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).
