I had a 00 V10 CrewCab with the 5 speed and it got up to 16mpg, usually around 12 to 14 though city. Pulling my 5th wheel Jayco travel trailer it got 8 running down the interstate at 60 and 65

The mpg's arent going to be MUCH better on a diesel and with the v10 its going to be cheaper running cost's than a diesel

My friends 6.0 crew cab 4x4 long bed stays around 11mpg in town and close to 15 on the highway.

 

When gas is $2.89 a gallon and diesel is $3.69, a gas V-10 looks pretty attractive. 6 or 7 quart oil changes are more attractive than 12 to 15 quart changes too. Then start comparing fuel, air, and oil filter costs.

 

Diesel IS 25-30% more expensive, but a diesel can get 60% better mpg. I wouldn't expect any better than 10-11 on a V10 and a 6.0 should get at least 16 with an EGR delete. But the maintenance would still be a big deterrent for me.

 

My truck is averaging 15.3 with 18 being the highest and 13 being the lowest I've gotten so far over 13,000 miles and 775 gallons of diesel.

Oh and my truck has 201,000 on it.

 

Shouldn't get slammed for that. My dealer friend wasn't fond of 6.0s until...he found a couple to sell. He drove them around. Then he pulled them off of Craigslist. He took to them. They were already dealt with by Ford, so he didn't get the bugs with them.

That, too. I was Super Duty hunting last year, but try finding a 7.3L truck for a decent price and without miles on them, too! Silly hysteria over issues that Ford pretty much dealt with already way back when. I guess you shouldn't let that cat out if you go 6.0L hunting then. My bad. The 6.0L trucks were cheaper and just flat out better performers as my friend found out. The 6.0L gets about 50% better MPGS than his 7.3 trucks no matter what in his case.

Because it costs many millions of greenbacks to certify a drivetrain for use via the EPA and when 99.44% or more of the driving population can get by with an auto trans just fine...so that's what you get. If your amigos are that mad, then I am quite sure Ford will take their donations.

 

Idk I'd get a v10 I'm worried about the mpg tho. Still would like a diesel tho

 

How the hell do you figure that? My 6.0 gets 19-20 highway as long as I don't get much over 70 mph. Pulling this this horse trailer with 3 horses (9000 pounds) I get 13-14 mpg all day long driving about 75 mph.

 

Maybe your 6.0 is special? I know alot of people that doesnt get close to that mileage you get with yours and they are running bone stock 4x4 crew cab 6.0's.

 

All I have done is EGR delete and SCT trans only tune (stock engine tuning). Truck has 3.73 gears with factory 20" wheels and stock 34" tire size.

I will say, the EGR delete made about 1-1.5 mpg increase on the highway. I never pulled anything with the EGR still in place. I will also note, if a 6.0 has 4.10 gears, mileage drops off quick. If you drive around 75 mph or higher, miliage drops quick. Pretty much, as long as I'm under 2k Rpm, my miliage will be up.

 

Glad your having great luck with the truck

Im just saying that over the long run the V10 gas engine will be cheaper to run Even if it gets 5 to 7mpg less than a good 6.0 diesel.. After oil changes, extra cost of diesel and when the time comes some pretty expensive parts..

Thats the reason my buddy is selling his 6.0. He got 280k out of it and now it needs head gaskets along with egr and no telling what else. He dont want to put 7 to 10k into a 13 year old truck.

Now if the Op finds a 6.0 that has all the upgrades and the work has been done RIGHT then there shouldnt be much worries. They are bad *** motors when done right

 

Op

Heres a nice 99 f250 7.3 4x4 6 speed manual with only 119k on it.. Low mileage 7.3's are around you just have to pay top dollar for em

Ya I can't argue the lower cost of a gas rig. I will say, there is no way I can go back to pulling with gas engine though. That step up into a diesel's torque band is a league of it's own. I'm spoiled now. Haha

I would strongly suggest to a guy that was buying 6.0, to buy one with lower miles and get the EGR delete right away. That system is the number one cause of most 6.0 issues. If your buddy got 280k with the EGR in place before gasket failure, then he done great in my opinion.

 

A low mile 7.3 would be something to think about too. That is a nice truck ^. 7.3s are amazing engines, but a little blah with stock tuning. They can take a hell of a beating too.

 

Thats exactly what i told him! Maintenance was his number 1 priority on that 6.0.

He had a 96 or 97 7.3 he had 340k miles on it and it was bone stock, Transmission started slipping and it need a HPOP so he traded it in on the 6.0.

He got that 6.0 and it seemed like a 800 hp truck compared to the 7.3

 

Sounds like it proved me right

May just be me, but I think the 94-97 7.3s look the best and I'd definitely want one of those over the new body style. I think the older ones look great.
