lubrication).
Spark Plug Replacement:
Consult manual (rotary engines often use specific spark plug types and require regular replacement for optimal performance).
Air Filter Replacement:
Consult manual (typically every 12,000-15,000 miles).
Coolant Type:
Consult manual (typically a 50/50 mix of ethylene glycol antifreeze and water).
Brake Fluid Type:
Consult manual (likely DOT 3 or DOT 4).
Washer Fluid Capacity:
Consult manual.
Rotary Engine Apex Seals:
Wear or failure of apex seals is a common concern in older rotary engines, leading to compression loss, poor starting, and increased oil consumption. Proper maintenance and avoiding engine abuse are critical.
Carburetor Issues:
Carburetors can be prone to clogging, adjustment issues, and vacuum leaks, requiring regular cleaning and tuning.
Ignition System Maintenance:
Distributor, points, condenser, and ignition coils require periodic inspection and replacement for reliable starting and smooth running.
Cooling System Maintenance:
Radiator, hoses, and water pump need regular checks for leaks and proper function to prevent overheating, especially critical for rotary engines.
Mazda Rotary Pioneering:
Mazda's commitment to the rotary engine, originating with the NSU license, positioned them as a unique manufacturer in the automotive landscape.
