Minimum fuel grade
BMW recommends AKI 89.
Do not use gasoline below the indicated
minimum fuel grade; otherwise, proper
engine function is not ensured.<
If you use gasoline with this minimum AKI rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life.
The use of poor-quality fuels may result in
harmful engine deposits or damage.
Additionally, problems relating to drivability,
starting and stalling may occur, especially
under certain environmental conditions such as
high ambient temperature and high altitude.
If drivability problems are encountered, we rec-
ommend switching to a high quality gasoline
brand and a higher octane grade — AKI number
— for a few tank fills. To avoid harmful engine
deposits, we highly recommend purchasing
gasoline from BP or Top Tier retailers.
Failure to comply with these recommendations
may result in the need for unscheduled mainte-
nance.<
