On a side note, I just filled up with Shell 91 V-Power (no ethanol) and I'll see how I do with some mixed driving. Approx -5c outside.
No, not all 2012 Job 2, or 2013 Focus models are flex fuel, as there is such a thing as the California emissions and or the P-ZEV models with two catalysts which are not compatible with ethanol blends greater than 10-15%.
