There is an app for your phone called "Pure Gas" that will list gas stations near you that sell non-ethanol gas. I was told by an old school mechanic (which fits the description for most of this group) that it is more important to have a zinc additive in your oil than it is to have a lead additive in your gas. If you have a rebuilt carburetor the ethanol is probably not an issue as long as you don't let gas sit in the truck for long periods of time, such as winter storage.
