Complete Oil Specifications
BMW’s owner’s manual for the 2023 X7 lists these oil specifications for the gasoline engine: BMW Longlife-01 FE, BMW Longlife-17 FE+ and BMW Longlife-22 FE++, in SAE 0W-12, 0W-20 or 0W-30.
The manual rules some of these out for other engines: Longlife-17 FE+ and 0W-20 aren’t suitable for the 50i engine, and Longlife-22 FE++ and 0W-12 aren’t suitable for the 60i engine. Neither exclusion applies to the xDrive40i.
Which Viscosity?
BMW says the suitable viscosity grade for your vehicle is shown on a sign in the engine compartment. Use that sign to choose between 0W-12, 0W-20 and 0W-30.
Topping Up Without Longlife Oil
If an oil suitable for continuous use isn’t available, BMW allows adding up to 1 US quart (1 liter) of API SL, API SM or API SN oil, as a top-up only. The manual also warns against oil additives.
What We Couldn’t Confirm
- Engine oil capacity. BMW’s owner’s manual doesn’t publish a fixed figure.
- Displacement and engine code. The manual identifies the model as the X7 xDrive40i and doesn’t print the B58 code.
- OEM oil filter part number and drain plug torque. Neither appears in the owner’s manual.
