3/4 ton Ford vs GMC gas mileage

[MuleyFever]

I am considering a 2022 GMC or Ford 3/4 ton with a gas motor. Just the standard v8's not the larger options. I dont remember the displacement off the top of my head. Does anyone have real word mileage on these two current generation trucks/engines? I am wondering if there is any significant difference.

I have a 22 f250 with the 7.3L w/3.55’s it’s a S crew short box. It’s got 7300 miles. I’ve checked every tank so far and my average is 12.7mpg. That’s 1 mpg better than my 2018 6.2 got in 62,000 mile average.

2022 chevy 2500 crew cab standard box 4x4 6.6 gas 14 mpg average. Best 50 mile is 19.5

I have a 19' f250 crew cab short bed 4x4 6.2L, run around with about 800lbs of gear in the bed. I average around 12.5 mpg. The new trucks have the 10 speed transmission over my 6 speed, so the mileage might improve. Also I have put 195k on that powertrain with no problems.

I had a 2020 F250 gasser rental I took from western Colorado to Arkansas and back towing a 5,000 boat and averaged 9mpg. I believe it was the smallest gas they offered in that size though

My 2019 F250 CC 4x4 with a 6.2 and 6 speed averages 13.5 gallon empty.

2022 F350, 7.3 engine. 4x4 supercrew door short box, 4.30 gears, averages 12.4. keep it around 55-60mph it’ll get over 13. I like the way it sounds, so drive like a kid sometimes.

towing 10k, it’ll get 9. That’s all the heavier Ive gone with it..

What is the 7.3 like? that's a monster of a motor.

It’s impressive, this motor with the 10 speed is incredible. I haven’t driven a 6.2 with the 10 speed to compare it to so I can’t say if it’s the motor or transmission.

I have a 2019 F-250 with the 6.2 motor and 3.73 axle. It's a crew cab, short bed, 4x4. My typical fuel economy is around 12 mpg mixed city and freeway. Most of my driving is at around 5,000 ft. of elevation with 85 Octane.

I test drove a Chevy before purchasing this and I liked the ride on the Chevy better but it just didn't have the power I wanted. I'm sure that also translates to better fuel economy if that's a top priority for you. Pros and cons to everything. I currently have another Ford F-250 on order with the bigger 7.3 gas motor and 4.30 Axle ratio as I was tired of slowing down so much on the hills while pulling my toy hauler.

I’m thinking about ordering this exact setup. How does it tow?

It tows great, just like a big gasser should, but it wont pass many gas stations even with a 34 gallon (i think) tank. I have a load of hay to haul this weekend for a friend that'll be 14,000 lbs ish, but I'm not concerned about it at all.

The ten speed makes it nice and it really only drops down low in the gears on long hills (down to 7/8 usually), but the torque curve is different than a diesel. granted I've never had it in the mountains and likely never will with a load on it. We have a duramax in the garage too (wifes truck) if we ever do that

'21 F250 7.3, 4.30 gears, Tremor package so it's got a lift and 35s, super crew/short box...In eco I get 13.5 around town and almost 17 on highway. Running 80/85 empty is goes down to 15.5- 16ish...I do have the pressure down on my tires..cause 80#s in the rear empty is a little hard on the seat.

My work truck, 2020 f250 6.2 crew lb 4x4 gets 7-8 in town 11-12 on the road. Truck has about 200# of load on average.

I'd you end up getting the Ford, it's worth the slight upcharge for the 7.3 engine, which will also get you the 10 speed auto. The 6.2 v8 in the F250 comes with the 6 speed auto. Mileage between the two will be close enough to not matter, with a slight edge to the 7.3/10 speed.

I had a 2019 F250 with the 6.2, avg mpg was 11.9.

Depending on what your towing i would look into the 3.0L LM2 Diesel in a chevy or GMC 1500. The 22 model has a towing capacity of 13,300 and unloaded on the highway they will get an amazing 30+ mpg.

 

[Fatcamp]

Surprised about how many Fords there are around here.

2017, 6.2, 6 speed. 9 loaded, 14-15 open road.

I would tend to agree, the mileage on the little duramax is attractive, however, the payload on these half ton diesels is very low, and to get to the max 13k towing, you're adding a package, and may have to give up some capability (4x4 even?, I'm not a dealer or sales person, but have looked at them). if you're towing around 10K (with the max package) you'd be close to or over the payload.

Coworker has a higher trim 2021 GMC with 3.0L duramax in it, and payload is only 1,350 lbs or so, per the sticker on the door. That compares to our 2500 Silverado duramax with payload of over 2800 lbs (still not great for a 3/4 ton, but its a 4x4 LTZ) and my F350 7.3L with payload over 4100 lbs (has camper package and higher GVW).
