FUEL REQUIREMENTS

3.6L Engine — If Equipped
This engine is designed to meet all emis-
sions regulations and provide excellent
fuel economy and performance when us-
ing high-quality unleaded "Regular" gaso-
line having an octane rating of 87 as speci-
fied by the (R+M)/2 method. The use of higher octane
"Premium" gasoline will not provide any benefit over
"Regular" gasoline in these engines.
While operating on gasoline with an octane number of
87, hearing a light knocking sound from the engine is not
a cause for concern. However, if the engine is heard
making a heavy knocking sound, see your dealer imme-
diately. Use of gasoline with an octane number lower
than 87 can cause engine failure and may void or not be
covered by the New Vehicle Limited Warranty.
