MPGs thread gripe
OK OK so we've not got a few dozen of these going which is always the case. People posting wild claims of the 5.0 getting or beating the 2.7/3.5 EB in MPGs. This all in some lame effort to justify their engine purchase decision. Then we see folks comparing 2wd or 4wd, then what's your gear ratio... on and on and on..
The one thing that I've yet to see is where "you live" as a metric? This is also a crucial aspect as at sea level not only will you have more power but you will see better MPGs. It's a sad truth those of us at higher elevations have to deal with. If that's not the case then I have a turd for a truck because I rarely see over 20 mpg and my lifetime is 18.9. I also rarely get on it hard just normal every day driving. Sure most of it is city but of the 6k I've got on it now at 2k of that is hwy.
My truck is 4wd FX4 SCREW with stock everything that matters, my level kit changed nothing so I'm not counting it. I have 3.55 in the axles and based on that what I see others getting I'm being shorted about 2mpg's, does that sound about right?
I also drove a very comparable '14 F150 for a couple weeks with the 5.0 and it averaged about 16 and that's with same commute and driving. Anyhow, did I get a turd or what?

I think terrain plays a part in it too. In the northeast, there are endless rolling hills. I'm sure smarter people than me have looked at those numbers, but long flat drives seem to get noticeably better gas mileage than long gradual hills.
I know uphill/downhill usually even out, but I think it takes more fuel to maintain speed going uphill than you gain from long, low grade downhills unless maybe you just slide into neutral and coast.

3.5EB, 3.55, 20" stock rims, stock size BFG ko2.
12,000 miles
17.8 lifetime MPG
Best mileage, 65 mph on flat road near sea level with cruise control, 21.5 mpg.
My highway mileage is less than my 12' 3.5EB, but my city mileage is considerably better.

Also, winter blend fuel is starting to show up in some areas.

Where you live is one factor, how you drive is another.
5.0, 3.55 Platinum, stock - not lifted. Averaging 21 MPG after 2,300 miles on the truck. 70% highway driving on flat terrain and the rest typical city driving. I can easily get 23 MPG on a long trip (2+ hours) Elevation in my area is 180.60 m (592.52 ft).

I have a stock Lariat SCrew, 3.5EB, 4WD, 3.55 e-locker, with 20" wheels and I am getting 16.5 MPG at 500' elevation is near flat to slightly rolling terrain. Mix of back roads/highways/city traffic. I drive a little spirited at times but mostly just the cruise set at 50mph, 72 mph and city traffic. I have owned 2wd/4wd F150's with V8's and EBs from 2009 and up and have never gotten more than 17mpg unless I just reset the LieMeter while going 60mph for a long stretch. At 72mph, I get 15.9mpg like clockwork. With that said, I find it hard to believe that people saying "highway miles" is above 17mpg are going 72mph. My guess is "highway miles" = 55mph. Just my 2 cents on my mileage.
