About five quarts (roughly 4.7 liters) of engine oil, including the filter, are typically required for a full oil change on the 2015 Malibu 2.5.
That capacity applies to a standard drain-and-fill. If you’re using a different filter or performing only a top-up, the amount may vary slightly. Always verify the level with the dipstick after adding oil and consult the owner's manual for exact specifications.
Capacity and oil specifications
The 2.5-liter EcoTec engine in the 2015 Malibu generally requires five quarts of oil when you include the new filter. The recommended oil is 5W-30 that meets Dexos1 specification (API SN or later). Owners may choose synthetic or synthetic-blend oil for protection and longer change intervals, but always confirm with the owner's manual or GM service data for your exact vehicle.
What you’ll need for a standard oil change:
- Oil quantity: 5 quarts (4.7 L) including the filter
- Oil type: 5W-30 Dexos1-certified (synthetic or synthetic blend recommended)
- Oil filter compatible with the 2.5L engine
- Oil filter wrench and funnel
- Rags and a drain pan for catching old oil
Note: Some variations can occur due to filter design or climate, but the dipstick should show full when the process is complete.
Steps to fill and verify the oil level
To avoid overfilling or underfilling, follow a careful sequence when adding oil and checking the level.
- Park on level ground and turn off the engine. Wait 5-10 minutes for oil to settle.
- Open the hood, locate the dipstick, and wipe it clean.
- Remove the oil filler cap, and add oil in small increments (about 0.5-1 quart at a time).
- Recheck the dipstick after each increment until the level approaches the "Full" mark.
- Run the engine for 1-2 minutes, then turn it off and wait a few minutes. Recheck the level and top off if needed.
Finish by reinstalling the cap, cleaning up spills, and disposing of old oil and the filter responsibly.
Alternative considerations
Some owners may vary slightly in the amount if using a different brand of filter or oil, but starting with five quarts and adjusting based on the dipstick reading is a reliable approach. If in doubt, consult a dealership or a trusted mechanic.
Summary
The 2015 Malibu with a 2.5L engine typically requires about five quarts of engine oil, including the filter, for a full change. Use a 5W-30 Dexos1-certified oil, verify levels with the dipstick, and follow the recommended procedure to ensure proper lubrication and engine protection.
