Fuel Type:
Unleaded Gasoline
Oil Change Interval:
Every 5,000 miles or 6 months, whichever comes first.
Timing Belt Replacement:
Every 60,000 to 90,000 miles or 5-7 years, depending on engine and driving conditions. CRITICAL to follow this for interference engines.
Spark Plug Replacement:
Every 30,000 to 60,000 miles (depending on plug type and engine).
Engine Oil:
API SG or SH, SAE 5W-30 or 10W-30 (check owner's manual for specific temperature ranges).
Coolant:
Mazda FL22 Long Life Coolant or equivalent silicate-free, ethylene glycol-based coolant (typically green).

Manual Transmission Fluid:
API GL-4 SAE 75W-90 gear oil.
Power Steering Fluid:
Mazda Genuine Power Steering Fluid or Dexron II/III ATF.
Engine Sludge:
Certain engines, particularly early BP engines, can be prone to oil sludge buildup if maintenance is neglected. Regular oil changes are crucial.
Cv Joint Wear:
Front CV joints can wear out, leading to clicking noises during turns.
Rust:
As with many cars of this era, rust can be a concern, particularly in areas with road salt. Check wheel wells, rocker panels, and subframes.
Oxygen Sensor Failure:
O2 sensors can fail over time, impacting fuel economy and emissions.
Catalytic Converter Clogging:
Can occur due to engine issues or age, leading to poor performance.
