From Ford Motor Company:
"EcoBoost is a family of turbocharged, direct injected gasoline engines produced by the Ford Motor Company. Engines equipped with EcoBoost technology are designed to deliver power and torque consistent with larger displacement, naturally aspirated engines while achieving approximately 20% better fuel efficiency and 15% reduced greenhouse emissions than these same engines. Relative to the power output and fuel efficiency of hybrid and diesel technologies, Ford sees EcoBoost as an affordable and versatile alternative and intends on using it extensively in future vehicle applications."

I'm with Outlaw329. I owned Chevy's for many years. I reluctantly bought a 1997 F150 Flareside 4.6L. And now I also have 160000. I replaced the tranny last year. That has been my biggest expense, and I did it as a precaution, it did not fail. This truck has never stranded me, I get 12-15 mpg average. I put better gears in the rear end for better towing (3.73). Before that the 3.08 gears were giving me 14-17 mpg. For improving mileage, go nitrogen in the tires, cover the bed, glue a raw egg to the gas pedal once a week, low friction oil, you can get that truck up to 17-18.... Good luck and enjoy the reliability you invested in..

I have a 2001 F 150 supercrew 4X4 and get about 14/15 depending on how I drive, but during the winter get about 12 mpg. I did not buy this truck to resell but for being dependable. I came over from driving chevys all my life and glad that I decided to make the change. I run Amsoil from front to rear and use lucas upper cyclinder lube and have added an air filter from K&N. I am up to about 160000 miles.

First, you did not specify exactly what type of fuel mileage you were quoting. I am going to take it that it your overall, combined fuel mileage. Based on that, 13.5 - 15.0 MPG is about all you are going to get from your 2004 SuperCrew. The 5.4L engine just does not have torque to get all that weight moving, without using fuel. This is where a large percentage of the fuel mileage is lost. The 5.4 is a very good engine, and it is the same concept GM is now/has been using with their 5.3L (which is based on the ol' 327 cu. in. block) engine.
There are some things you can do to squeeze some more MPGs out of it. First is to use Top Tier fuels, either by themselves or in ratios to high-quality discount generic fuel. That will clean out the entire fuel system and you will NEVER need to use additives. This may improve your fuel mileage some, and if not, will improve performance.
If you are already using those fuels and/or fuel system is clean, top-notch and not an issue, then you can try using Synthethic lubricants in the entire drivetrain. This includes diffs, transfer case and engine. If you have considerable miles on the truck, consult with a Knowledgeable Mechanic (which does not necessarily mean a Ford Service Tech, but does not exclude them either, as many independent ASE Master Techs know more than dealers) before switching over to synthetics. The penetrating and lubrication qualities of syn fluids are so good, that they can seep past hardened gaskets and seals, which then gives you fluid leak problems.
You can free up its breathing, but we have found that this typically only improves performance, torque and towing abilities. Fuel mileage increase is neglible.
If you go for a major change, it can make a BIG difference. Here is what we did.
We had a loaded 2005 F-150 SuperCrew with a 5.4L. One of our ranch hands had a 2003 F-150 he had bought used with high mileage, which turned out to be very abused. His engine blew and he got lucky. We were thinking about upgrades, so we decided to go ahead and took pity on him. We swapped out our good 5.4L and trans into his truck for work he did. We took his old engine and trans to be our cores. We installed a custom built Ford 355 engine with custom computer and controller, mated to a wicked custom B&W 5-spd auto trans and transfer case. We also changed out the rest of drivetrain to match the increased HP and torque. While we were at it, we redid the front suspension with teflon bushings and tubular components. Of course, syn fluids all around.
While the cost of parts alone was upwards of 6 Grand, the truck is one ass-kickin mule. While you would have to justify the cost versus the benefits derived, fuel mileage is now between 17.5 and 18.3 MPG on a consistent overall average. We have gotten over 22 on the highway, even towing a 10,000 lb. fully loaded weight trailer. The reason why is the engine and drivetrain. The high-perf 355 has that low end torque to move that weight without expending a lot of fuel and energy to do so. Even when I put my foot into it, it still gets better than 12.

This is why the market value of these F150s used ones are so low but they are fairly reliable work trucks

gbryceMO, you need to talk to some of the people on the forum, acetone for better mileage. Search it on the internet. I don't have a vehicle with a carb, but they are suppose to get even better mileage. I am sure you can find gas without ethanol in MO. I live in Illinois and I can find it. You will get a little better mileage with straight gas, no ethanol.
I use acetone and xylene, I haven't bought the 2 cycle oil to mix yet, but I am going to soon.

Ford trucks have never been know to make good mileage. I know alot of people with trucks like yours and their mileage is about the same.

I'm surprised at that mileage. We have a 2006 diesel 4x4 6.0 diesel and we get 18 highway and 13 city.

EPA estimated mpg of 13 city and 17 highway or 11 city and 15 highway (not a supercrew)A 2005, like yours, averaged 14 city/18 highway for an average of 16 mpg on the F-150 link. You may want to slide your cursor over "Home" in the above toolbar. One of the selections is "$ Fuel Saving Tips."

Check out www.fuelly.com and FuelEconomy.Gov
On Fuelly, you can filter results based on engine type and body style. According to the web site, the majority of users get 15 MPG in their V8-powered .F-150s
On the government website, you can see individuals' reported gas mileage, but it doesn't chart the results as Fuelly does.
