Another visit to the GetGo station

I stopped today at the Wexford GetGo station after completing my last dog training class in nearby Cranberry Twp. The price per gallon had dropped 2 cents a gallon since last weekend. I did not need too much fuel so I added 0.9 gallons of E85 and then 4.0 gallons of E10. My tank was not full after this addition. I then drove home thru 3 inches of snow with an outdoor temperature of 26 degree. My Ford Dash reported a 30.0 mpg average since the fillup which is 3+ mpg less than a week ago. However, it is nearly 10 degree colder with snow and a wet road surface today that can partially explain the drop in mileage. I am going to be taking off my Eco-Plus tire (stock) and putting on my Goodyear Forenta Triple Tread (winter tires) in the next few days. I got a trip to Wisconsin planned at the end of the month and I should be able to drive the complete way on intermediate blends of ethanol.
