Oil Change Interval:
Typically every 3,750 - 7,500 miles (6,000 - 12,000 km) or 6 months, depending on driving conditions and oil type specified in the manual.
Timing Belt Replacement:
Crucial interval, typically 60,000 - 90,000 miles (96,000 - 144,000 km) for DOHC engines, as failure can cause catastrophic engine damage. Manual will specify exact interval.
Transmission Fluid Change:
Recommended every 30,000 - 60,000 miles (48,000 - 96,000 km), depending on transmission type and driving use. Manual will provide precise recommendation and fluid type.
Engine Oil Type Base:
API SG or SH, SAE 10W-30 or 10W-40 recommended. Manual will provide exact specifications.
Engine Oil Type Vr4:
API SG or SH, SAE 5W-30 or 10W-30 recommended for turbo engines. Manual is essential for turbo oil specs.
Coolant Type:
Ethylene glycol based coolant, typically a 50/50 mix with distilled water. Manual will specify capacity and type.
Brake Fluid Type:
DOT 3 or DOT 4 (check manual for exact specification and potential higher performance requirements).
Power Steering Fluid:
Dexron II or equivalent ATF, or specific Mitsubishi fluid. Manual is critical here.
Valve Stem Seals:
Common issue causing blue smoke on startup, especially on higher mileage engines.
Turbo Wear:
Turbocharger seals and bearings can wear over time, leading to loss of boost or oil consumption (VR-4 models).
Ecs Failures:
Electronically Controlled Suspension (ECS) components can fail due to age and electrical issues, leading to stiff ride or leaks.
Active Aero Mechanisms:
Actuators and motors for the active front dam and rear wing can fail, requiring manual diagnosis and repair.
Fuel Pump Reliability:
Some early models may have experienced fuel pump issues; replacement is often a preventative measure.
Mitsubishi Heritage:
Mitsubishi has a long history in motorsport and performance vehicle development, stemming from its early days in automotive manufacturing.
