The engine is knock controlled. Therefore, you  
can refuel with different gasoline qualities.  
Vehicle equipment  
This chapter describes all series equipment as  
well as country-specific and special equipment  
offered for this model series.Therefore, it also  
describes equipment that may not be found in  
your vehicle, for instance due to the selected  
special equipment or the country version. This  
also applies to safety-related functions and sys‐  
tems.  
Recommended fuel quality  
BMW recommends AKI 91.  
Minimum fuel grade  
BMW recommends AKI 89.  
Minimum fuel grade  
Do not fill up with fuel below the specified  
minimum quality; otherwise, the engine may not  
run properly.◀  
Fuel quality  
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.  
Gasoline  
For the best fuel economy, the gasoline should  
be sulfur-free or very low in sulfur content.  
Do not use fuels that are labeled at the fuel pump  
as containing metals.  
Minimum fuel grade  
The use of poor-quality fuels may result in  
harmful engine deposits or damage. Addition‐  
ally, problems relating to drivability, starting and  
stalling, especially under certain environmental  
conditions such as high ambient temperature  
and high altitude, may occur.  
Only refuel with lead-free gasoline without  
metal additives  
Do not refuel with leaded gasoline or gasoline  
with metal additives, e. g., manganese or iron;  
otherwise, the catalytic converter and other  
components will be permanently damaged.◀  
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, it is highly recommended to purchase  
gasoline from BP or Top Tier retailers.  
Fuels with a maximum ethanol content of 10 %,  
i.e., E10, may be used for refueling.  
The ethanol should fulfill the following quality  
standards:  
US: ASTM 4806–xx  
Failure to comply with these recommendations  
may result in the need for unscheduled mainte‐  
nance.◀  
CAN: CGSB-3.511–xx  
xx: always adhere to the currently applicable  
standard.  
Do not refuel with ethanol E85  
Do not refuel with E85, i.e., fuel with an  
ethanol content of 85 %, or with Flex Fuel, as this  
would damage the engine and fuel supply sys‐  
tem.◀
