Oil Change Interval:
Every 3,750 miles (6,000 km) or 6 months, whichever comes first (using conventional oil). Synthetic oil can extend this to 7,500 miles (12,000 km) or 12 months.
Engine Oil Filter Replacement:
Replace with every oil change.
Timing Belt Replacement:
Recommended every 60,000 to 90,000 miles (96,000 to 145,000 km) or 7 years for both 4G64 and 6G72 engines, as they are interference engines. Consult the manual for exact interval.
Engine Oil Type:
API Service SG, SH, or SJ rated. Viscosity: SAE 5W-30 or 5W-40 is generally recommended, though 10W-30 can be used in warmer climates. Consult manual for precise recommendation.
Engine Oil Capacity:
Approx. 4.5 quarts (4.3 L) for 4-cyl, Approx. 5.5 quarts (5.2 L) for V6, with filter. Always verify with dipstick.
Coolant Type:
Mitsubishi DiaQueen Super Long Life Coolant (SLLC) or equivalent ethylene glycol-based coolant with deionized water (50/50 mix).
Transmission Fluid Type Automatic:
Mitsubishi DiaQueen ATF SP-II M or equivalent ATF (Dexron III/Mercon compatible, but specific Mitsubishi fluid is preferred).
Transmission Fluid Type Manual:
API GL-4 SAE 75W-90 gear oil. Mitsubishi specifies their own fluid, but equivalents exist.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid.
Common Wear Items:
CV axles, wheel bearings, front suspension bushings, exhaust system components, O2 sensors.
Engine Performance Issues:
Occasional issues with ignition coils, MAF sensor, and fuel injectors leading to misfires or poor performance. Check for vacuum leaks.
Transmission Issues:
Automatic transmissions can sometimes develop issues related to solenoid packs or valve bodies if fluid is not maintained properly. Manual clutches are generally durable but can wear with use.
