🔧 Maintenance

Engine Oil Change:

Every 3,750 miles (6,000 km) or 6 months, whichever comes first (severe duty).

Engine Oil Filter:

Replace with every oil change.

Spark Plugs:

Inspect every 30,000 miles (48,000 km), replace as needed. (Iridium spark plugs recommended).

Transmission Fluid:

Every 30,000 miles (48,000 km) or 24 months.

Differential Fluid Front Rear:

Every 30,000 miles (48,000 km) or 24 months (includes ACD/AYC fluid if applicable).

Engine Oil:

API SG or higher, ACEA A3/B3, SAE 5W-30 synthetic recommended (check manual for specific Mitsubishi part numbers and viscosity ranges).

Coolant:

Mitsubishi Super Long Life Coolant (MS-97641) or equivalent ethylene glycol-based coolant with a 50/50 mix of distilled water.

Brake Fluid:

DOT 3 or DOT 4 (check manual for specific recommendation).

Engine Oil Consumption:

Some 4G63 engines can consume oil, especially when driven hard. Regular checks are essential. Piston ring wear can be a cause.

Acd Ayc Pump:

The ACD/AYC hydraulic pump can fail, leading to system errors. Ensure proper fluid levels and pump operation.

Clutch Wear:

High-performance clutch can wear faster with aggressive driving. Manual transmission clutch can require replacement over time.

Turbocharger Wear:

While robust, aggressive use without proper warm-up/cool-down cycles can lead to premature turbo wear.

Timing Belt Serpentine Belt:

Serpentine belt requires inspection and replacement per schedule. Timing belt is not applicable as the 4G63 uses a timing chain.
