INFORMATION
FUEL REQUIREMENTS
Catalyst vehicles
Vehicles equipped with catalytic converter are designed to use ONLY unleaded fuel. Unleaded fuel must be used
for the emission control system to operate properly. Its use will also reduce spark plug fouling, exhaust system
corrosion and engine oil deterioration.
Using fuel that contains lead will result in damage to the emission control system and could result in loss of
warranty coverage. The effectiveness of the catalysts in the catalytic converters will be seriously impaired if leaded
fuel is used. The vehicle is equipped with an electronic fuel injection system, which includes two oxygen sensors
(4 oxygen sensors on NAS vehicles). Leaded fuel will damage the sensors, and will deteriorate the emission
control system.
Regulations require that pumps delivering unleaded fuel be labelled UNLEADED. Only these pumps have nozzles
which fit the filler neck of the vehicle fuel tank.
RECOMMENDED FUEL
Petrol engines
Use petrol conforming to European standard EN228
Low compression engines
With catalytic converter
91 RON minimum unleaded
...........................................
Without catalytic converter
4.0 litre
91 RON minimum unleaded or 91 RON minimum
............................................................
leaded
4.6 litre
91 RON minimum unleaded or 91 RON minimum
............................................................
leaded
High compression engines
95 RON minimum unleaded
...............................................
NOTE: It is possible to use unleaded fuel with a 91 RON minimum octane rating for high
compression engines, but performance will be adversely affected.
Using fuel with an octane rating lower than stated above could seriously impair vehicle performance.
Diesel engines
Diesel fuel to European standard EN 590; minimum
................................................................ Cetane No. 45
In the interests of optimum vehicle performance, the use of oxygenated fuels such as blends of methanol/gasoline
or ethanol/gasoline (e.g. ’Gasohol’) is not recommended. If oxygenated fuels are to be used, be aware of the
following maximum limits for the percentage of fuel additive that is allowed in the relevant markets:
NAS specification:
Methyl Tertiary Butyl Ether (MTBE)
15%
.................................
Ethyl Tertiary Butyl Ether (ETBE)
15%
.....................................
Ethanol (Ethyl or grain alcohol)
10%
........................................
CAUTION: Wherever possible, avoid using fuel containing Methanol
