in wi cenex gas 87 octane is stil ethanol free and my mpg confers. i used to have a problem with MAF METER and it would hesitate and miss. the mechanics diagnose it wrong five times(under warranty)before fixing it. I lived in iowa mn and wi. Tried all the gases. With sinclair premium 93 it would not hesitate. The only one close to this was Freedom premium. Tried SA, Shell, Mobil quick trip and kwik trip etc. Sinclair ruled and there is about three gas stations in my territory that carry it and i always make a point to be "low" when i am going thru those area. I do not know who pumps freedom
