you couldnt push mine and get those MPG, however mine also had a 5th wheel and a tool box and back seat converted to sleeper. empty weight my truck was at 8500.
I got rid of it the otherday and got a new 250 diesel

Finally got a 600 mile tank!

Yesterday, I drove home from the Texas Panhandle and fueled up at the first Love's I came to on the Oklahoma side of the state line on I-40. I drove to about 20 miles west of St. Louis before I had to fill up again. 87 octane, and I didn't baby it at all. Average speed per the dash was 76 mph. Not towing but had a couple hundred pounds in the bed, plus an ARE Z-Series top, and me. Standard 60/65 psi in the tires. Next tank was tracking equally well but made it home with still a half tank to go, and already over 300 miles driven on that tank.

I may never do it again, but I did it once.

600 Miles on 1 tank????

603 miles for 1 tank at 13.6 MPG?
You have a 40+ Gallon fuel tank?

Yes, the CCLBs have a 48 gal fuel tank. It's probably my favorite feature of the truck.

And how many miles do you put on a year? Some of us who clock substantially more than 10k a year, but need to balance periodic towing/hauling heavier than a half ton will allow, but daily drive, DO find reason to watch mpg. The difference in mpg between the lowly 6.2L and the premium 7.3L $1700 upcharge mill means upwards of $1,500 to $2,000 a year in fuel alone for me. Anyone who says mpg and heavy duty shouldn’t be used in the same sentence can write me a check for $10,000 right now.

Are you saying the 7.3 is more or less efficient than the 6.2? I can tell you from experience with the 6.2 the 3.73 gears are a lot more efficient than the 4.30. It was 10% for me going from 3.73 CCSB to 4.30 CCLB.

I am sure Ford fleet customers care a lot about mileage too.

One idea I am toying with is getting an F150 with the heavy payload package as a sort of baby super duty. It should get mileage in the high teens and still have over 2000 lbs of payload.

I would have to respectfully disagree. This coming from someone who had a 6.2 3.73 stock tire truck, and went to 4.88's w/ 37's. I lost less than 1 mpg on my daily average. My dad also has a 6.2 4.30 truck that I've logged a lot of miles in. There is very little difference in the fuel economy. And maybe that's because there's lots of hills here and possibly flat where you live?

I just went past the 3 year mark last month. Don't drive much (6k) but I do still keep an eye on my mileage. So far still keeping up with each fill-up and logging every one into Fuelly. At 25 fill-ups the lifetime average is 13.6 mpg with the best being 14.4 mpg - all hand calculated. The guess-O-meter has been optimistic 92% of the time averaging about 2 mpg more than reality - with only two times (8%) being spot on.

With a fairly even mix of town and highway driving, here is my hand calculated MPGs (FillUp app). My IPC shows a lifetime average of 15.6 and max individual trip, ~800 miles, of 18.2. Both are 5% optimistic over the hand calculated numbers. This truck with 4.30s actually has a better lifetime MPG average than my almost identically equipped 3.73 truck. (See signature). Admittedly, I don’t tow but do haul on occassion.

It is relatively flat here and either truck would pull 6th gear all day long on the highway as long as a travel trailer was not attached. With the trailer the 4.30 truck would run a gear higher than the 3.73, and that was pretty much the only difference there. Either truck could spin the rear tires in first with the trailer attached.

I was saying the 7.3L gets worse mileage. I, too, have considered going to a HDPP F-150, but I don’t like stripped trucks. The 2021 changes that... a bit, but regardless, if the trailer is pushing 8k, I don’t care to pull it with a 1/2 ton. That’s me. I’ve pulled a lot of trailers in 25+ years, and most with Super Duties. I’m just not interest in a $10k diesel adder when I’m trading every 3-ish years.

A question that begs to be asked is did you change your truck with forscan or at the dealer to account for the different gears or tire size? And the post that you replied to was comparing factory options, not re-geared trucks with larger tires. In the pursuit of fairness, that has to be considered.
