Fuels containing alcohol
Caution: Take care not to spill fuel
during refuelling. Fuel containing
alcohol can cause paint damage,
which may not be covered under the
warranty.
Some fuel suppliers sell fuel containing
alcohol without advertising its presence.
Where uncertainty exists check with the
service station operator.
Note: Some difficulty in starting may be
encountered when using alcohol blended
fuel.
Ethanol
Fuels containing up to 10 per cent
ethanol (grain alcohol) may be used.
Ensure the fuel has octane ratings no
lower than those recommended for
unleaded fuel. Most drivers will not
notice any operating difference with fuel
containing ethanol. If a difference is
detected, the use of conventional
unleaded fuel should be resumed. Methanol
Some fuels contain methanol (methyl or
wood alcohol). If you use fuels containing
methanol the fuels must also contain
co-solvents and corrosion inhibitors for
methanol. Also, do not use fuels that
contain more than three per cent
methanol even if they
contain co-solvents
and corrosion inhibitors. Fuel system
damage or vehicle performance problems
resulting from the use of such fuels is not
the responsibility of Jaguar Cars Limited,
and may not be covered under the
warranty.
Methyl Tertiary Butyl Ether (MTBE)
Unleaded fuel containing an oxygenate
known as MTBE can be used provided the
ratio of MTBE to conventional fuel does
not exceed 15 per cent.
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.
