The 2015 BMW X3’s oil capacity depends on the engine: roughly 6.0 quarts (5.7 liters) with the filter for the 2.0-liter turbo, and about 7.0 quarts (6.6 liters) with the filter for the 3.0-liter turbo.
In this article, we outline the capacity by engine variant, explain how to confirm the correct amount for your vehicle, and share practical notes for performing an accurate oil change.
Engine-specific oil capacities
2.0L turbo inline-4 (xDrive28i)
Capacity details for the most common X3 28i configuration:
- Oil capacity with filter: 6.0 quarts (5.7 liters).
- Recommended oil grade: synthetic 5W-30 or 0W-40, depending on climate and model year; confirm the exact specification in the owner's manual or service portal.
These figures reflect a standard oil change including the engine oil filter. VIN-specific variations can occur, so verify against your vehicle’s documentation.
3.0L turbo inline-6 (xDrive35i)
Capacity details for the larger engine variant:
- Oil capacity with filter: 7.0 quarts (6.6 liters).
- Recommended oil grade: typically synthetic 5W-30 or 0W-40, climate-dependent; verify the exact spec for your vehicle's VIN.
As with the 2.0L model, these values assume a standard change with the filter included and may vary slightly by production batch or regional specification.
Market variations and maintenance notes
In markets outside the U.S. or on other X3 trims, there may be diesel or additional gasoline variants with different capacities. Always consult the vehicle’s manual, the BMW Service Information Portal, or a dealer to confirm the precise oil capacity for your VIN.
In short, plan for about 6.0 quarts (5.7 liters) of oil for the 2.0L turbo and about 7.0 quarts (6.6 liters) for the 3.0L turbo, with the oil filter included in the total. Always verify the exact specification for your VIN and market in the owner's manual or through official BMW resources.
