There should be a sticker on the door for the gas that says E-85, typically right under where you set your cap to rest while you are pumping; at least this is the way it is on my wifes '03 Z71 Hoe(L59).

for most trucks, the 8th digit is a Z. Some trucks have yellow caps, some dont. Some have the e85 sticker on the inside gas door, some dont.
