Why Engine Maintenance Matters More Than Ever
More recent Mitsubishi engines will last in excess of 200,000 miles under good maintenance. But without maintenance, even the longest-lasting engine will begin to accumulate defects leading to costly repairs or outright replacement.
Top 5 Reasons to Service Your Mitsubishi Engine:
- Maximize engine life and performance
- Prevent costly breakdowns and overheating
- Maintain fuel efficiency and emissions compliance
- Avoid premature wear on gaskets, pistons, and timing components
- Keep resale value and reliability intact
Regular Maintenance Schedule for Mitsubishi Engines
This is a typical maintenance schedule recommended for Mitsubishi gasoline engines. Make sure to consult your vehicle service manual for model-specific intervals.
| Task | Recommended Interval |
|---|---|
| Engine oil & filter | Every 3,000–5,000 miles |
| Air filter replacement | Every 15,000–30,000 miles |
| Spark plugs | Every 30,000–60,000 miles |
| Timing belt/chain | 60,000–100,000 miles (varies) |
| Fuel system cleaning | Every 30,000 miles |
| Coolant flush | Every 50,000 miles or 5 years |
| Transmission fluid | Every 60,000 miles |
| Valve adjustment (if needed) | Every 60,000–90,000 miles |
Key Tips to Keep Your Mitsubishi Engine Running Strong
1. Use High-Quality Engine Oil
Mitsubishi engines lubricate internal components with oil, regulate temperature, and prevent accumulation. Use only grades of oil designated by the manufacturer — typically 5W-30 or 0W-20 full synthetic.
✅ Tip: Choose oils that are API SN or better and ILSAC GF-6 rated.
2. Monitor Engine Temperatures
Overheating is among the most common causes of engine failure. Have the cooling system (radiator, hoses, thermostat) inspected regularly and coolant topped off with the correct type (usually long-life ethylene glycol-based coolant).
✅ Warning Signs: Temperature gauge spikes, sweet odor from vents, or steam from the hood.
3. Replace Timing Belts & Chains on Time
Many Mitsubishi engines — especially the older ones like the 4G63 or 6G72 — require timing belts that should be replaced at 60,000–100,000 miles. A failure can lead to catastrophic engine ruin.
✅ Pro Tip: Replace the tensioners and the water pump while servicing the belt.
4. Clean or Replace Air Filters
A dirty air filter starves your engine and reduces combustion efficiency. Replace it every 15,000–30,000 miles, or more often in dusty conditions.
5. Keep Fuel System Clean
Carbon deposits in fuel injectors or valves can reduce engine power and fuel economy. Use quality fuel and occasional injector cleaner to ensure proper combustion.
6. Check for Early Signs of Engine Trouble
- Check engine light
- Wasteful fuel usage
- Misfire or rough idle
- Tapping or clattering noises
- Oil consumption or leaks
A timely catch can lead to a quick repair — or a complete engine replacement.
