3. Step-by-Step Oil Change Procedure
Follow these detailed steps to properly change the oil in your Mitsubishi Galant. Total time: 45-60 minutes for beginners.
Preparation & Safety
Park on level ground, engage parking brake, and gather supplies: correct oil amount, new filter, drain pan, funnel, 14mm wrench, filter wrench, gloves, and rags.
Warm Up Engine
Run engine for 5-10 minutes to warm oil (not hot). Warm oil flows better and carries more contaminants with it.
Drain Old Oil
Locate drain plug under engine (14mm bolt). Place drain pan underneath, remove plug carefully (hot oil!), allow complete drainage (10-15 minutes).
Replace Oil Filter
Remove old filter (counter-clockwise). Clean filter mating surface. Apply thin coat of new oil to filter gasket. Install new filter hand-tight plus ¾ turn.
Refill with New Oil
Replace drain plug with new washer (torque: 22-25 ft-lbs). Add 0.5 quarts less than full capacity through funnel. Wait 2 minutes, check dipstick, add in 0.25 quart increments until “Full”.
Final Checks
Start engine, let run 1 minute, check for leaks. Turn off, wait 2 minutes, check dipstick again. Record mileage and reset maintenance light if equipped.
4. Frequently Asked Questions (FAQ)
Answers to the most common questions about Mitsubishi Galant oil changes and maintenance.
Overfilling can cause serious damage: Excess oil can foam when churned by the crankshaft, leading to:
- Reduced lubrication effectiveness
- Increased oil pressure
- Oil entering PCV system and being burned
- Potential seal damage and oil leaks
Solution: If overfilled, drain excess immediately using the drain plug or oil extraction pump.
Yes, absolutely. Synthetic oil is compatible with all Galant engines and provides superior protection. Benefits include:
- Better high-temperature stability
- Improved cold-start protection
- Extended change intervals
- Reduced engine wear
Note: No special flush needed. Just drain conventional and fill with synthetic.
Some oil consumption is normal (up to 1 quart per 1,000 miles for high-mileage engines). Common causes in Galants:
- PCV valve failure: $15 part, easy replacement
- Valve stem seals: Common on 200K+ mile engines
- Piston rings: More significant repair needed
- External leaks: Valve cover gasket, oil pan seal
Monitor consumption rate. If exceeding 1qt/1,000mi, have engine inspected.
2006 Mitsubishi Galant 2.4L (4G69 engine):
- With filter change: 4.6 US quarts (4.35 liters)
- Without filter: 4.1 US quarts (3.88 liters)
- Recommended oil: API SP/SN 5W-30
- Filter: MZ690116 or equivalent
This applies to all 2004-2012 2.4L models. The 2006 model year saw no changes to oil capacity specifications.
For 2004-2012 Galants:
- Turn ignition to “ON” (don’t start engine)
- Press the “TRIP” button until “OIL” appears on display
- Press and hold “TRIP” for 10+ seconds until it beeps/resets
- Turn ignition off, then start to verify reset
For 1999-2003: Use the maintenance reset button under dashboard (left of steering column).
For 1994-1998: No electronic reset – manual record keeping only.
