07 6.0 vs 08 V10 tow report

[mudfuel07]

Took a trip with my new to me 2007 F250 6.0 this weekend. Drove the same route that I had with the V10 many times. While the V10 did seem more stable, even with a lift, the 6.0 did well and it was windy. I definitely need to upgrade to the 08 tow mirrors, the 07 ones are dinky! The big thing, the main reason that I got a diesel, the mileage. All of this was hand calculated, so I know it's reasonably accurate. With the V10, I would get at best 4.5 mpg's towing the trailer. With the 6.0, I got an honest 10.5 mpg towing that included stop and start traffic and what we Floridians call hills. Broken down, it is cheaper for me to tow with the diesel and pay the slightly higher fuel cost. And please, don't bore me with all the 6.0 hate, I'm working on the known problems slowly but surely. Just wanted to give an honest report on the difference in mileage between the two engines.

My V10 sniffed 12 once, empty. 6.0 gets near that towing. Keep an eye on what's happening under the hood and make the recommended changes/upgrades and you'll have a reliable towing beast!

Your speedo was off cause of the tires, you really got a bit better mileage with the V10 than you think. 4.5 is pretty much the lowest figure I've ever heard of.
Not by much mind you :W
Enjoy the 6.0

Something wrong with getting 4.5mpg
8 towing, 11 not.

Enjoy the new truck OP... I will not beat up on you for choosing a diesel! While the 6.0 doesn't have the best reputation the rest of the truck is FANTASTIC. And the 6.0, when performing in top shape, is one of the most well mannered diesel I have ever driven.

At the least I would invest in a $200 ish ScanGauge II just to make sure the oil temps and the coolant temps are within 15 degrees of each other. Taking emotion out of the equation. If they ever go beyond 15-20 degrees in difference stop the truck and call a wrecker before you blow a head gasket. That means there is an oil cooler or EGR cooler or both failure and you NEED TO STOP IMMEDIATELY.

Monitor, Maintain, and enjoy your new to you 6.0.

Thanks!

Exact same numbers for me, wether pulling a 30' trailer or my former 41' weekend warrior (probably helped the WW had a nice curved front cap). And that includes Oregon hills. That can mean 7% climbs for miles.

There are no number of miles where the fuel economy savings on a 6.0 would ever pay for the upgrades required to make it acceptably reliable to me, once the extra fuel cost (around here) is factored in.

Gas is only about 20 cents cheaper than diesel here right now.

The truck was in top shape other than an exhaust leak, two broken studs. The numbers are right, I also mentioned that I was running 37" Toyo MT's. The best I ever got on the highway unloaded with the lift and tires was 9.5.

4.5 mpg towing something was wrong there! My V-10 gets 7 towing when i had the 285's with the 265 and a hwy tread i can get near 8.

My 99 v10 mh was 20000lbs and pulled my Chevy Colorado and got 6 to 7.

My V-10 has always provided better mileage loaded than that. It seems abnormally low

Were you lifted and running 37's? Before lift, I would average about 5.5-6 with a lighter trailer.

That is good to know. I've wondered what the difference was between the gasser and diesel. Yes, the V10 has a lot less torque, but what matters is what comes out at the wheels.

10.5 MPG in traffic is pretty amazing, and to boot, you don't have to buy DEF that is another fuel charge.
