Fuel recommendation

General information
Depending on the region, many filling stations sell fuel that has been customized to winter or summer conditions. Fuel that is available in winter, for instance helps make a cold start easier.

Gasoline

General information
For the best fuel efficiency, the gasoline should be sulfur-free or very low in sulfur content.
Fuels that are marked on the gas pump as containing metal must not be used.
Fuels with a maximum ethanol content of 25 %, i. e. E10 or E25 may be used for refueling.

Ethanol should meet the following quality standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current standard in each case.

Safety information
CAUTION
The use of poor-quality fuels may result in harmful engine deposits or damage. Additionally, problems relating to drivability, starting, and stalling, especially under certain environmental conditions such as high ambient temperature and high altitude, 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 tanks fills. To avoid harmful engine deposits, it is highly recommended to purchase gasoline from Top Tier retailers.
Failure to comply with these recommendations may result in the need for additional maintenance.

NOTICE
Even small quantities of the wrong fuel or wrong fuel additives can damage the fuel system and engine. Furthermore, the catalytic converter is permanently damaged. There is a risk of damage to property, among other potential damage. Do not refuel or add the following in the case of gasoline engines:

  • Leaded gasoline.
    Metallic additives, for instance, manganese or iron.
    Do not press the Start/Stop button after refueling with the wrong fuel. Contact a dealer’s service center or another qualified service center or repair shop.

NOTICE
Fuel that does not comply with the minimum quality can compromise engine function or cause engine damage. There is a risk of dam‐age to property, among other potential dam‐age. Do not fill with fuel that does not comply with the minimum quality.

NOTICE
Incorrect fuels can damage the fuel system and the engine. There is a risk of damage to property, among other potential damage. Do not use fuels with a higher ethanol content than recommended. Do not refuel with fuels containing methanol, e.g. M5 to M100.

Recommended gas quality
BMW recommends AKI 91.
M Performance model:
BMW recommends AKI 93.
Refuel with this gasoline to achieve the rated performance and consumption values.

Minimum fuel grade
BMW recommends AKI 89.
If you use gasoline with this minimum AKI Rating, the engine may produce knocking sounds when starting at high external temperatures. This has no effect on the engine life.

Engine oil

General information
The engine oil consumption is dependent on your driving style and driving conditions.
Therefore, regularly check the engine oil level after refueling by taking a detailed measurement.
The engine oil consumption can increase in the following situations, for instance:

  • Sporty driving style.
    Break-in of the engine.
    Idle operation of the engine.
    With the use of engine oil types that are classified as not suitable.
  • Different Check Control messages appear on the Control Display depending on the engine oil level.
  • Safety information
  • NOTICE
    An engine oil level that is too low causes engine damage. There is a risk of damage to property, among other potential damage. Immediately add engine oil.
  • NOTICE
    Too much engine oil can damage the engine or the catalytic converter. There is a risk of dam‐age to property, among other potential damage. Do not add too much engine oil. When too much engine oil is added, have the engine oil level corrected by a dealer’s service center or another qualified service center or repair shop.

Electronic oil measurement

General information
The electronic oil measurement has two measuring principles:

Monitoring.
Detailed measurement.
When making frequent short-distance trips or using a sporty driving style, for instance when taking curves aggressively, regularly perform a detailed measurement.
