CITROEN DS3 Handbook page 193

Fuel used for petrol engines
The petrol engines are compatible with
E10 bio-petrol (containing 10 % ethanol),
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 the DS3 RaCING, CITRoËN
strongly recommends the use of
98 RON unleaded petrol to ensure
optimum operation of the engine (refer
to the label inside the fuel filler flap).
Fuel used for diesel
engines
The Diesel engines are perfectly with biofuels
which conform to current and future European
standards (Diesel fuel which complies with
standard 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 subject to strict
application of the special servicing conditions
indicated in the maintenance and warranty
guide. Contact a CITROËN dealer or a qualified
workshop.
The use of any other type of (bio)fuel
(vegetable or animal oils, pure or diluted,
domestic fuel...) is strictly prohibited (risk of
damage to the engine and fuel system).
