Anyone towing with a 2.7 EcoBoost?

Diesel is about 10 cents per gallon less than 87 octane in my area today. Prices fluctuate seasonally as well as with location and the breeze. Typically in winter, itguy08's statement applies, just not today in Michigan.

I was more interested in the MPG difference irrespective of the fuel cost. Fuel costs fluctuate and than there is the psychology of filling up less frequently even if the net cost is the same.
