Oil Change:
Every 3,000 - 5,000 miles or 6 months, or as per manual, using appropriate synthetic oil.
Spark Plugs:
Rotary specific plugs, check intervals in manual (typically around 30,000 miles but depends on type).
Timing Belt Chain:
Rotary engines do not have timing belts; they have a timing chain/gear system which is more durable but requires inspection.
Engine Oil:
API SG or higher, viscosity typically 10W-30 or 5W-30 synthetic. Check manual for precise spec.
Coolant:
Mazda long-life coolant or equivalent (50/50 mix with distilled water).
Transmission Fluid:
GL-4 gear oil (e.g., 75W-90) for manual transmission. ATF Type T-IV or equivalent for automatic. Check manual.
Apex Seals:
Wear or failure of apex seals is a common concern with high mileage rotary engines, leading to compression loss.
Sequential Turbo System:
Failures in the solenoids or actuators controlling the twin-turbo sequence can impact power delivery.
Oil Consumption:
Rotary engines naturally consume oil as part of their lubrication system; consistent checking and topping up is crucial.
Catalytic Converter:
Can be susceptible to failure if the engine is not maintained properly, leading to performance issues.
Mazda Sports Legacy:
Mazda has a long history with rotary engines, notably with the Cosmo and the legendary RX-7 and RX-8 models.
Previous Generations:
SA22C (1978-1985), FC3S (1986-1991)
Fd Design Goals:
To be a true supercar, surpassing performance benchmarks of its time with advanced engineering.
