Oil Change Interval:
Typically every 5,000 - 7,500 miles (8,000 - 12,000 km) or 6-12 months, whichever comes first, depending on driving conditions and oil type.
Timing Belt Replacement:
Critical interval for 4G63 and 6A13 engines, typically around 60,000 - 90,000 miles (100,000 - 145,000 km). Consult the manual for exact specifications.
Spark Plug Replacement:

Engine Oil Type:
API SG/SH or ILSAC GF-2 rated synthetic or semi-synthetic oil. Viscosity typically 5W-30 or 10W-30 depending on climate. Refer to manual for exact recommendations.
Coolant Type:
Ethylene glycol-based coolant. Typically a 50/50 mix of antifreeze and distilled water. Use genuine Mitsubishi coolant or equivalent.
Transmission Fluid Manual:
API GL-4 or GL-5 gear oil, viscosity dependent on temperature. Specific grade for 5-speed and 6-speed transmissions may differ.
Transmission Fluid Automatic:

Engine Common Issues:
Timing belt failure (if not replaced on schedule), oil leaks from seals and gaskets, carbon build-up on intake valves (especially on GDI engines if applicable to later models/variants, though less common on this specific era).
Transmission Common Issues:
Wear in manual transmission synchros, potential for automatic transmission solenoid issues or torque converter problems if fluid maintenance is neglected.
Suspension Common Issues:
Worn ball joints, bushings, and control arms due to age and mileage. Rattle from strut mounts.
Electrical Common Issues:
Corrosion in wiring harnesses, failure of power window motors, intermittent issues with door lock actuators, sensor failures (e.g., crank/cam sensors).
Rust Prone Areas:
Wheel arches, rocker panels, and rear quarter panels can be susceptible to rust depending on climate and maintenance history.
