The 2014 BMW 428i uses synthetic engine oil that meets BMW Longlife-04 specifications, with 5W-30 as the standard viscosity. In very cold climates, 0W-30 LL-04 is also acceptable. Always verify the exact requirement in the owner's manual or with a BMW service advisor.
Oil specifications for the 428i
The 428i relies on a 2.0-liter turbocharged inline-four engine. BMW requires engine oil that conforms to the Longlife-04 standard to support extended service intervals and emissions-control systems.
Suitable viscosities
For most climates, BMW recommends synthetic oil meeting LL-04 with a viscosity of 5W-30. In very cold environments, 0W-30 LL-04 is also acceptable. Some markets may permit other LL-04 oils (such as 0W-40 or 5W-40) depending on conditions, but 5W-30 LL-04 is the typical default.
Recommended oil options
Below are the common options that satisfy LL-04 for the 428i. Ensure the bottle states "BMW Longlife-04" and choose the viscosity appropriate for your climate.
- Synthetic engine oil with BMW Longlife-04 (LL-04) approval.
- Viscosity: 5W-30 (standard for most climates).
- Viscosity: 0W-30 (acceptable in very cold climates).
In short, always choose LL-04 oil with the correct viscosity for your climate to maintain performance and warranty standards.
Oil capacity and maintenance interval
The N20 engine used in the 428i holds about 6.0 quarts (5.7 liters) of oil with a full oil change. BMW's Longlife-04 service intervals can extend up to roughly 15,000 miles (24,000 km) under normal driving, but many owners service closer to 10,000–12,000 miles depending on driving conditions and local recommendations. Always follow the schedule for your vehicle’s VIN.
How to verify you're using the right oil
Before you buy or top off oil, verify the specification and viscosity on the label.
- Check the bottle for "BMW Longlife-04" (LL-04) approval.
- Confirm the viscosity is 5W-30 or 0W-30, depending on your climate.
- Use a reputable brand or a BMW-approved oil to avoid warranty issues.
Choosing LL-04 approved oil with the correct viscosity is essential for engine protection and to preserve warranty coverage. If you’re unsure, contact a BMW dealer or service center for the right oil specification for your vehicle.
