This may be a real dumb question but is there going to be a difference if I run 91 non ethanol fuel or 88 non ethanol fuel mixed with 110 to bring the octane to 91? Seems like the 110 may have different properties and/or the 88 is a crappier fuel not just octane wise. Probably wrong but my dilemma is that I can get 88 and race in town but would end up a bit more per gallon or drive 4 hours and fill my 55 gallon drum with 91. Any help is appreciated.
