Ford 7.3 godzilla

[brancher147]

I have a 24 F350 with about 20k miles. I tow a good bit. The 10 speed transmission tows very well through the mountains. Much better than my old 13 F350. The 10 speed transmission does shift very rough sometimes but no issues so far. Gas mileage with the 10 speed is just as bad my old 2013. I average about 12 mpg without towing and 4 or 5 mpg towing 12,000 lbs or so.

Got a ‘22 F-250 7.3L first of ‘25 w/ 50k mi. Put 16K on it by now. Really like it. A lot more than the LLY I used before it. It would go between that LLY and the LBZ with a Kennedy tow tune. Loaded with Deere 310SJ backhoe with gooseneck on rolling prairie gravel roads I can get 35 uphill to easy 55. Had a serious headwind and got 55 on highway otherwise 70 mph easily.

I have a 20 F250 with a 7.3 with 105,000 on it. I love the motor and not having diesel problems. But I did grenade the transmission at 75k.

One upgrade I would suggest to address that little bit of lag is the petalmonster from Banks.

I've got 70,000 now on mine. It was shifting a bit rough so had dealer change tranny fluid at 50,000. Smoothed right out. Going to do that now at 45-50 to try and save the tranny as long as I can. Love the engine and truck though. Would probably pop for a nice non factory tranny if this one goes out at some point.

For 2027 Ford is making it the standard and only gas engine available in Super Duty, no more 6.8

They also gave it a little more horse power if I remember correctly

Geez that 6.8 only lasted about 2 years or so. Cost cutting at Ford apparently.

They ended the standard output 6.7, too, but the good news is that a Carhartt package will be introduced

My 21 welding service truck (7.3) averaged 3-4 at best, that keeps me away from gassers. Weird thing with that one was you could always smell hot oil but no leaks?

How heavy was that? Seems odd. Only time I have gotten 4mpg was towing a camper (aerodynamic brick) into a really strong headwind. The engine will smell hot (but temps read normal) after descending long passes in the mountains, the high rpm of engine braking likely is throwing a heat load into the oil I assume.

My 4x4 with 3.73 rear, 44” tires and the tremor valance/running boards (worse aerodynamic but more clearance) gets ~16 highway, 10-12 around town, towing a camper can range from 4-10 depending on conditions but 7ish is pretty common.
