Real world fuel mileage

[cacklercrazy]

Lets do a data base thread on what kind of fuel mileage you are getting in your truck.

Post your trucks year, motor and any mods with the fuel mileage...minimum commentary.

My 2012 Tundra with the 5.7L, Icon suspension that lifts it about 2" and 33" Toyo's is getting 13.6 all around [mostly city] and gets 15 on the highway averaging 75 mph.

F250 6.4 diesel ,stock size tires, it's programed,but don't know which one. Had a great mechanic work on it. I get 18 to 19 in town. Freeway up to 26.

2017 Ford F-150 4x4 w/ 3.5L Ecoboost
2" Front Leveling Kit
33" Falken AT3W's
19mpg highway with cruise control at 75mph
16-ish around town

2008 GMC 2500 HD, 179K, 20MPG on highway @ 70 MPH.

 

[2rsquared]

2005 GMC Yukon XL 1500

5.3 liter
3.73 axle ratio
2 wheel drive
225,000 miles
Original owner
Michelin LTX M/S (@40 psi)
Bone stock

Cruise set at 5 over (~75 mph)

Best = 21.6 mpg ...AL to PA unloaded with 10-15mph Southerly tailwind.

Worst = 15ish mpg ... Houston to Del Rio fully loaded (not towing anything) for a hunt into strong headwind.

Longest round trip = 19.6 mpg ...PA to ID to PA. Loaded up for Elk hunt. Mpg was better coming back East than heading out West (Rockies are taller than the Appalachians). Winds mostly out of the West/NW. Was really digging the 80 mph speed limits out there and stayed at my +5 rule of thumb.

Average = 19 mpg cruising interstate.

This ^^^ is what the sticker said it should get and pretty much holds true.

As you can see...can vary quite a bit depending on headwind/tailwind and uphill or downhill.

2019 Nissan Frontier Pro-4x. Averaging 19mpg combined driving.

 

[Colterw]

2014 Tacoma 4.0 v6 crew cab with 6' bed
Roof rack and 31x10.5 tires

I rarely see better than 17 mpg. Most if my driving is 4wd on gravel roads though. I lost at least 1 mpg with the roof rack, I hate the noise it causes and it makes me look like an overlander but I really like the extra cargo capacity.

2015 Ram eco diesel, leveled ,33” tire full delete camper with roof rack , 27. Mpg average on highway.
2016 Tacoma stock tires 21if I’m lucky

 

[DudeBro]

2022 Ram 2500 4x4
Cummins
6'4" bed
Crew Cab

11000 miles (elk trip from VA to MT 6 days after buying)...average 19.3 mpg in and around Northern VA and DC

 

[lifeisgoodsteve]

2011 Chevy Duramax
Crew Cab Longbed
34" tires with no lift/level

15mpg mixed
17mpg highway
10mpg towing 25' about 9k lb trailer

Thought it'd have been better but this is the real numbers I get.

2017 GMC Sierra 1500. 4x4 (6.2l) - 2.5” lift and 34” BFG’s
16.0 mpg average over 93K miles

2006 Dodge Ram 2500 Mega Cab 4x4 (5.9l Cummins - stock
12.8 mpg average over 167K miles

These are hand calculated and tracked using the Mileage Keeper App (used a log book before that)

Hard to believe you are only getting 12.8 in the Ram, unless that average is mostly towing.

2020 tundra 5.7
stoclean everything

2015 f350 power stroke fully deleted 14 with the trailer 18 empty.
Lots of times fuel mileage is indicative of the driver not the truck….

 

[Forestryguy]

Has anyone kept track of all these milages? Just wondering what has come out as the best efficiency.

 

[widnert]

Love how no one that I can see even mentions the gear ratios when posting their numbers - as one of the primary influencers of fuel mileage this should be key in factoring efficiencies. For cars and SUVs, those are sort of irrelevant since you don't get to choose really, they're all built the same but for any pickups, this is something everyone should be considering at time of purchase. Just my suggestion to help balance the data being noted above.

For a lot of trucks, you can choose from something as high as 3.21:1 all they way down to 4.71:1 or 5:33:1. This makes a HUGE difference in fuel economy when everything else is the same (engine, trans, etc.).

 

[Sapcut]

1999 Toyota Land Cruiser with 455k miles, 33s heavy hitch rack, hunting gear…consistently gets 13.5-14.5 mixed driving on interstate and in woods every single day. I bought it nearly five years ago for $2800.

Buying practical vehicles based on getting better gas mileage is a very expensive myth.

My five other LX470/ Land Cruisers all get about the same mpg.

 

[Spoonman]

Newer truck for me.

2019 GMC AT4 6.2L
6” lift
36” tires
Flowmaster exhaust


14mpg on average.

 

[NateO 77]

2019 Tacoma 3.5L with manual transmission. 2.5" OME lift, 33x10.5 tires with a canopy. Highway around 65 I get 18.2 mpg. 72 to 75 I get about 17.5mpg.

 

[EastMT]

2014 GMC 2500hd 6.0 gasser. 14 mpg empty, 11 mpg towing 10,000 lb car hauler load.

I was going to trade it off for a better mpg truck like 19-20, but after doing the math, the low amount of miles I drive it, just not worth the cost diff vs gas savings vs towing capacity.
