According to the owner's manual, "Fuels with a maximum ethanol content of 25%, may be used for refueling".

Which I think means that if you want 25% in your tank, you would have to have 12.5gal of 91oct (w/ e10) and then fill it up with e85 (no more than 3.1 gal). Then again, last time I did algebra was in high school
