MPG Report - Road Trip

[forddude343]

Just hit the road for a 400 mile trip.
Hand calculated 17.8 MPG highway moving mostly at 75MPH, with perhaps 10 miles of stop and go driving. Calculated both to and from separately.
This is a 2010 F350, 6.4, SRW LB FX4 XLT, with 3.55 gears.
Truck is 100% stock, folks.
Tow a 20' RV on a regular basis, and the truck doesn't even feel it.
This is for those who feel the need to jump to a newer rig for MPG purposes.
Just trying to help cut through the BS regarding the MPGs of this drive train.

I'm glad I thought I was going to have to change to a 3.55 rear end.

Sy1616, I have the same truck as well, and I'm seeing the same numbers as Ford Dude. You must be a 6.7 fan boy. Go back to driving your overpriced, overhyped, underpowered POS.

I'm not a fan of the 6.7 but my truck stock only got 15 at best. My truck now will get 17 and 18 mpg on the hwy but not stock. I see you have 1 post so before you keep insulting people I would think if I might need some advice in the future.

the dudes numbers might have worked out just like he said [17.8 @75mph],but unless he was diligent and spent the last 5 minutes on his fill adding the last 4 gals bringing fuel right to the brim,his numbers will not be accurate.also flatlanders will show much better than hill country people.i'm hill country with a 3:55,cant make 14mpg driving like a granny ...when you look like ernest borgnine and and a pretty gal says to you.... "you are the handsomest dude ever"...you walk away smiling and happy

Well, I'm in swamp country, and I sure don't ever see nearly 18mpg at 75mph. Not even on my Lie-O-Meter unless it's down a slope. I might be able to pull almost 17 at 70mph (driving like a granny on I-95), but 75? Nope.

And I still get a chuckle out of those who tow something and say "the truck doesn't even feel it", "the truck doesn't even know it." Yeah right. I have a 8000lb travel trailer and I can just look at the boost gauge and go "Yep, there's a trailer back there."

I agree, he's likely adding the 3-4 galons then dividing....common mistake, i made it too.
