Always verify the final level with the dipstick, as variations in filters or slight manufacturing tolerances can affect the exact amount needed.
Official capacity and practical guidance
To help you understand how much oil to pour and how to measure it, here is the official capacity and a quick guide to the filling process.
- Capacity with filter installed: 5 quarts (4.7 liters).
Conclusion: Start with 5 quarts, then check the level on the dipstick. Add small amounts as needed to bring the level to the full mark after the oil has settled, and avoid overfilling.
Practical oil-change steps
Before starting an oil change, prepare the right oil grade, a new filter, and the necessary tools. The typical process yields the 5-quart capacity reference.
- Drain the old oil completely by removing the drain plug and allowing it to flow into a suitable container.
- Replace the oil filter with a new one designed for the 2.5L engine.
- Pour in 5 quarts of oil, then start the engine and run it for a brief moment to bring oil pressure up.
- Turn off the engine and recheck the level with the dipstick; add more oil as needed to reach the full mark.
Conclusion: A careful oil-change procedure ensures the engine is properly lubricated and avoids overfill or leaks. The 5-quart capacity is the baseline for a typical change with a new filter.

Oil type and climate considerations
Use an API-certified oil compatible with older engines. For many climates and driving conditions on the 2.5L Jeep, 5W-30 or 10W-30 conventional oil is common, though synthetic or high-mileage formulations may be preferred in extreme temperatures or with higher mileage. Always follow the vehicle’s manual or a trusted mechanic for the exact recommendations for your specific vehicle.
