Truck Fuel MPG

[KG406]

With a mix of everything from interstate to two tracks and mountain roads this is roughly what I get. I don't track MPG when towing... am happier not knowing.
'08 Tacoma, 4.0L, 265/75R16 C rated Duratracs - 16 mpg
'11 Chevy 3/4 ton, 6.0L gas, stock sized E Wildpeaks - 13 mpg
'19 Chevy Colorado (company truck), 3.6L, stock sized SL hwy tires - 20 mpg

Some of my more recent previous trucks, all had E rated AT tires slightly larger than stock size:
'15 Ram 3/4 ton, 6.4L gas - 12 mpg
'14 Ram 1 ton, 6.7L cummins - 16 mpg
'06 Ram 3/4 ton, 5.9L cummins - 18 mpg
'96 Ram 3/4 ton, 5.9L cummins - 18 mpg

I'm actually least happy with the mileage of the Tacoma just because with a tiny 21 gallon tank the range is pretty limited so am usually hauling extra fuel jugs when I head for the hills.

1997 Dodge 1500 Ram 4x4. Lifted/4.10 gears/33 inch tires-5.9 liter gas engine.
Highway mileage when empty usually 12-13mpg. 70 mph tops
Highway mileage when towing my TT about 8mpg on a good day. Never over 65 mph

2017 Ram 2500 4x4. Stock size 275/70/18 tires. 3.42 gears. 6.7 liter diesel
Highway mileage when empty usually 20-21 mpg. 70-75 mph
Highway mileage when towing the same TT loaded quite a bit heavier 14-16 mpg. 65-70mph.
The best part about my new truck is that it does not slow down, no matter how long a climb we're going up and that's in 5th gear overdrive.

2019 4Runner with Durotrack off-road tires. Get about 16mpg average. Likely the worst fuel economy to power ratio of any modern rig on the market :-(. Does great off-road though.

07 Dodge ram 2500, 5.9 cummins. Actual 18-20 with the lie o meter showing 24. I drive pretty slow, no rolling coal, and only 70-72 on the HWY as the mileage drops off fast past 72. I have a chip for mileage (not for more power), and exhaust mods to let her breathe a bit.

My 04 got more like 20-22 as the motors in those had a bit less power, and it was an ST which weights about 1,000+ pounds less than a mega cab laramie with lots of tools in the back.

My 11 with the 6.7 only got about 12-13 so I sold it within 6 months and went back to the 07.

2017 F250 6.7 Powerstroke. 3.73 rear end stock size tires. 80mph on the highway empty 16 - 17mpg. Pulling small 16’ trailer +- 5000 lbs @ 75mph about 12mpg; 35’ gooseneck loaded down up to 16k lbs as little as 7.5 mpg.

Gas or diesel? I had a 2006 2500 HD that was probably one of the best work vehicles I've had. It had 4.10 gears as I recall, and the Vortec 6.0. I don't know that I ever broke 14 mpg with it. It would go anywhere though, especially with chains on all corners.

I still have my 2001 2500hd with the 6.0 and use it solely as a ranch/hunting vehicle. Fantastic truck and I can vouch for your statement that it would go anywhere chained up on all 4, but I know it never once got over 14mpg even downhill with a tailwind!

2018 F-150. 4x4. V-8. 6” lift. 35 in. AT KO2. At low altitude no load average 15-16. Make it out West and pick some altitude increases to 16-18. Efficiency really drops off above 70 mph.

Wow. Regional price disparities like this make no sense to me.

Guess I should've ordered them from out of state! I'd prefer the duratracs just because I know they work really well, so far the at3s are holding their own tho!

I’m sure the Toyos will serve you well. They’re severe snow rated and a good looking tread pattern. Don’t look quite as aggressive as DTs.

For a 275/70R18 load range E, GY was $240 per tire after factory rebate and Toyo was $276 per tire.

Ford F-150 3.5 eco boost. All standard parts and gears. Gets about an average of 20 miles per gallon.

 

[JLS]

Tundra, 4.30 gears, 5.7V8, 2.5” lift, +1 sized Goodyear Duratracs, topper

14-15 freeway
15-16 highway
9-10 towing 7k TT @ 65

Headwinds suck.

 

[mdhunter]

2018 F-150 eco boost, 2” level kit, AT tires, 16mpg

2021 GMC 2500, Duramax, only had it for a 1,000 miles but its averaging 18.5

 

[Mallardsx2]

Ram 2500 6.7 Diesel 2016

Highway 20-21 MPG
Regular driving 16-19 MPG
Towing pretty much anything -12-15 MPG

 

[swoleymammoth]

2018 Silverado 1500 Z71 crew cab short bed with 5.3L engine. Only mods are removed lower air dam, 275/65r18 P rated Nitto Terra Grappler G2s and a soft tonneau cover. Over 45K miles my average is sitting at 19.7 mpg. Not bad for a 1/2 ton truck! My previous truck, a 2004 Dodge Ram 1500 5.7L with a leveling kit and E rated tires got 12-13mpg.

I have a 2020 GMC Sierra 1/2 ton with the 6.2liter engine. We drive back and forth between Fargo and Bozeman several times each year. I have gotten as much as 20 mpg but that was driving probably 65 because of road conditions. My wife typically drives 80 - 85 mph & then we get around 17 mpg. Really like this truck except for the auto stop. I especially like the new tailgate.

I have same vehicle in AT4 package and duratracs and get about 1 mpg less.

 

[Brandon270]

2005 silverado single cab 4wd with 31" all-terrains, leveled. 5.3l with 3.42 rear end. I have a cold air intake and a custom tune running 91 octane. My average is 16.5 I can get as high as 20-21 on the highway with no trailer or load.

It's getting close to 200k miles only parts needing replacement are ball joints and a water pump. I'll keep it for work when I get a crew cab truck eventually. It's hard to put a car seat in a single cab truck.

'18 2500HD GMC...around 19mpg optimum highway with Michelin LTX AT2 275/65/R20...switched to TOYO Open Country 295/65/R20's & took about a 12% fuel efficiency hit.

*trailer hit is about 40%

1999 f350 7.3; 15.5

2020 f150 3.5 eco; 17.5

I have two K3500 Duramax trucks, an 05 and a 17. Empty on the highway, both get 20+mpg at 70ishmph. The 17 does a little better than the 05. Everything is stock on both trucks with 3.73 gears

Towing a horse trailer with two or three horses inside with a slide in camper in the bed,, without a headwind 13ish, headwind 11ish,,,and on the very rare occasion when you get a tailwind 15ish. That is setting the cruise at 67 at just going down the road.

My Camry got 21 mpg pulling my 6 ft trailer to and from Wyoming last year. Close to 30 without the trailer.
