SUBJECT
Approved Diesel Fuel
MODEL
All with BMW Advanced Diesel engines
SITUATION
Some filling stations in specific states offer biodiesel blends greater than 5% (B10 or greater). BMW only approves blends up to
5% (maximum B5).
INFORMATION
Current BMW vehicles with advanced diesel technology were designed and tested to run on Ultralow sulfur diesel fuel (ULSD)
with a biodiesel content of 5% or lower. This also meets ASTM D6751 specification. The use of any other fuel may damage the
highpressure fuel system components; internal engine damage could also occur. Any resulting failures/damage would not be
covered under the BMW limited warranty.
The diesel pump must have this label (ULSD).
Not to be used in BMW vehicles.
A few states, such as Illinois, have filling stations that now offer biodiesel blends greater than B5 (biodiesel blends greater than
5%); these pumps are clearly labeled. However, up to 50% of Illinois diesel filling stations currently offer diesel that meets the
BMW requirements.
Pumps dispensing up to B5 are not required to be labeled by the Federal Trade Commission.
BMW is aware of the changing environment in biodiesel availability, and is monitoring statespecific requirements. We will keep
you informed of any future developments.
In the meantime, owners should be advised to only use diesel fuel with a maximum B5 content.
