FUEL REQUIREMENTS

2.7L Engines

Your vehicle is designed to meet all emis-
sions regulations and provide satisfactory
fuel economy and performance when us-
ing high quality unleaded gasoline having
an octane of 87.

3.5L and 5.7L Engines

The 3.5L and 5.7L engines are designed to
meet all emissions regulations and provide
satisfactory fuel economy and perfor-
mance when using high-quality unleaded
gasoline with an octane rating of 87 to 89.
The manufacturer recommends the use of

89-octane for optimum performance. The routine use of
premium gasoline is not recommended. The use of
premium gasoline will provide no benefit over high-
quality regular gasoline or mid-grade gasoline and in
some circumstances may result in poorer performance.
