Service Intervals General
Oil Change Interval:
Every 3,750 - 7,500 miles (6,000 - 12,000 km) or 6-12 months, depending on driving conditions and oil type (refer to manual for specifics).
Tire Rotation:
Every 7,500 miles (12,000 km).
Engine Air Filter:
Inspect every 15,000 miles (24,000 km), replace as needed or at 30,000 miles (48,000 km).
Cabin Air Filter:
Inspect every 15,000 miles (24,000 km), replace as needed or at 30,000 miles (48,000 km).
Spark Plugs De Gts:
Iridium type, replace every 60,000 - 100,000 miles (96,000 - 160,000 km).
Spark Plugs Gt:
Iridium type, replace every 60,000 - 100,000 miles (96,000 - 160,000 km).
Timing Belt Or Chain:
The 4G69 engine uses a timing belt (replace every 60,000 - 90,000 miles / 96,000 - 144,000 km). The 6G75 V6 engine uses a timing chain, which is generally maintenance-free but requires inspection.

Engine Oil Gt:
SAE 5W-30, API SN or ILSAC GF-5 certified. Capacity: 5.0 qts (4.7 L) with filter.
Transmission Fluid Manual:
API GL-4 or GL-5, SAE 75W-90 gear oil. Capacity varies by transmission type.
Transmission Fluid Automatic:
Mitsubishi DiaQueen ATF J2 or equivalent. Capacity varies by transmission type (approx. 3.5-4.5 qts for drain/refill).
Coolant:
Mitsubishi Super Long Life Coolant (SLLC) or equivalent (Type A). Capacity: approx. 7.5 qts (7.1 L).
Brake Fluid:
DOT 3 or DOT 4 brake fluid.
Engine 4G69:
Oil consumption in some cases, potential timing belt issues if not replaced at recommended intervals.
Engine 6G75:
Can be prone to carbon buildup on intake valves, especially if driven gently. Timing chain is robust but requires proper oil changes.
Transmission Automatic:
Some reports of rough shifting or solenoid issues, particularly on higher mileage vehicles.
Suspension:
Front control arm bushings and sway bar links can wear out, leading to clunks and poor handling.
Electronics:
Occasional issues with power window motors, HVAC blower motors, and ABS sensors.
