Quality of the fuel used for
petrol engines
The petrol engines are perfectly com-
patible with E10 or E24 type petrol
biofuels (containing 10 % or 24 % etha-
nol), conforming to European standards
EN 228 and EN 15376.
E85 type fuels (containing up to 85 %
ethanol) are reserved exclusively for
vehicles marketed for the use of this
type of fuel (BioFlex vehicles). The
quality of the ethanol must comply with
European standard EN 15293.
For Brazil only, special vehicles are
marketed to run on fuels containing up
to 100 % ethanol (E100 type).
Quality of the fuel used for
Diesel engines
The Diesel engines are perfectly com-
patible with biofuels which conform to
current and future European standards
(Diesel fuel which complies with stan-
dard EN 590 mixed with a biofuel which
complies with standard EN 14214)
available at the pumps (containing up
to 7 % Fatty Acid Methyl Ester).
The B30 biofuel can be used in certain
Diesel engines; however, this use is sub-
ject to strict application of the special ser-
vicing conditions. Contact a CITROËN
dealer or a qualifi ed workshop.
The use of any other type of (bio)fuel
(vegetable or animal oils, pure or dilut-
ed, domestic fuel...) is strictly prohibited
(risk of damage to the engine and fuel
system).
