Home Forums Gear Hunting Trucks and Four-Wheel Drives 7.3 Gas - How they holding up?

I noticed a few months back a few guys bought the Ford 7.3 gas. Been a good outfit?

There is a 7.3 thread a couple pages back you might check out. Mb

27,000 miles on my 2022 Lariat, running strong and not a single issue yet. First Ford so figured something would have gone wrong by now. But so far, so good.

15k on my 2022 Lariat and flawless thus far.

Thanks for replies. I would like to find a decent used one. Not an easy task.

I know they're HD pickups meant for towing, not MPG, but I've still got to ask:

Mileage running empty on the highway and @ what speed if you don't mind?

As high as 17 at 70. Hills and headwinds affect. Daily driving 13 with 50-50 California freeway driving.

I had to have a catalytic converter replaced at 20,000 miles, otherwise it has not been in the shop.
22 F250 XLT premium package, 28,000 miles.

22 f250 70-75 11 mpg......around town 10-11.......I was hoping for 15-16 on the open road. 16,000 miles.

had to have evap can filter cleaned because of intake location....sucking up dirt....bob

Interested to hear how the 6.2 and 6.8 do in the same vehicle config. mileage-wise. I don't pull that often but am thinking I may want to move up from an half ton for the mountains, and we have lots of them!

I have a neighbor who had a 2020 with the 7.3. He said 14 mpg for daily driving. If he ever had it on a road trip I'm not aware.

Just did first trip empty over to KS and back in a while. Had a 5-7 mph tailwind on way out. Doing 72-73 mph got 15.1 mpg. On return trip, calm winds, doing 77 mph the whole way, got 13.8 mpg.

Ordered mine with the 3.55 rear end as I don't tow huge amounts. Just upgraded to Bilstein 5100 shocks and ride quality is easily 2x better. Huge improvement for not a ton of money.

Still loving the 7.3 in my Tremor. Just a fun truck to drive!

Which gear ratios if you don't mind please.

4:30.....but it has a 10 speed so you would think that it would make up for it.....bob

Mine has 4:30 gears and I average around 12.5 MPG empty at 70-75.

I've got 33k on mine, has 4:30 gears and 37" tires. Lifetime towing MPG is right at 10, split about evey between a 4 place snowmobile trailer, and our 10k 5th wheel. Maybe 1/4 of those miles with the SxS trailer on the back of the 5th wheel (additional 3k).

The engine is very impressive, just this past week went and hauled a dump trailer with gravel (13k), the truck doesn't even care it's back there.

Now, the 10 speed transmission, that's a whole nother story.

So...whats the story? Some of us would like to know of any issues.

I went to several dealers looking at F250 , with the 7.3 used vehicles, from mid trucks all the way to most expensive, none had over 30-k, looked on steering wheel at current mileage from last owner, everyone ha 12 to 14 mpg recorded, don’t know what rear end or transmission they had, but decided I would keep my Ram that gets 18.5 mpg , not much difference between premium and diesel fuel prices.

Didn't some of the early 7.3 gas engines have some piston or rod issues?

Mine doesn’t require or get premium. Manual calls for 87.
