jeepn30 7 Report post Posted December 24, 2017 This store just opened 12/23/17. As I was getting fuel in my Tesla (for my riding mower, which feels weird driving an electric car into a gas station), I saw that this Casey's has E85 as well as E15. E85 was 1.61, while regular was 2.41, and E15 was 2.36. The price board showed E15 and ethanol free premium (which theirs was only 91 octane), but no mention of E85 on it, which is somewhat disturbing. The address of this store is 425 Beloit Rd, Belvidere, IL 61008. I don't think many Casey's carry E85. Share this post Link to post Share on other sites
