CAUTION
The use of poor-quality fuels may result in
harmful engine deposits or damage. Addi-
tionally, problems relating to drivability,
starting and stalling, especially under cer-
tain environmental conditions such as
high ambient temperature and high alti-
tude, may occur.
If drivability problems are encountered,
we recommend switching to a high quality
gasoline brand and a higher octane grade
— AKI number — for a few tank fills. To
avoid harmful engine deposits, it is highly
recommended to purchase gasoline from
Top Tier retailers.
Failure to comply with these recommenda-
tions may result in the need for unsched-
uled maintenance.
Recommended fuel grade
MINI recommends AKI 91.
John Cooper Works:
MINI recommends AKI 93.
Refuel with this gasoline to achieve the
rated performance and consumption values.
Minimum fuel grade
MINI recommends AKI 89.
John Cooper Works:
MINI recommends AKI 91.
If you use gasoline with this minimum AKI
Rating, the engine may produce knocking
sounds when starting at high external tem-
peratures. This has no effect on the engine
life.
