    Can E-15 88 octane be used in my 2010 Prius?

    Toyota doesn't recommend more than 10% ethanol blend, page 570 of the Owner's Manual.

    My experience with E10-E15 is posted here, but this is the cliffs notes version. 45-47 mpg on E10-15. 60-61 mpg on E0. There is a premium price for no ethanol, but it’s worth it. Similar results on my non Prius auto as well. 12mpg to 16mpg. Just changing stations.
