Just wanted to get an idea of the kind of mileage you can expect out of a diesel pickup truck before it gives up the ghost. I have a 99' F250 with the 7.3 Powerstroke. I currently have 157,000 miles and it runs great. I have the 6 speed manual transmission since I pull a heavy trailer in my business and figured the manual would be less problems down the road. I have changed the oil every 3k miles unless I haven't been pulling the trailer then I'll go 4k between changes. I keep up with the fuel & oil filters as well and keep the coolant additive in spec. I'd like to hear from all diesel owners, not just Ford as I'm in the market for a new truck and don't suffer from brand loyalty blindness.Everyone I know that has the new 6 liter Powerstroke has had problems with having to get the "brain" reprogrammed. I wonder if this issue has been sorted out?
Thanks,
John

My limited expierience...

'89 Ford F250 4x4 xcab long bed 4x4. 351ci fuel injected v8, manual tranny. I sold it at a little over 225,000 miles. Ran like a toip, didn't use oil ect. Only work that I know of to the engine was a water pump, and an electrical part in the distributor. I know it is not diesel, but... That truck had plenty of mileage left to go, with proper care.

My Dodge, '01 Ram2500 4x4 xcab Cummins/auto has about 83,000 on it. No problems /forums/images/graemlins/wink.gif

My Dad has worked for Dodge as a mechanics/shop counter parts guy since the 1960's. A couple years ago, they had a couple guys come in with 500,000 and 750,000 miles on thier trucks(Cummins/Ram)(98 and '99 I think...). No major work besides regular consumables(brakes, fluids, tires ect).

The key to some of the real high mileage rigs is running them, not cycling them. If you start, stop, start, stop, heat-up, cool-down any engine, the life will be shorter; most wear occurs on a cold engine when the oil is at the bottom of the pan...

As a rule, and some might disagree, a diesel engine thats well taken care of can run seemingly forever.. What I mean by that, everything run through it should be lubricated(fuel, oil, and coolant), along with clean air(dont fall for those "2 letter" air filters) the engine should not wear much at all.. I have seen 300k 7.3's that still show the crosshatch on the cylinder walls.. I know of a 6.0L that already has 500+k miles on it.. I have heard of 600+k mi 7.3's from techs.. If its taken care of , your truck is just broken in, you'll have issues with bushings and springs long before the engine fails..

As for the 6.0L, there have been some programing issues, each year has its own.. Its a small inconvenience to make it run right.. Remember when you talk to people about their P/S that with somewhere in the neighborhood of 300,000 diesel trucks produced in a given year(by Ford alone) your bound to find someone that has had trouble.. I would immagine your 7.3 to last into the next generation anyhow...

I really have no "bad" news for you. I've been in the industry to have access to literally hundreds of thousands of breakdown claims. I do NOT take my advice from any publication that may have a lot of advertising dollars hinging on whether the next write up for their truck will be favorable or not. Also, I've seen "great" mechanics who make their entire living fixing vehicles who had absolutely no clue as to the actual comparative analysis between similar vehicles that include important factors which not only include frequency of repairs, but many other variables such as severity as well. Basically, what I'm saying is that I do have lots of friends in the business, but I make my decisions on rating and rates on actual facts on actual repairs. I deal in pure facts. Emotions have no place in what I do.

First, on your '99 PowerStroke. Keep it!! If what you tell me is correct and you do maintain your vehicle as you say, you're not half way to statistically having expensive repairs appear with any frequency. Your take on the transmission is also correct. You can get an automatic transmission for a Ford, Dodge, or GM that will hold up over the long haul even when hauling heavy loads, but that will cost you (with labor) over $8,000.

The 6.0 liter replacement for the venerable old 7.3 has already been phased out. As to not upset anyone, I'll just say that Ford agrees with the actuarial data that says the engine is not a winner. I think the slated replacement for '07 will be a 6.6 or 6.7. I obviously have no data on them.

Although I personally own a Dodge truck, I prefer the Ford truck (other than the power train) better. /forums/images/graemlins/blush.gif Not that it will ever matter for most people, it will not be uncommon to see 300k to 600k on your 7.3 PowerStroke. You can about double that for the Cummins. /forums/images/graemlins/shocked.gif Also, in every diesel drag race bracket and every truck pull bracket, the Cummins is the world record holder. Bluntly, more power and more reliability if you can take the box around the powerplant.

The GM offerings is a tough issue for me. Most all of my relatives are die hard GM fans. The 6.2 diesels were terrible. The 6.5 were not much better. The "savior", the Isuzu Duramax has had more than it's share of issues as well as the stock Allison "bulletproof" transmission. But, GM seems to have the strongest following and they are also addressing their short comings in the diesel area. They better, Toyota is close to bringing out a 1 ton diesel here in the U.S.

The bottom line: what do you like? If you like your Ford, stick with it another couple hundred thousand miles while you figure out your next move. If you can take the truck (and I've gotten used to mine) and want what is simply the longest lasting and strongest pickup diesel engine, go with a Dodge. If you don't mine shifting gears, go with a stick. If you go with an automatic, just figure on dropping about $8000 after you run out of warranty and you'll be done for life there. I've lit up all 4 rear tires on my Dodge and have about melted them off of the rims on several occasions with no ill issues with my expensive aftermarket tranny.

If you want to fight the brand wars with others, feel free. I go by stats only. I assure you, otherwise, I would not drive a Dodge over a Ford. Besides that, I can run in the high 13's in the quarter mile with my 4X4 dually with a 4" lift kit that weighs 8000 pounds. That does have a certain fun factor. /forums/images/graemlins/cool.gif

I was leaning toward a Dodge for a replacement but I was concerned about the transmissions. I have talked to folks that have had problems with the manual 5 speeds and the auto is out of the question. I understand that they have a 6 speed manual now, how are they holding up? Have they got their auto trans beefed up? I know they were somewhat problematic when used for heavy towing. Also, what type of auto did you put in yours Dargo? It sounds like it will do the trick but the 8k price tag is a stickler.
Thanks,

John

Unless you drive a lot of miles per year (or are abusive) - the chassis will likely wear out (or you'll want a new truck) long before the engine (whether it be gas or diesel).

The real reason for buying diesel is the incredible low end torque that makes driving an absolute pleasure (power on demand)

My two cents.

Just to add a little......

The new Ford engine will be a 6.4L Navistar with common rail injection through peizo injectors..

Dodge is also releasing its replacement diesel next year(last I heard) for their sake, I hope its as bulletproof as this generation..

Both are due to the stringent '07 emissions.. The current engines will not pass... We'll get another set of new engines(or modified versions) in '10...

BTW, about the trans.... I prefer the auto, but I wouldnt race the truck /forums/images/graemlins/grin.gifso the $8k version would be overkill to me.. With a temp gauge and extra cooler on it, maybe even a shift improver along with regular maint I like my chances with the Ford auto, especially the TqShift(I've ridden in a 4x4 with 450hp and if I remember correctly about 900lb of tq, talk about impressive, it aint broke yet).. I have no experience with the Dodge auto, but I havent heard any good about the stock box /forums/images/graemlins/frown.gif...

You forgot the twin sequential turbos on the 6.4... /forums/images/graemlins/cool.gif

I figure my 99 F350 PSD stick to last and last... The only reason I might upgrade would be to a dually flatbed. Just change the oil regular and keep the air filter clean...

I also run a 3qt oil filter... can't hurt.
