Looking at buying a 6.2 very soon, using it during the week for a lot of unloaded highway driving. Any input on using the 6.2 in this form? Maybe a few hundred pounds in the bed, but not much of a trailer load with these highway miles.

I can't justify the Power Stroke just for extra MPG, and I'd assume the suggestion would be to get 3.73s on my 6.2?

 

I have the 3.73 and would only advise them for regular unloaded interstate/hwy driving(60mph+). If larger tires or towing is in the forecast I would strongly recommend 4.30. I think the best possible mpg in the F250 is had with the stock 245 tires or something in the range of a 31.5-32" tire. I have 33" now and since my switch from the stock 31.5" I feel my unloaded hwy mpg has suffered some. I can hit 14-15 mpg for only hwy miles, once I hit traffic or town my instant gauge eventually evens out around 11.
One of my reasons for wanting to order a new truck already is to get the 4.30's.
I have owned a lot of Powerstrokes, IMO, the only justification for owning a new one anymore is for regular towing or towing in excess of 15k.

 

I have 3.73's ccsb 4x4 and the tiny 31's. 12 mpg is all I have been able to manage, and I have been babying it. If I run 70 with the cruise on, it's actually under 12. I'm really hoping it gets better with some miles, currently at 2,700. I switched brands of gas today, going to see if that has any effect on this tank. FWW, my lie-o-meter has been very close to pencil and paper, within .1.

Oh, first couple tanks were under 11, found my hubs had been left locked in from the dealer.

Edit: I should mention that my daily commute to work is only 9 miles, with lots of red lights, most I miss in the am, but most I hit in the pm. I have been on several long highway trips.

 

Are you still on winter fuel? My XL off the lot was an easy 14 on the hwy with the 31.5 stockers.
My daily one way commute is 15 miles. roughly 7 hwy and 8 town. I finally got 11.2 on an entire tank fill today. It has always been under 11. I have 6k on my truck now but the fuel is no longer winter blend and that has helped.
I will be curious if your dads new truck does better.
12 mpg for pretty much town driving is great IMO. I can reset the mpg meter on the hwy and have it say 14-15 for the first part of my drive and then by the time I get through town I'm back around 11.

 

We have been back to summer blend a little over a month now. I have a 600 mile one way trip planned in early June pulling my 6k dry 30' travel trailer, loaded down and a golf cart in the bed to the outer banks of NC. Very interested to see what my mileage will be on that trip.

Your geographical location plays a huge part in mileage. Here in The foothills of East Tennessee, I'm never going to see the mileage that someone in the Midwest or Florida is going to see.

And I guess 12 city isn't to bad, but what gets me is at 70 on the interstate it's below that, I would expect 13-14. If I had long enough stretches of highway that I could run 55 for a long distance, I'm sure I could get 15+, but I never drive those long stretches of highway.
I went with 3:73 thinking if I really babied this truck I could average 14 like some others have, if I had known I was going to average 12, I most definitely would have waited for 4:30's. But like I said, maybe it will get a little better with some miles.

 

My baby is a 2012 standard cab with the 3.73's.

Currently have just over 48,000 miles. I have gotten over 15 mpg on the highway at 55 mph.

It tows fine, made several trips back and forth between NJ and Florida. with a 8.5x20 loaded trailer, right at 10,000 pounds each time. I stayed at 55 mpg when towing heavy and got 13 MPG

Currently I have a 15 mile commute each way - a couple of times a day, about 3 miles of it is in town traffic, couple of traffic lights etc, the other 12 miles is a nice stretch of country roads, occasionally stopping for a school buss or a turning vehicle. I have the manual four wheel drive and keep the front hubs locked in as I go a few hundred feet off road in the Florida sugar sand each trip.

In the winter months when I prefer open windows to air conditioning I stay right at 15 mpg. As soon as I start to regularly use the AC the mpg drops to 14 mpg.

I would describe myself as a conservative driver and do notice that if I let my darling dearest son drive the truck, the MPG will go down about 1.5 MPG as he is not as conservative a driver as I am.

Bottom line - great truck and I have had no issues with the 6.2 - 3.73 combination at all.

 

I will be heading to Outer Banks at the end of June. It is about 700 miles one way for me. Good luck on your trip.

 

Thanks, good luck on your as well. This will be our first long distance trip, and first time camping at the beach.

 

to the OP,

I average 14-15 around the area... Empty. mine is 2 wheel drive..

and last winter... on 1 trip.. 150 out and another returning ...
I got 19.. (Real ) but this was side roads all the way.. so 50ish... flat land and little wind. South Carolina.

 

Good info. Thanks Chuck

 

Wow, 19 is great. You say 14-15 around the area. I'm averaging 12, I would attribute 1 mpg to 2wd vs 4wd and the rest to your flat land vs my hills.

 

true.. less drive parts, less weight... and more miles...


142,800 miles currently.. but runs great.

I lost about 1 mpg when I went to new wheels and 35's. Just got back from a 700 mile road trip and my avg was 13.2 @ 70mph mind you i'm in Florida where is all flat. Towing my travel trailer 33ft Forest River vivbe loaded 8400lbs im doing about 7.8-8.4 mpg.. My boat Sea Vee 32 ft 10,000 lbs im doing 7 mpg. I also have 3.73 gears on my 6.2. I had a 6.7 and it was only about 2 to 3 mpg diffrence. On road it would do 15-16 empty maybe 17 under 70.

 

This is what I'm hoping for. Just ordered a 2017 with the 6.2 and 3.73's

 

I average around 14-16 if I go 60 with 265/75/17 tires. 70 mph is closer to 14 ish.
80 12.5 or 13
