What kinda highway MPG's you getting with your full sized rig?

[duneyeti9]

Don't know if it will help you comparison wise, but I got a 6.7 powerstroke F350 and it gets 20mpg empty and 13-14 with a loaded Lance 835 (depending on the wind). I drive fast and pass a lot, just cause I can, BTW the mileage computer is within .5mpg of hand calculated every time I've checked it so I don't bother to check it anymore. Only got 10,000 miles on the truck so it's still kinda tight, might improve as it gets broke in.

I avg 14-16 hwy at normal speeds (70-75)

9-11mpg on my 04 F250 with 5.4L

2007 Chevy Crew cab 4.8 Ltr with a camper shell on back, storage unti in bed. I get 21 - 23 on highway depending on if I get a headwind or a tail wind. In town I get 15.6 - 16.7 MPG depending on how hard I have to drive to pass some of these bad drivers in town to get around and away from them. Towing a 3800 pound popup with two people and two Hobie Adventure kayaks on the roof of my truck and all our gear....about 15.8 MPG.....I've gotten as bad as 11MPG with a 40 PMH headwind...bad and scary trip for sure.

In my 1994 suburban (350 tbi and 4L60E tranny, 3.73 gears on 265/75/16 tires) I average 13 mpg running 70-75 mph. Around town and on short highway runs I will see an average of 10 mpg. Granted the last time I figured these nbumbers I had an O2 sensor going out and I have a bad IAC, but I am hoping to start getting a little better mpg with the recent tune up, new O2 and IAC.

2002 Tahoe, I'm averaging about 14 city 18 hwy. So I can't complain too much.

 

[Magnum Johnson]

Cant say much yet because my truck is still pretty new to me but I see about 21 hwy unloaded and 12-13 in town. Hope to get some more MPG's with some smaller tires.

 

[redthies]

Just a thought here, but all you guys who are responding without telling us what year, make, model and mods you have... Why bother? It means nothing without that info!

 

[Magnum Johnson]

Signature is not showing up I guess....

nevermind...worked that time.

Oh goodness someone is moody (red) lol 2002 Chevrolet Tahoe LT, ventshades, bug deflector, ranch hand bull nose front bumper, roof rack, stock wheels with 265 A/T tires. 5.3L engine with cold air intake and custome exhaust. I don't think the other mods would effect the gas mileage lol Is there enough info???

15 - 17 in my Ford 6.0, stock lift and 32's. But then I don't do any heavy hauling. Off road driving doesn't seem to hurt the average a bit.

That sounds like that 6.7L is capable of the MPG Ford was claiming it would get. Nice.

 

[DGarman]

'79 Ford Bronco with a carbureted 400, Np435 trans (non-OD), 4.56 gears, and 35-12.50-15 BFG ATs.

9 to 9.5 mpg all-around (10 to 10.5 mpg if it's level highway).

I hauled a car trailer with a '46 Mercury on it (5500# total) from Washington to SoCal (1100 miles) and it only (!?!) dropped to 8 mpg.

With the gearing and no overdrive it runs about 2900 rpm at 65 mph, so that's about the fastest I hold it at.

My 90 Dodge W250 with lots of go fast mods and 4" lift gets about 16-18 mixed driving, On the highway cruising 70 it gets about 18-19 if I slow it down to 60-65 it gets 21. I hauled a 93 W350 ex cab dually back from Western South Dakota and it got 10.5-11 going 70 through the hills that was weighing in at about 21,000 total and on winter blend fuel

My 93 ext cab dually 4x4 gets 18 - 21 on a consistent basis on winter blend fuel, It wouldnt surprise me if it jumped up a few MPG's this summer. usual wet weight on it is about 7500lbs. I havn't had a chance to check mileage on it with a good load.

That's what my wife keeps saying too... I must not have had enough coffee. I just figure we oughta know what is getting the good, bad, and ugly mileage!

My 99 Dodge 1500 reg cab with 5.9 gasser and auto with 285/75-17s gets 10-13 depending on how hard I push on the pedal. It is know someone else's guzzler. I will introduce the new rig (along with mileage info from the trip home) some time early next week!
