QUALITY OF THE FUEL USED FOR PETROL

The petrol engines are perfectly compatible with E10 or E24 type petrol
biofuels (containing 10 % or 24 % 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 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 compatible 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.
Contact a PEUGEOT dealer or a qualifi ed 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).
