BMW recommends 91 AKI and permits 87 AKI as the minimum grade, with possible drivability effects at the minimum. E10 is supported. The 21.9-US-gallon tank converts to 82.9 L.

What happens if I use a lower octane fuel?

The minimum is permitted by the source while the higher grade is recommended. We do not assume a performance or economy benefit beyond the source.
