Could approach $5?
Non-ethanol gas is already $5.19 here in HNL
Magic Island Petroleum in Honolulu. Notice the date in the lower right corner. Granted, this is marine fuel but it used to be cheaper than on-road fuel because there are no road taxes on it. I don't drive so I haven't been to a gas station for awhile and do not know what the current prices are for on-road fuels.
