Winter driving will net reduced fuel economy due to the colder temperatures vs summer. There are many variables that factor into this. The air is more dense which equals more air so more fuel. Your vehicle is also suffers from increased drag in the winter. I would also imagine that you let it warm up longer in the winter. These are a few of the factors that play into poorer winter fuel economy.

 

Not to mention that fuel is formulated differently for winter and yields lower mileage.

 

Do the math on paper using the same odometer reading and gallons quantity on your fuel receipt. It can easily be 1.5 mpg different, and not in your favor. Hence "lie-O-meter".

 

OK, I topped off the tank just now, since I'm going on a long trip tomorrow. 20.7 mpg, calculated from the actual mileage and gallons pumped. I use fuelly now, instead of calculating and keeping a log book. This tank was around 80% highway/country road and 20% city mileage, which is why it was much higher than previous fillups. I'll note that the dash read 21.6 at the time of the fillup. It's generally been about 1/2 mpg above the actual calculated mileage, which is what I experienced in my Escape as well in the past.

I'm pretty pleased with that mileage. We'll see how it fares tomorrow on the long trip.

 

'18 SCREW with MTT package & 20'' wheels, getting 13.56 mpg around town. was definitely hoping for more than that. truck has 100ish miles on it.

 

Averaging between 17.2 and 19.1 here since new on mixed use. Hopefully it will improve a bit on warmer season gas and warmer weather in the spring!

 

20.2 on the last fill up, 18.4 overall. 1774 miles on it.

 

I've recently picked up a clean, one-owner 2011 with 4x4 and the 5.0 engine. So far, I'm averaging 16ish around town, and 19 on the highway. I've been pleased with that. My last vehicle was a Honda Ridgeline that only got 15 mpg, even though it was smaller and only had a v6

 

I use Fuelly to keep track of fill-ups. I've used it for about 7 years. Most forums allow the banner in your signature, but on here, it won't show the image, just the link, so you have to click it to see the banner. I like it because it's a game to get the mpgs higher, plus it gives you all kinds of long term information such as how much you spent on fuel for a year, trends in mpgs, etc.

 

Today Currently showing about 18.7 on winter blend. This Pic was taken mid summer at 90+ degrees. Running thru raleigh area on I40 around 60 mph. One time occurrence....
