| Standard | BMW Longlife-17 FE+, ACEA C5 |
| Capacity (with filter) | 5.6 quarts |
| Capacity (without filter) | 5.3 quarts |
| Oil Filter | BMW 11428575211 |
| Interval | CBS (Condition Based Service) — Max 10,000 miles/1 year |
Why BMW Longlife-17 FE+ is Required
The B48 TwinPower Turbo in the X4 combines a twin-scroll turbocharger, Valvetronic variable valve lift, Double-VANOS variable cam timing, and Spray-Guided Direct Injection into a single architecture. BMW developed the LL-17 FE+ specification specifically to handle the thermal stress of this system: ACEA C5 oils use low-SAPS chemistry (reduced sulphated ash, phosphorus, and sulphur) to protect the three-way catalyst and prevent ash deposits on piston rings, while the 0W-20 viscosity minimizes cold-start friction on the Valvetronic actuator linkage.
Using incorrect oil will:
- ❌ Deposit ash on piston rings and degrade catalytic converter efficiency if high-SAPS oil is used
- ❌ Fail to lubricate Valvetronic eccentric shaft components correctly at cold start
- ❌ Trigger CBS to shorten service intervals if oil quality sensor detects wrong chemistry
BMW-Approved Oil Brands
-
✅ BMW TwinPower Turbo Oil 0W-20 LL-17 FE+
-
✅ Castrol EDGE Professional LL FE 0W-20
-
✅ Mobil 1 ESP X2 0W-20
-
✅ Shell Helix Ultra ECT C5 0W-20
-
✅ Total Quartz INEO MDC 0W-20
The oil container must explicitly state BMW Longlife-17 FE+ approval. Standard API SP oils — even 0W-20 — do not meet this specification. BMW’s ACEA C5 requirement is distinct from the more common ACEA C3 used in many European cars.
Severe Service Check
Use the 5000-mile interval if you:
- Frequently use Sport or Sport+ driving modes
- Drive primarily short urban trips where the engine does not fully warm up
- Operate in sustained high-load conditions (mountain driving, frequent highway merging)
- Experience ambient temperatures consistently below 14°F
Installation Details
Drain Plug Torque: 18 Nm (13.3 ft-lbs)
BMW uses a plastic expansion drain plug on the B48 — do not overtighten. Replace the drain plug at every oil change (part: BMW 07 11 9 904 001).
OEM Filter: BMW 11428575211
Aftermarket Filters:
-
Mann-Filter HU716/2x
-
Mahle OX 1049/2D
-
Bosch 0451103298
Pro Tip: Loosen the oil filter cap (27mm socket, torque to 25 Nm on reinstall) before removing the drain plug — this allows oil to drain back from the filter housing into the sump first, reducing mess. The filter element is cartridge-style, located in the top of the engine on the driver side. BMW’s CBS will display the exact remaining oil service life in miles and days on the iDrive screen.
FAQs
What oil does a 2023 BMW X4 xDrive30i take?
0W-20 full synthetic meeting BMW Longlife-17 FE+ and ACEA C5. Do not substitute generic 0W-20 that lacks the LL-17 FE+ certification.
How many quarts does the BMW X4 B48 need?
5.6 quarts with a new filter, 5.3 without.
Can I use BMW LL-04 oil (5W-30) instead?
LL-04 is an older spec; the 2023 X4 B48 requires the newer LL-17 FE+ (0W-20). Using LL-04 oil is not recommended for this engine generation.
How does BMW’s Condition Based Service work?
The CBS system monitors driving patterns, oil temperature, and engine load to calculate actual oil degradation. It may allow up to 10,000 miles between changes under ideal conditions, or prompt earlier changes in city driving or extreme temperatures.
Is synthetic oil required?
Yes. Only full synthetic oil carrying the BMW Longlife-17 FE+ approval meets the X4’s specifications.
