The Marathon at the corner of SR 26 & US 31 in Kokomo, IN had only regular listed yesterday evening. I know they carry all three grades, and I believe diesel, too. https://www.waze.com/editor/?zoom=5&lat ... 3,16483962
I note there's no address for this station, either, though I've seen them in others screen caps. Actually, I don't recall seeing addresses for any of the stations I've updated here in Central Indiana.
