Fuel Mileage?

[Schnot]

What kind of fuel mileage you guys getting? Ill be in the market for a new Hot Shot truck later this year but I wont get away from my 7.3's if there is no mileage with these new motors.

Id rather just spend 10k on a new motor and all the fancy mods and get over 12 loaded down than spend 60k on a warrantied truck and get less than ten when loaded.

I want realistic numbers so dont inflate them just because you love the truck

I haven't driven a full tank loaded down yet but I got 13+ on mixture of pulling then back to city driving. My brother may be looking to replace a 7.3 in a couple months so let me know if you find a good deal. He only has 380k, wish they would last.

On side note I am over 7700 miles now and last tank I got 16.5 mpg. I still have not driven a full tank just highway miles but I am seeing the mpg's improve. (and I am not hammering on it as much either.)

Hell yeah! I love my 7.3's! We've had them all the way since 94 before they even put the powerstroke logo on it. We've have five now and not one has any less than 250k and the highest is 425k. And they all run like a top.

Ive heard some great things about these 6.7s and all the power that they have. And to be honest I would really like to be driving around the country in a nice new truck and not one that the seats are litterally wearing out in. Hopefully these will be worth it.

Unloaded I get 13.5 - 14.5 hand calculated. My speedo is 2 mph off. Completely stock i was averaging about the same. I have not ran enough fully loaded to tell anything. I ran about a half a tank pulling about 12k and that tank still averaged 13.3.

14.5 hand calculated on highway over the past 6000 miles. I ran a full tank through her the other day hauling calves. combined weight of 16,000 pounds, no wind and got a wopping 9.8 :/

No matter how I drive average is 16 mpg + per tank with a 350 long box 4x4 dually. The 6.7 is a awesome power plant, but I have owned (2) 7.3's and can tell you the difference in the handling is far superior on the new trucks. They are effortless to drive > handle like a sports car and the turning radius is unbelievable. Spent a lot of money but Love everything about it. Have no regrets...

F250 Crew with 331 gears 5800 miles and I consistently get 17 miles per gallon(hand figured) on the road and almost the same in a combination of town and rural driving.

pick your mileage... play, have some fun...and around town I see 14.5-15.5 hand calculated. Back out of it, no quick take offs, drive like a geriatric flatulent... get around 18-19 around town. Cruise highways at 60, rolling easy.. I have seen 22-23. Pullling 15k, not rolling easy, foothills...9-12 mpg. You can pick your mileage by adjusting your driving.

I'm seeing 16-18.5 unloaded driving between 8500' and 5500' elevation, mix of highway & in-town driving. Currently 5200 miles on the odo. 3.55 electronic locking rear.

I did a trip to sea level, towing a 20'x8.5'x8.5' enclosed trailer, 15,000 lbs gross, 82mph highway, 10-15 mph cross wind - got 9.6 mpg. Coming back on a leg gradually going from sea level to 4500' elevation, with 20-30 mph headwind, 75-82 mph depending on the winds, I got 8.5 mpg. No lack of power issues.

Dealer Service Manager tells me I should expect that number to get up to the 12-14 mpg range towing once I hit 15-20k miles on the motor, based on the fleet trucks they service, so we'll see.

'01 7.3 got similar towing mileage in summertime with 3.73's. Winter mileage typically 2 mpg less. Empty mileage this winter (direct comparison to current 6.7 mpg conditions) was 12.5-13.5 on same roads, so 4-5 mpg lower. MPG's went up on 7.3L at 70k miles. Best summer combo driving empty on same roads I now drive the 6.7 was 15.5-16. Have not had 6.7 on summer fuel yet.

I have around 7500 miles and this link will show you a few more details of my mpg:

Super Duty (Ford F-250 Super Duty) | Fuelly

I have had only 1 tank out of 21 towing. Most miles are driving around the Houston area. I drive posted speed limits or just a little below. I have found that wind direction and speed effect the mpg more than anything.
