I don't know about anyone else, but my milage sucks on the '05 Lariat 4X4 with 3.73 gears. Everyday I drive 30 miles round trip to work on a 4 lane with the cruise locked on 60 mph and only get 16.4 mpg. The best I have got on a long trip is 17.8 mpg that was after putting a Roush exhaust on it. Pulling my car trailer I get 15 mpg. I expected a little better overall.

I do 53 miles 1 way, all open road except for the last 5. My trip computer says 18.1 right now. It bounces between 17.8 to a high of 18.4. It's mostly 18.0 to 18.1. I think a lot has to do with seasonal formulation of fuel, outside temps and terrain.

My Lariat does have the 3.73:1 LS.

I found my trip computer to be off as much as 1 mpg. When ever I get gas I always fill it until the pump shuts off, then calculate my milage.

Around town only 15-16,mixed driving 18,highway 19-22mpg. In your '05 Lariat 4X4 with 3.73 gears 4 people in it most of the time. Going over the pass getting back to Reno 14-15 mpg. Thats driving 65-70mph with or without A/C on. I'm amazed how good the gas milage is for a such a big truck. I guess it's all how you look at it.

Scoop...have you done anything to the motor to get 19-22 mpg? Our combos are identical, I'd almost kill to get 18 mpg.

Mike,I haven't changed a thing. I do have 22000 miles on it now. I did notice the milage went up alittle after the first 10,000 miles or more. I do change the oil every 3000 miles and have changed the air filter twice since new. I have read that these trucks can vary 1-3mpg from each other. I don't use the computer to figure milage either.

You guys are all kickin' my butt. I have a '98 4x4 with the 5.4L. I get 13-14 back and forth to work with just me, pulling nothing! Luckily, it's only 12 miles each way.

My 05 supercab has only 1100 miles on it and it has gotten 16.6 on the last 3 tanks. I put on a toneau cover and they claim a mileage improvement of 10%. I say that is a little high,and am hopeful for 1 mpg. That's what I got in my last truck.

I'll spend the 16.6 for the 300 HP. Especially since my last truck was getting 13-14 mpg,and this truck is almost 1k lbs heavier.

BTW, my wife's 2000 Explorer with a 4.0 OHV is getting 18.1 mpg. I think I'm geting a heck of a buy.

All that's done to mine is a dealer installed soft tonneau. With the tonneau off, it feels like I'm pulling two water skiers. Maybe it's me and wishful thinking that I can tell the difference.

My 5.4 F150 regular cab only averages around 12 MPG.

Then again, it does have a s/c on it and a lead foot on the gas!

Been there, did that, got the tee shirt.

You're confusing miles per gallon with SMILES per gallon (but that's understandable).

Not me baby, I smile all day long!

Not only does this Lightning get better gas mileage than the 5.0L '94 F150 extended cab I used to drive, but I accept the MPG as a good trade off for the fun I have with my L.

Yeah, my 98 4x4 got about 12 running back and forth to work. 6 miles on the highway and 3 or so in town. Ran great, but I traded for the Ranger for economy. It gets 20.

I rented a 2006 Mark LT supercrew for a quick work trip. I drove 400miles and it had an average of 18.5mpg.
BTW beside the grill and rims there is nothing different between that and the Ford truck. I thought for sure they would have done something to make it stand apart?

I want another full size truck so bad I can't stand it.
But, my 4 cylinder Ranger gets 30mpg.
Only until I hook the trailer and 4 wheelers up, then it gets a strained 20mpg at a maximum 65 mph. Trailer and 2 four wheelers weighs 2100 pounds. I really NEED a full size truck.

With a 65 mile round trip every day I will stick with the Ranger a while longer.

They sure did! They took the extra money you pay and give you a badge engineered truck.

IMHO I like the FX4 trim better than the Lincoln LT or the King Ranch. The power folding mirrors are a bit much.

I liked the FX4 trim too it's more truck like,but we got the Lariat. BTW I love those heated seats more then I thought I would.
The FX4 had a firmer ride which I liked better. Just matter of changing the shocks. The king ranch was too much for me too.

My last tank was 17.4 with mixed driving,on a truck with 1800 miles on it. That's a good thing,'cause fuel prices are going up hard and fast.

I average 12mpg combined hwy/city. Get about 15mph pure hwy. 02 F-250 W/3.73's and a 5.4L. These are 6000lb trucks, shaped like a brick, they will not get good mileage.

I took my truck on a little trip last week,and it got 18.7 mpg. The 3 valve 5.4 is amazing. Today Iused it to haul the glass for Steve's Mach1 from the body shop. The rear window rode comfortably in the back seat.

I get the same thing with my 99 but it's about 20 miles one way with the highway/city mileage being about 50:50

On our recent camping trip to Yosemite, I got 18.4MPG, 90% freeway, constant speed, loaded with camping equipment and a passenger.

That's better than I thought she'd get, that's for sure, because I still got on her hard! (I love that blower whine!!)

I gotta say Steve, things have been kinda rosey for me recently. We finally seem to be getting a handle on the debt we've been carrying for all these years.

But regarding the gas mileage, that 18.4MPG surprised me. Usually on long trips, I get high 16's, low 17's at 75 to 80mph. The only change this time was a lower speed because Renee was towing with the Excursion, so we kept it between 60 and 65mph.

I?m now getting 14-15 with the same driving habits and conditions. I was going to see if the Royal Purple oil would give me a boost in mileage but the experiment is now screwed. NJ now using a 10% ethanol blend for gas. Now I don?t know if it?s the oil, fuel or the combination.

My truck has 5K on it now,and it got 18.5 on the last tankfull. That was with it at the dealer running for 1 1/2 hours with the AC on!

The AC doesn't leave puddles on the ground when I use it. The service writer said the drain was ok,and the new{04-up} trucks drip on the exhaust,so it will evaporate. Anyone else notice this? OH yeah,they had to shim the rear for a pinion angle clunk.

Pulling up to the driveway to stop and then back in, it'll leave a trail of water drops about 6-8 feet long. Once backed in, no puddles.

As of the ride in today, 18.3 mpg.

If anything,I would want it on the ground instead. I guess I'll have to fix it myself. The condensation from the ac needs to be removed from the plenum. That way there won't be mold growing in it.

I know what you mean. Mine was the way it is now all last summer too. I never really gave it much thought since it never has smelled moldy or given off any other funky stink. Mind you, it's like the Mekong Delta here during the summer.

Next time I drain the oil, I'll have a look up there and see what gives. The lower passenger side firewall would be the first place to look, right?
