14.1 MPG is probably as good as it is going to get

You have to drive with an egg under the gas pedal, going downhill with the wind at your back with over inflated tires to get the city mpg on the sticker....highway est is more doable.

Autocrossing or at the track and ..............let's just skip discussing fuel mileage,ha!

I haven't really measured on the track except in gross terms. I can manage 3 25-minute sessions on a full tank, that's about it. By the end of the 3rd session, my low gas light will be on and saying I have like 10 miles left lol.

At Sears Point, mostly right handers, I was having inconsistent readings probably due to the saddle tanks. At the end of one session it showed over 3/4 full then I did a lap around the parking lot (left turns) and it shot down to under 1/2. I try to keep it over 3/4 for that reason.

On my way home from Lake Tahoe yesterday I filled up in Truckee. I drove 86 miles home and for fun decided to fill up to see what my fuel mileage was. I was going mostly downhill and was cruising around 80 mph with a couple of blasts to 100 so I wasn't trying to get good mileage. When I filled up I put in 3.3 gallons so that’s 26.06 mpg. So Ford did tell the truth about the highway mileage but left out the downhill part.

Nice! I used to share a cabin in Truckee years ago. Must have been a beautiful drive. Jealous!

I was getting 8 mpg for the first week I had the car. Now I get 12-13 driving normally. I can average 20 in 6th gear on the highway, but if I go autoxing or canyon driving (both an hour away on the highway) I can get my average for the trip back to normal.

After 650 miles. 21.6 AVG. 2013 Boss.

 

[killerwill13]

Im driving around town and I just hit 715 miles and Im still only averaging around 13.2 to 14.2

Im going to just tell myself this mostly contributed to break in miles and not the fact I rev it up quite a bit

 

[roketman]

I just refill when the gauge goes to E
Your feelings may vary…..

Roketman is right. We didn't buy our Bosses for gas mileage. If I ever start worrying about fuel efficiency, I'll drive my wife's Corolla.

I like Ford's EPA rating on the sticker.... Saves us from paying the gas guzzler tax, thereby leaving us more money to finance the real-world mpg!!

For me: 20 mpg highway (I love west Texas speed limits) and 17.5 mixed driving on my daily commute. About 3,000 miles on her so far.

444hp and no gas guzzler tax??!! Nice work, Ford!

I don't even look at it that field is always on blank. Just check it here and there too make sure it didn't take a nose dive. That would be a clue that something is amiss

What's even more insane is the '13 Shelby GT500 with 662 HP doesn't have a guzzler tax either...GO FORD!
