FUEL
Vehicles with a petrol engine
Use only high quality fuel according
to specification EN 228 or
equivalent specification.
Unleaded fuel
(minimum 93/95 octane)
Vehicles with a petrol engine have a
fuel filler neck with a narrow
opening which is compatible only
with the nozzle on unleaded fuel
pumps.
If the vehicle has a petrol
engine always use
unleaded fuel. Fuel containing
lead will cause permanent
damage to the catalytic converter
and HO2S sensor (heated exhaust
gas oxygen sensor). Ford can
accept no responsibility for
damage caused by using leaded
fuel. Although such damage is not
covered by warranty, please
contact the nearest expert
immediately if you have
inadvertently added leaded fuel.
Ford authorized repairers are
recommended.
Vehicles with a diesel engine
Use only high quality fuel according
to specification EN 590 or
equivalent specification.
Capacities and specifications
Do not use RME (bio diesel)
except in the case of those
proprietary diesel fuels which contain
a mix of up to 5% RME. Ford can
accept no responsibility for damage
caused by using RME (bio diesel) in
concentrations greater than 5%.
Do not use vegetable oil instead
of diesel. Ford can accept no
responsibilty for damage caused by
using vegetable oil at any concentration.
Prolonged use of additives to
prevent fuel waxing is not
recommended. Do not add kerosene/
paraffin or petrol to diesel fuels.
If you inadvertently fill your vehicle
with petrol instead of diesel, do not
attempt to start the engine. This may
lead to severe and costly damage
especially to TDCi engines. Ford can
accept no responsibility for any damage
caused by allowing the vehicle to
operate on petrol. Although such
damage is not covered by the warranty,
contact the nearest expert immediately.
Ford authorized repairs are
recommended.
Duratorq TDCi engines with
Stage IV emissions
When refuelling Duratorq TDCi
engines with Stage IV emissions,
always refuel a minimum of
10 litres each time.
