Exactly, your EPA mileage numbers are based on 3.31s. So there is a difference of .24. The guys with 4x4 and 3.73s have a difference of .42. That's almost twice the difference between the rated gear set and what they have.

My truck is about as heavy as a F-150 will be and has 3.55s. I have a .24 difference in gear set but a ton more weight. If I hold the speeds to 68-70 or so on a flat road I will get 20+. Considering the difference in gears and weight that seems about right.

 

I understand what you are saying and knew that. My point I was trying to make is that many buyers are getting about 17 to 18 and bought the vehicle thinking they would get the 22 Ford was advertising. They don't do the research and are not as informed as some of us and they end up disappointed.

 

Gotcha, I think the other thing is the new F-150s put so much more info about the mileage at your finger tips than the previous ones did. Before the higher models had one screen that showed your average MPGs. The other ones did nothing unless you used pen and paper. Most people are too lazy to keep good enough records for the pen and paper to even be close to accurate. They might do a comparison every once in a while on a long trip over a few tanks of gas. The new trucks have an entire display that shows your instant fuel usage and your average with numbers that are accurate.

To the OP, buy a truck when you need one. I would only hold out for a year or so if I know what is coming will be much better. I did this with my current truck. I knew the '11s would have new motors and I held of till they were released. I even went so far as to stretch out how long I could get out of a set of tires. But I knew when the new model was coming and when I could get it. What you're talking about is waiting at least a year or more to find out what is coming then another year or so to get it. For me that's a long time to wait on a maybe.

 

I would love to get 17-18! I'm only averaging about 15 mpg's doing mostly highway driving. No where near the 21 hwy sticker rating. I have a '12 FX4 Eco Screw with about 2k miles, hope it gets better. I love the truck but the gas mileage is a real disappointment so far.

 

3300 miles.... 18.7mpg service life of the truck

Best fill-up = 20.3mpg (643 miles - highway)
Worst fill-up = 17.6mpg (291 miles - 40 city/ 60 hwy)

My 2010 averaged 16.8 for the life and around 16 flat in the winter.
My 2004 averaged 15 for the life and 14.5 in the winter.

I am happy.

 

yeah, i was never a member of its fan base either......

 

May be this is why the next gen. will have better milage:

"Ward's Auto reported that Ford’s next-generation F-Series full-size pickup truck, code-named P552, will feature extensive use of aluminum body panels including doors and fenders. This will be a first for the F-Series as in the current model, only the hood is crafted from the lightweight material."

"Doug Scott, the Detroit company's truck marketing manager told the news site that the Blue Oval is always looking for ways to improve its vehicles.
“We know our customers, and it’s all about the truck being a tool and they want it to be more productive and more efficient,” said Scott. “So we have to keep moving the needle if we want to be king of hill. We’re always looking at all the ways of doing that going forward and we have a great strategy.”
Ford's produce chief Derrick Kuzak has previously said that the company plans to shed up to 700 lbs. (318 kg) per model before 2019.

 

My EB is delivering the advertised numbers (Screw 4x4 3.55). I'm getting 15.4 in DC traffic and 21.5 over the road. No complaints here.

 

You have to understand what they are advertising. Before you buy and not be blinded by what you really own and rising gas prices. Advertised is a 2wd eco boost not 4WD and that is probably on a XL model which is lighter. The 4wd model is 21mpg highway. the 4wd model is advertised at 15/21 and I think you will find many people are doing just that. Yeah there are some saying they get horrible mileage, but I qeuestion their driving habits and or the terrain they are in. Or simply out of 100k of these made there are going to be a few that just dont perform.

Its like going to applebees for the 2 for $20 and expecting prime rib to be one of the options. Know what you are buying and dont be fooled by ads

 

My window sticker says "City MPG 15 Expected range for most drivers 12 to 18 MPG", so I'm in range there. It also says "Highway MPG 21 Expected range for most drivers 17 to 25 MPG Your actual mileage will vary depending on how you drive and maintain your vehicle" Again, I am in the range. Most ecoboost MPG numbers, even most of the so-called bad ones are within the ranges cited. But it is the 22 MPG number that gets hyped, gets the attention and is what everyone believes they should get. Almost nobody reads the fine print or expects to be lower than the bolded numbers.

 

The commercial on tv here claims the ecoboost gets 31 hwy mpg.
My raptor gets exactly what the sticker said. 14-16 mpg. But different engine comparison.

 

That's miles per IMPERIAL gallon, and you Canadians also have a completely different method to determine the advertised mileage. It's not even CLOSE to real world.

 

So here is my little bit... 11 EB w/3.15 rear 18" wheels with 9500 on the odo. last 363.miles burned 20.3 gal in 12hrs 17 minutes of driving average speed 29.54 mph "id call that city driving".. average 17.8 mpg.....

 

No, I wasn't. Did you see my followup post?

 

After the fact of course... better?
