I average about 11.6-11.8 on my long term fuel economy with a mix of daily driving, towing, etc. Would LOVE for that number to jump up a couple mpg.
While I did not buy the Raptor to be a fuel efficient vehicle by any means, having better MPG is a nice thing. Having a crappy MPG seems to make some guys feel manlier. All it is doing is throwing money down the drain. I'll still buy a vehicle with crappy mpg if I like the vehicle (....ie RAPTOR lol), but I will always prefer having a better mpg if possible. It's having your cake and eating it too!
10k miles a year at 11.5 mpg is ~870 gallons of fuel. At $2/gal that's $1740 in fuel for the year, at $3/gal that's $2610 in fuel for the year.
Now bump that to 13.5 mpg, that's 740 gallons of fuel. $1480/yr at $2/gal, $2220/yr at $3/gal.
So just bumping from a ****** 11.5 to a slightly less ****** 13.5 with 500 lbs less weight, an ecoboost, and a 10 speed trans, which I think is realistic, that saves me between $260 and $390 a year. So while it's not THOUSANDS of dollars, which is why I don't mind having a poor-mpg vehicle, it is SOMETHING, basically a FREE mod per year. I've had my Raptor 3 years now, and if it had 2 mpg better I could have had an intake, tune, and probably another mod or two in what I could have saved in gas when it was closer to $4/gal and above most of the time I've had it, if it had 2 mpg better lol.
