Do not use any fuel labeled E85 or
FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by
volume.
Use regular unleaded gasoline meeting
ASTM specification D4814 with a
posted octane rating of 87 or higher.
Do not use gasoline with a posted
octane rating of less than 87, as this
may cause engine knock and will lower
fuel economy.
