Gear Ratios Manual:
Specific ratios detailed in the manual (e.g., 1st: 3.760, 2nd: 2.261, 3rd: 1.571, 4th: 1.147, 5th: 1.000, 6th: 0.806, Reverse: 3.500)
Transmission Fluid Spec Manual:
API GL-4, SAE 75W-90 (e.g., Mazda Genuine Transmission Oil JWS3309 or equivalent)
Transmission Fluid Spec Automatic:
Dexron III/VI or equivalent
Oil Change Interval:
Recommended every 3,000-5,000 miles or 6 months, whichever comes first. Frequent checks advised due to rotary oil consumption.
Spark Plug Replacement:
Recommended typically every 30,000-60,000 miles, depending on plug type (e.g., multi-electrode vs. single).
Air Filter Replacement:
Recommended every 15,000-30,000 miles or as needed based on driving conditions.
Coolant Flush:
Recommended every 30,000-60,000 miles or 2-4 years.
Engine Oil Type:
Synthetic SAE 5W-30 (e.g., Mazda Genuine Oil or equivalent meeting API SN/ILSAC GF-5 standards). Check manual for specific oil consumption considerations.
Coolant Type:
Mazda Super Long Life Coolant (FL22) or equivalent ethylene glycol-based coolant with deionized water (50/50 mix).
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid.
Apex Seal Wear:
A well-documented concern in rotary engines. Proper warm-up/cool-down procedures and regular oil changes are critical. The manual provides rebuild procedures, but prevention is key.
Carbon Buildup:
Carbon deposits can form in the ports and on the apex seals, affecting compression. 'Italian tune-up' (high RPM driving) and specific cleaning procedures can help.
Ignition System:
Coil packs and spark plug wires can be a failure point; replacement intervals are important.
Oil Consumption:
Rotary engines inherently consume oil to lubricate their seals. Owners must regularly check and top up oil levels.
