Engine Oil Change Interval:
Every 5,000 to 7,500 miles (8,000 to 12,000 km) or 6 months, whichever comes first, using synthetic or high-quality conventional oil.
Timing Belt Replacement Interval:
Crucial: typically 60,000 to 90,000 miles (96,000 to 144,000 km) or 7 years. Failure can cause catastrophic engine damage.
Coolant Flush Interval:
Every 2 years or 30,000 miles (48,000 km).
Engine Oil Specification:
API SJ or SL service category. Viscosity: 5W-30 or 10W-30 recommended, depending on climate. Refer to manual for precise specification.
Coolant Specification:
Ethylene glycol-based antifreeze, typically a 50/50 mix with distilled water. Mazda coolant or equivalent (e.g., Peak Long Life) is recommended.
Brake Fluid Specification:
DOT 3 or DOT 4 brake fluid.
Power Steering Fluid:
Refer to manual; typically ATF Dexron-II or III, or a specific Mazda power steering fluid.
Manual Transmission Fluid:
API GL-4 gear oil, viscosity typically 75W-90 or 80W-90. Refer to manual for exact specification.
Common Issues Engine:
Timing belt wear (leading to breakage), oil leaks from valve cover gasket or oil pan gasket, potential for intake manifold gasket leaks.
Common Issues Suspension:

Common Issues Electrical:
Degradation of wiring harness insulation over time, faulty power window motors, instrument cluster gauge issues.
Common Issues Brakes:
Worn brake pads and rotors are standard wear items. Parking brake adjustment may be needed over time.
