Diesel seems to be a fad for many, even those that never tow.
I am looking for an older used truck, and selling my '08 diesel F350.
I've considered that a lot. My 7.3L got much better mileage and had about the same power. It is a lot of money I wouldn't have to spend if the truck wasn't such a fuel hog. I tow a lot and it's very heavy so I get hit pretty hard. Trouble is, the 6L Fords have a lot of problems. Some say the 06 and 07 models are OK, I don't know. I do know the 7.3L is a fantastic motor and gets much better mileage. Trouble is they haven't made them since early 03 models. So. the trucks are old and the trannys are old fashioned, no tow haul. Plus, the price is high because they are in demand. There is an 02 DRW with 60K or so miles on the ATL craigs list, price is 28,000 dollars. I only paid 30 for my 08. Even the 7.3s with 150,000 miles are going for 15,000 dollars or so. 7.3s that are 10 thousand dolars or less have 200,000 miles or so on them. I tell ya, it's enough to make a guy consider buying a Dodge, NAH.

That 454 is a gutless wonder. If...you could gross out at around 30K with it, you would have to have to the floor the entire time.

7 mpg might be optimistic.

Diesel Fuel Prices
nice read on diesel fuel prices.

Energy Information Administration (EIA) - The Transition to Ultra-Low-Sulfur Diesel Fuel: Effects on Prices and Supply
lots of information on ULSD transition; note the 2001 date; thank you to Bill and Al.

http://epa.gov/cleandiesel/documents/420r09006.pdf
I feel better knowing the government is in control Wait till healthcare is fixed.

The good thing is that technology will help allow some of the regulations imposed by Congress and the EPA to actually work.

Generally when the government gets involved; I agree, we are screwed

Imagine if they would have had the torqueshift behind the 7.3L for a year, those would be incredibly high in demand. Would also be interesting how well their mileage would have been. We've now owned every generation from the IDI 7.3L's and from the DI 7.3L's the mileage has just gone down and down with every new engine. Hopefully the 6.7L will correct that.

GUTLESS you say.

the 454 pulled good and all it had was a RV cam and headers.

It averaged 8 MPG overal in the time I owned it.

Just towed 1200 mi. on I-80 from OH to Rawlins, WY where I am tonight. I'm hauling a high profile 5er at almost 17k ... had the cruise set at 64-65, helping out before going uphill, etc.. My '08 350 was doing regens almost every 60 miles after Des Moines, and for almost 40 miles up the mountains west of Cheyenne. The last 400 mi. I have gotten 6.6 and 6.2 mpg, respectively.

These regens are killing me. I am ready to buy a DPF delete kit just to get rid of them. I could care less about the tunes... just don't want to see "Cleaning Exhaust Filter" anymore!!

Something is wrong if you are regening for 40 miles. I averaged regens about every 130 miles and about 10-15 miles per regen on my trip out west to colo in July.

I think you need to have it checked out.

How do your tail pipes look?

I think Sennix is right, somethings wrong. I have an 08, DRW, 4.30 towing a 17K lb mobile suites and made that same trip in July except I got on I 80 at Lincoln NE. Drove on cruise for the most part at 59-60 MPH, averaged 8.45 into cheyenne, 8.8 cheyenne to Casper and 9.3 casper to Cody. I did have a major regen when I got to cheyenne, must have lasted 20 mins, but they didn't seem to come any more often that normal. I had a 6000 mile tow on the trip and over all mileage was 8.45. My two lowest legs were 6.8 and 7.6, both over big mountains. That's just what these trucks do.

I think the MPG thing is part emissions and part power. It takes a lot of fuel to make 350hp/650torque. Then the emissions stuff doesn't help.

It's sad really that the 6.4 gets such terrible mileage. Even our 49000lb, 425HP pumper gets 3MPG with a lot of idling and in city driving including making calls. Heck even truckers get around 4-7 with 80,000lb rigs.

Well, towing with the 6.7/6 speed auto/3.55 has me pretty happy. I used to get 8-10 towing my usual loads, now I get 11-12. This is running speed limits, which means when it's 70, I go 72 - all day. Those of you that get 8-11 running at 60-65 mph with your 6.4's should get better results than I am seeing.

I am towing a 10ft tall, 18ft cargo trailer that weighs around 9K loaded with my gear. My 6.4 would rarely get better than 9 with this tall trailer, I averaged 11.6 this week over 800 miles.

Now, I agree that we are just plain "screwed" when it comes to fuel, emissions, and pretty much everything else. Well stated Stanley.

I do not agree that we "might as well be driving gassers". I am much more confident on the road running a diesel engine at or over 80% load on a daily basis than I would be running a gasser at 80% or higher load. It's just an opinion and I can't back it up with fact. I just "think" that running a gasser at high load for extended periods of time is gambling, probably much more likely to experience part failure of some kind.

Let me add this, when using a gasser I always found that I had to really stay in the throttle, no cruise and really had to drive the truck.

With a diesel I can use cruise and pay attention to the road and my load, not so much the truck.

This has already been happening to things small as chainsaws. There are several models out that have catalysts in the mufflers in order to meet the newer standards for 2 cycle engines.
