Ethanol free?

[Aarlin303]

I'm wondering if I can run 87 octane ethanol free gas in my 2018 ex hatch, with a hondata tune. I have no problem buying 91 Oct with 10% ethanol but I run ethanol free in my other vehicles and didn't know if it was foolish to do so with this car. I live at 5,280 ft if that matters.... Thx!

You could but its recommended that you run 91 or higher for the best performance

Thanks, wasn't sure if the no ethanol would offset the difference in octane or not
