I am wondering for those that have a 6.2 powered Superduty what is your MPG?
I ask you to also tell me what is your GVWR?
What is the Rear Axle Gear Ratio?

According to Ford if the GVWR is under 10,000 lbs the Horsepower is 385@5500RPM and Torque is 405@4500RPM.

While the GVWR'd vehicles over 10,000 lbs is Horsepower 316 @4179RPM and Torque 397@4179RPM.

I'm curious if there is a MPG difference between the different power ratings?

 

If I'm not mistaken the truck's don't make different power, they are just rated at different rpm's. But, my truck usually sit's at around 7,000 lb's with 3.73's 4x4 11.7 mostly city 13.5 highway under 60 mph.

 

My 06 sits about 7000 as well, and has 4:11 gears and gets 12.5 all the time. I stay under 2000 rpms on the freeway. Thats roughly 70mph..

I have steel rims and stock BFG's with nitrogen. at 70 psi.

When I tow may race trailer I get 10.5 and 12 flat towing my airstream.

I have a 5.4 with torqueshift trans. I have no mods other then Ford Motorsport tune from the dealer.

I just through out my.02 for comparrisons purpose

 

I have a 2012 F350 Reg Cab 4x4 with 3.73 gears and getting 12mpg around town. I don't use the highway much but I do wonder what my MPG's would be. Usually I cruise at 40mph and in 6th gear thats about 1,000-1,250rpm's.

Although I wish I was getting a few more MPG's I understand why I'm getting why I'm getting. One thing to mention, mpg's didn't change when I was carrying my plow or towing my 6x10 enclosed landscaping trailer with a Walker mower and plenty of tools.

For what it is, I think the thing is pretty sweet.
(Even if I have snake eye in my brand new paint)

 

Moved to the 6.2L V8 forum.

 

What azgard said is correct, same exact motor and hp/tq, just rated at different RPM's for the gub'ment.

My numbers:
MPG's - 10mpg city/~14hwy (rarely on the hwy though)
GVWR - 11,200
Gears - 4.30's

I saw your thread about the paint, hope Ford takes care of you.

 

I have the 10k GVWR (ordered it that way because of annual registration and inspection costs in this lovely state that I live in)

3.73 and I'm getting about 16 highway (70 mph) and 12 city.
There is a definite improvement in MPG's over my 5.4, which surprises me especially since the engine is breaking in.

 

2011 f250sd sc,long bed 4x4,9600 gvwr,3.73 gear around town on gas 10.5 mpg,on e85 7-8 mpg

 

Wow! Those E85 number's are horrendous. That's a 24%-33% reduction in gas mileage. How much does the E85 cost relative to gas?

 

I think E85 is more expensive now around here in the Detroit area. But before was only about 20-30 cents cheaper.

I am getting about 11 city and 14 highway. Truck weighs in at 7200 with full fuel, 3.73 gear, crew cab.

 

I have a 2012 F250 Superduty 4x4 Lariat, with the 6.2 liter gas engine, it also has the 10,000 GVWR (Not sure what that does to help me) it has the 3.73 electric locking rear end.

When I looked up the specs it said the motor had 385 HP and 405 ft/lb of torque.

No where did I se it was lower because of the 10,000 GVWR option.

How can I determine what the HP and torque is for my truck?

Without having it put on a dyno.

I just found this.

http://www.ford.com/trucks/superduty/specifications/

What is the point of less hp and torque on a truck with a higher GVWR?

Can the motor be tuned to get to 385/405 or more?

 

ethanol has less energy than gasoline, that is while the mileage is terrible.

I wouldn't run E85 through anything even if it was half the cost of gasoline, it makes good starter fluid for a campfire.

 

To SNELLDOG & anyone else in the lovely state of Ma.

I had no idea that I was going to have to register my plates every year at a cost of $20 per thousand lbs. Now heres my problem with the system. I just bought a 2012 F350 reg cab.

My plates from my trade in were good untill 2012, the new commercial plates I just got in the middle of December 2011 need to be renewed at the end of the month.

I'll have paid for three sets of plates in under a year, my new commercial plates...$240 a wack and I only have a reg cab but have to register it at 12,000lbs because of the 11,300lb tag on the door. Man did I really screw myself on this one!!!!!

If I had known better I would have gone with a F250 like SNELLDOG and I could have avoided this and having to abide by our lovely DOT laws. Fire extinguisher, Reflective Orange Triangle and wheel chucks are manditory at all times with yearly inspections, oh and plate renewal fees...

I feel like an 18wheeler driver with all the hoops I have to jump through.

Still love the truck!

 

That's why I ordered up with the 10k package. And it's a 350, if that matters.
Saves me a couple hundred a year, the wife always laughs about how I'm saving the family money with my new truck, LOL

 

Read the thread in its entirety, same hp/tq between the trucks but taken at different rpms (epa)...
