Gas prices in my area of the Chicago burbs have gone up to $4.40 for regular at some stations. I’m giving E85 another try. I got it for $3.50 on Tuesday locally and also used it for part of my trip home Monday (got it in Indiana). I have a 2018 Ford Escape that is marked E85 on the gas cap, so my vehicle has no issues with it. At this point, no decrease in MPG and the Scuba Sherpa runs like usual. I’ll report back on how this experiment goes. I realize E85 is most widely available in the Midwest (it’s 51-83% ethanol from corn).
