my 99 drw 3.73 crew cab standard had a historic average of 11.8 city and rural driving short distance. pulling 13,000# 7.5 to 8.5. Sometimes it would spend 20minutes on the floor. Being a chevy person, I did not like the v10 at 1st but after 5 years of hard towing it really proved its self. If I wasn't updating our camper to over 16,000# would have bought another V10. Just wish they made 4.88's available with the V10, then it could tow over 17,000#. So far my new 450 6.4 has a historic average of 11.7 city and rural driving too.

 

I concur with the postings already on here. Running around empty on the highway (below 70 or so) with my 2005 CC LB 4.10 V10 we'll get 13ish. Short trips around town (5-10mi) brings it down to about 10-11. Towing 10-11.5K is 7-9 depending on wind mainly.

 

I get 10 mpg in city

8 mpg towing 11K 5th

12 mpg highway

 

diesel power mag. the new one for this month just did a side by side with the 08's. a v10 and a 6.4 they got just what we are getting with a 08 dualie f350 8mpg's on a very tight motor.

 

Yeah Chas, there is a thread on RV.net going on about that article.

 

Wow, read the report on rv.net and I gotta agree with the guy on pg 2 who thinks the deck was stacked against the V10... both in power and economy results.

Hop over to that diesel site whose name can't be mentioned here (diesel and stop and dot and com) and take a look at the economy thread in the 6.4 forum. Most of them are getting the same MPG as our V10s!

 

Would have to agree with you for the most part. My 450 6.4 with 4.30's and my 99 350DRW 3.73's are getting the same milage. So it is a little like comparing Apples to Oranges. The new 6.4 with 3.73's do get better. New to me going from a V10 to the Diesel, we are finding that going over 2,000 rpms with the diesel, just kills fuel milage. At 65 mph 2100 rpms I get 12mpg on the computer and drop it down to 60 mph at 1950 rpms 16mpg. The one big difference is my 450 can tow 20,000#. If you do not need that much capacity it sure makes sense to stay with a V10. If we were not trading up our 5th wheel to over 16,000# I would have stayed with the V10. It is really a great proven motor.

 

It's a downright shame that the efforts to placate the EPA are creating such a fuel INEFFICIENT vehicle. What a waste. Diesels used to get 50% better mileage than gassers and now that is gone. Maintenance costs on a diesel are far greater than the v10 also. The only thing that is an advantage is the POWER, and it truly is an advantage. No going up mountain grades in 2nd gear for the oil burners. They leave it in overdrive and accellerate from 70 - 80 whenever they want to.

 

Im a powerstroke guy but I find this thread very interesting.Whats the most miles you have saw on a v10?They sound like good engines!

 

I have 168K on mine and the only trouble I've had is the exhaust manifold studs breaking. The guy at the shop that installed my last set of headers, said he had worked on v10's with 309,000 on them.

 

I have a 2008 F-250, Crew Cab, 4x4 V10 with 16,000 miles and have seen an improvement over the last 3-4,000 miles of about 2 mpg. I'm getting around 14mpg highway driving in traffic and around 10-11mpg pulling my 27 foot toy hauler @ 9,000lbs. I had a 2002 same exact truck and I'm getting better mileage and a ton more power with the '08.

I can get 16MPG on the highway if I try - or not.

I get as low at 4 around town hot-footing it all over the place.

I can get up to 10-11 around town if I take it REALLY EASY.

--

Total miles before something breaks? 200K? 300K? We've had people reporting those numbers and STILL driving them around. One guy asked about a 400K+ truck once, and almost no one was against it because it was all highway miles and if taken care of, no problem.

The low-tension rings, silicon/aluminum bearings, a REAL timing CHAIN (not a belt) and lots of other things that Fredvon4 can expound about more than I can, and the V10 is an amazing thing.

If you can stand the fact that you can't buy a $500-1000 tuner and extras, and get so much power you'll wrap the truck around the driveshaft, the V10 is for you

 

for some unknown reason! most of us found the v10 seems to beheld back when new. at about 150 hours or 7.5k and over they start to run much better then when new. at that point the mpg's went up and power levels did the same.

thing that is making a lot of guys look more then one time at the v10 ver psd problem is the psd's cost. well over 6k plus another 1.5k for the manditory auto trans ver the 600 dollar v10 price and the same 1.5k for the auto trans.
yes the v10 has it's draw backs. but sure dosn't come close to the cost of 7.5k plus when you figure in how long it takes for a psd to make the pay back point. with that i mean mpg's and higher cost of maintance for the psd ver that of the v10. how many miles do we have to drive to reach that point? how many miles per year to reach that point?

we all have some tuffies ahead of us to consider when buying new. but thenif you go up top and read some threads in the new 09 f150 area. seems that the big 3 are going to be doing some very hard diesel pushing with the soon comeing out cgi engine block machining machines they have ordered up. good reading up there guys and time for us all to play catch up on the news comeing out.

gm will have a new 4.5 v6 diesel. ford a 4.4 v8 and a 6.7 v8 if i did read the thread correctly. even chrysler, audi and vw have gone ahead with that casting tech. but then vw has used this tech for a few years and had it before i retired from them any way.

time to sit back and see what happens in the very near future!

 

I agree about the changes coming down the pike. I'm afraid with the new emmissions requirements however, that there will never be a time where the diesel saves money. Look at it now, fuel costs more than gas, maintenance and oil changes are much more expensive and finally the real nail in the coffin is that the diesel MPG's have dropped like crazy. You used to count on the high teens or even low twenty's for the Superduties. Now they're getting only a mile or two per gallon better than the gassers. I've said it before, but it's a terrible shame. The EPA places restrictions on emmissions only to cause us all to use way more fuel. Government logic, but I digress.

Bottom line is about the only advantage of diesels over the v10 is plain and simple power. And there's a great argument for that.

 

While I agree with most of what has been said about the milage of the diesels, I don't think we can blame it all on the EPA. The icreases in power have to factor in also. A freind has had several over the years. 7.3 turbo, 7.3 PS, two 6.0s, a 5.9 Cummins and now a 06 Dmax. The Dmax makes less mpg than any of the rest but still 100% stock pulls at least as strong as any of the others that were chipped with intake and exhausts. More power takes more fuel.
