must be formulated properly for your climate according
to ASTM specification D 5798. If you have trouble

starting on E 85, it may be because your E
not properly formulated for your climate. If this
happens, switching to gasoline or adding gasoline to
your fuel tank may improve starting. Your vehicle is
designed to accommodate a mixture of gasoline and
-
E 85 fuel. For good starting and heater efficiency below
32 _ F (0 _ C), the fuel mix in the fuel tank should contain
no more than 70% ethanol.

need to refill your fuel tank more often when using E
than when you're using gasoline. Use regular gasoline
when pulling a trailer. For payload capacity with ethanol
fuel see "Loading Your Vehicle" in the Index.
