Fuel and refuelling

Unleaded fuel
Unleaded fuel must be used for the emission
control system to operate properly. Its use will
also reduce spark plug f ouling, exhaust system
corrosion and engine oil deterioration.
Octane rating
The recommended unleade d fuel should have
an octane rating of 95 RON (Research Octane
Number) or higher. Howe ver, you may also use
unleaded fuel with a lower RON, but
performance will be reduced. The minimum
octane rating for fuel to be used is 91 RON.
Note: Using unleaded fuel wi th a lower octane
rating than recommended, can cause
persistent heavy engi ne knock (a metallic
rapping noise). If severe , this can lead to
engine damage.
If a heavy knock is dete cted, even when using
fuel to the recommended octane rating, or if
you hear knock while ho lding a steady speed
on level roads, consult your Dealer/Authorised
Repairer to have the problem corrected. Failure
to do so is misuse of the vehicle, for which
Jaguar Cars is not responsible. However,
occasional, light knock for a short time while
accelerating or driv ing up hill, may occur.
ALTERNATIVE FUELS FOR PETROL
ENGINES
Fuels containing alcohol
Some fuel suppliers sell fuel containing alcohol
without advertising its presence. Where
uncertainty exists, check with the service
centre operator. Note:
Some difficulty in starting may be
encountered when using alcohol blended fuel.
Ethanol
Fuels containing up to 10% Ethanol (grain
alcohol) may be used. Ensure that the fuel has
octane ratings no lower than those
recommended for unleaded fuel. Most drivers
will not notice any opera ting difference with
fuel containing Ethanol. If a difference is
detected, the use of c onventional unleaded fuel
should be resumed.
Methanol
Some fuels contain Meth anol (Methyl or wood
alcohol). If you use fuels containing Methanol
the fuels must also contain co-solvents and
corrosion inhibitors fo r Methanol. Also, do not
use fuels which contain more than 10%
Methanol even if they contain co-solvents and
corrosion inhibitors. Fuel system damage or
vehicle performance pr oblems resulting from
the use of such fuels is not the responsibility of
Jaguar, and may not be covered under the
warranty.
CAUTIONS
Fuel containing alc ohol can cause paint
damage, which may not be covered
under the warranty.
CAUTIONS
This vehicle is not suitable for use with
fuels containing more than 10%
Ethanol.
Do not use E85 fuels (85% Ethanol
content). Equipment necessary for the
use of fuels containing more than 10% Ethanol
is not fitted to this vehicle. If E85 fuels are
used, serious engine a nd fuels system damage
will occur.
CAUTION
Wherever possible avoid using fuel
containing Methanol.

Fuel and refuelling

Methyl Tertiary Butyl Ether (MTBE)
Unleaded fuel containing an oxygenate known
as MTBE can be used provided that the ratio of
MTBE to conventional fuel does not exceed
15%. MTBE is an Ether based compound
derived from Petroleum, which has been
specified by several refiners as the substance
to enhance the Octane rating of fuel.
Reformulated gasoline
Several petroleum comp anies have announced
the availability of reformulated fuels. These
fuels are specially formulated to further reduce
vehicle emissions. Jagua r fully supports all
efforts to protect and maintain ambient air
quality and encourages the use of reformulated
gasoline, where available.
DIESEL ENGINED VEHICLES
Use only high quality diesel fuel according to
EN590 or equivalent.
The quality of diesel fu el is variable, depending
on geographic location . Always use premium
or the highest quality fuel available in your
locality. High quality fuel ensures a longer life
for your engine components. Lower grade fuel
contains higher levels of sulphur, which is
detrimental to engine components. If low
quality fuel is used, light coloured smoke may
be evident at the exhaust.
Note: Jaguar vehicles ar e capable of running
with up to a 5% blend of bio-diesel, in
accordance with European Standard EN590. Prolonged use of additives is not
recommended. Do not add paraffin or petrol to
diesel fuels.
Winter grade diesel fuel
To make sure of relia
ble diesel engine
operation during cold seasonal periods, Winter
grade fuel must be used . This fuel is normally
available from fuel retailers during these
periods and the fuel companies adjust the fuel
quality to suit climatic conditions.
If the vehicle is not filled with Winter grade
diesel fuel, it is recommended that the engine
is idled for a period of over two minutes after
starting, to prevent fuel solidification during
operation.CAUTION
Do not use RME (bio-d iesel) except in
the case of those propr ietary diesel fuels
which contain a mix of up to 5%. Jaguar can
accept no responsibility for damage caused by
using RME in concentrat ions greater than 5%.
CAUTIONS
If you inadvertently fill your vehicle with
petrol instead of di esel, do not attempt
to start the engine. Contact your Dealer/
Authorised Repairer im mediately. Attempting
to start the engine with petrol in the fuel tank,
will cause extensive dama ge to the engine and
fuel system, which will not be covered by your
Jaguar warranty.
Jaguar cars can ac cept no responsibility
for any damage caused by running your
vehicle with petrol or ve getable oil in the fuel
tank.
