Torque Range:
Approx. 115-125 lb-ft (depending on market and specific model/carburetion)
Fuel Delivery:
Carburetor (e.g., Hitachi, Nikki) or early fuel injection systems (less common)
Fuel Type:
Unleaded gasoline (may require specific octane ratings as per manual)
Safety Features Era:
Basic safety features for the era; dual-circuit hydraulic brakes, seat belts, padded dashboard, collapsible steering column.
Braking System:
Front disc brakes (standard on most RX-2/RX-3, though early models/trims might have had all-drum), rear drum brakes. Dual-circuit hydraulic system.
Restraint Systems:
Lap and shoulder belts (front), lap belts (rear). Body-structure integrity typical for the era.
Oil Change Interval:
Typically every 3,000-5,000 miles or 3-6 months. Specific interval to be confirmed in manual.
Spark Plug Service:
Requires specific pre-mixed oil for lubrication of apex seals; interval for apex seal inspection/replacement is critical and detailed in the manual.
Engine Oil Type:
Specific rotary engine oil or a high-quality mineral/synthetic oil meeting Mazda's specifications for the 12A engine. Crucially, requires oil injection into the fuel or intake tract for apex seal lubrication. Manual will specify viscosity and type.
Transmission Fluid Type:
Manual transmission fluid (MTF) or gear oil, viscosity to be specified in the manual (e.g., GL-4).
Coolant Type:
Ethylene glycol-based coolant, typically a 50/50 mix with distilled water. Specifics in manual.
Rotary Apex Seals:
Wear or failure of apex seals is a common issue in high-mileage rotary engines, leading to compression loss. Manual provides diagnosis and rebuild procedures.
Carburetor Issues:
Carburetor wear, clogging, or tuning issues can affect performance and fuel economy. Manual details carburetor overhaul and adjustment.
Oil Injection System:
Blockage or failure of the oil injection system can lead to rapid apex seal wear. Manual covers diagnosis and repair of this critical system.
