Your vehicle is designed to use unleaded gas- oline only. It is equipped with a fuel fillertube especially designed to accept only a small diameter unlead
ed gasoline dispensing
nozzle. In the United States, fuel suppliers are required by law to add detergents to their gas-
oline to minimize fuel-injector fouling and minimize intake-valve deposits. Detergent gasoline helps keep your engine in tune and your emission-control system working prop-erly. Your vehicle is designed to operate on pre- mium grade unleaded gasoline having a mini-mum octane number of 93 [(MON+RON)/2] or higher for optimum performance. In case premium grade unleaded gasoline 93[(MON+RON)/2] is not available, unleaded gasoline rating of 91 [(MON+RON)/2] can be used. However, the performance level isreduced. In order to maintain exhaust system durabil- ity, premium unleaded gasoline having anoctane number of at least 91 [(MON+RON)/2] must be used If the premium grade unleaded gasoline rat-ing of 91 [(MON+RON)/2] or higher is not available on journey, etc., regular unleaded gasoline having an octane number of 87[(MON+RON)/2] can be used temporarily as an emergency measure.

Gasoline sold at some service stations con- tains oxygenates such as ethanol, althoughthe oxygenates may not be identified by those names. Oxygenates are required in some areas of the country. Such fuel can be used inyour vehicle. A mixture of up to 10 % ethanol (grain alco- hol) and 90 % unleaded gasoline may be usedin your vehicle, provided the octane number is at least as high as that recommended for unleaded gasoline. Do not operate your vehicle on gasoline con- taining methanol (wood alcohol). Using thistype of alcohol could adversely affect the vehicle’s performance and damage critical parts of the vehicle’s fuel system.
