BMW 5 Series: Fuel
Fuel recommendation
General information
Depending on the region, many gas 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 tank 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 unscheduled 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. 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
Incorrect fuels can damage the fuel system and the engine. There is a risk of damage to property.
Do not use fuels with a higher percentage of ethanol than recommended. Do not refuel with fuels containing methanol, e.g. M5 to M100.
NOTICE
Fuel that does not comply with the minimum quality can compromise engine function or cause engine damage. There is a risk of damage to property. Do not fill with fuel that does not comply with the minimum quality.
Recommended fuel grade
BMW recommends AKI 91.
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.
