Engine Name:
Mazda Renesis (13B-MSP)
Engine Type:
Naturally Aspirated Rotary (Wankel)
Displacement:
1.3 L (2 x 654 cc)
Rotor Housing Design:
Side exhaust ports (unique to Renesis) for improved low-end torque and emissions.
Horsepower Standard:
Approximately 210-238 hp (depending on market and transmission, base model usually 210hp)
Torque Standard:
Approximately 159-164 lb-ft
Redline:
Approx. 9,000 RPM
Fuel Delivery:
Sequential Electronic Fuel Injection (SFI)
Fuel Type:
Unleaded Premium Gasoline (91 Octane or higher recommended)
Oil Type:
API SG or SH, ILSAC GF-II or GF-III. Recommended viscosity: 5W-30 or 10W-30. Crucially, rotary engines require specific oil consumption for apex seal lubrication, meaning regular oil level checks are paramount.
Oil Capacity:
Approx. 5.5 US quarts (5.2 liters) with filter change.
Spark Plugs:
Specialized side-gap and intermediate plugs for rotary engines (e.g., NGK R7437-9 for intermediate, NGK RE7CL for side).
Length:
Approx. 174.8 in (4440 mm)
Width:
Approx. 69.7 in (1770 mm)
Height:
Approx. 52.8 in (1340 mm)
Wheelbase:
Approx. 106.4 in (2700 mm)
Front Track:
Approx. 60.2 in (1530 mm)
Rear Track:
Approx. 60.6 in (1540 mm)
Curb Weight Manual:
Approx. 3,000-3,100 lbs (1360-1406 kg)
Curb Weight Automatic:
Approx. 3,150-3,250 lbs (1430-1475 kg)
Cargo Volume:
Approx. 8.7 cu ft (246 liters) in the trunk
Oil Change Interval:
Typically every 5,000 miles (8,000 km) or 6 months, whichever comes first. Crucially, owners must frequently check oil level between changes due to inherent rotary oil consumption for seal lubrication.
Air Filter Replacement:
Every 15,000-20,000 miles (24,000-32,000 km) or as needed based on driving conditions.
Spark Plug Replacement:
Specialized spark plugs require periodic replacement. Consult the manual for specific intervals, often around 30,000-60,000 miles, depending on plug type and usage.
Coolant Flush:
Every 30,000 miles (48,000 km) or 2 years.
Transmission Fluid Change:
Manual: 60,000 miles (96,000 km). Automatic: 45,000-60,000 miles (72,000-96,000 km) or as specified by Mazda.
Differential Fluid Change:
Every 45,000-60,000 miles (72,000-96,000 km).
Brake Fluid:
DOT 3 or DOT 4.
Power Steering Fluid:
Mazda Genuine Power Steering Fluid or ATF Dexron III equivalent.
Apex Seal Wear:
The primary concern with the Renesis is potential apex seal wear if the engine is not properly maintained, especially regarding oil levels, correct oil type, and avoiding prolonged low-RPM operation (engine 'flooding').
Ignition System:
Coil-on-plug system can be prone to failure; using correct spark plugs and maintaining ignition coils is crucial.
Carbon Buildup:
Carbon buildup in the rotor housings and exhaust ports can occur, especially with short-distance driving. Regular high-RPM driving helps to clear this.
Oil Injection System:
The two-stroke oil injection system is vital for lubrication and requires using the correct pre-mix oil or ensuring the reservoir is topped up with appropriate 2-stroke oil.
