Default Diesel truck questions...

How many miles are ppl generally getting out of a diesel engine and transmission? Not looking for specifics, but general use issues so I can know what I'getting into. Thx...

Here is a thread on a Dodge Diesel Site that asks the same question.

http://www.dieseltruckresource.com/d...s-t115198.html

It's a good site with lots of information. I've got 42,000 on mine with no problems, but that's barely broken in good. I think a well taken care of truck should last a couple hundred thousand without much more than standard maintenance.

Also, in case you did not know the 3rd generation trucks the poster is reffering too are 5.9L CTD's (manufactured through 2007.5) not the new 6.7L (2007.5-Current).

Hopefully this helps a little.

Most trannies will go 150k If you baby it it will last alot longer Most desiles will go 250k without hesitation And the good ones like the 7.3 powerstroke the 5.9 in all the different configurations with the 12 valve being the best for alot more

If you drive a lot of miles and/or pull loads, then diesel is the only way to fly.

I drive very few miles, but launch and retrieve a 9500# boat, so my 7.3L Excursion does the job just fine. Getting 19.5MPG around town in that monster truck is nice, too.

Mark,

I have a Ford F350 crew cab work truck that has over 250K and runs like new.

A friend of mine had the same truck and put 300K on his before his company bought him a new one and the truck he had was turned over to a junior foreman. I believe it still may be in service.

I drive a Ford F350 Diesel crew cab King ranch Dually, The real boss's truck and I can't bring myself to get a car. I've been driving Dually Fords for years now and I just love the truck. Sure makes it easy to drive around on job sites. Plus I don't have to worry about the smell bait flats tend to leave.

70K is nothing for a diesel. As long as the air and fuel filters and oil has been changed on regular intervals I wouldn't hesitate. Most people that own diesels take time to get the maintenance done.

If it's a big truck you're looking at even better, because those guys almost always take care of their truck.

Plus you can always send some oil out for analysis.

203,000 miles on a 2002 Chevy Dmax/Allison and still going strong. Towing 3-4 different trailers on a regular basis. Heaviest is 10k lbs and lightest is about 3k lbs empty. Fishing trip is 350 miles round trip towing. Truck has been phoenominal except for injectors (common problem on 2002-03 Dmaxs). Total repairs/maint items to date. 1 bad U-joint, 1 water pump, 1 set of shocks, 1 front brake job, 2 sets of injectors, 1 windshield, trans fluid and filter twice, oil change every 10k miles, air and fuel filter every 20k miles. Still haven't had a front end alignment or rear brake job. Getting about 70k miles per set of tires, 20 mpg hiway and 16-18 mpg city. Planning to hit 300,000 miles with this one. Last 2 gassers went 250,000 and 275,000 miles before I sold them.

And I haven't "babied" anything including the trans.

If your going used try to stay away from any of the newer EPA'd to death models.

Example: Dodge Cummins 5.9 up till mid 2007 is OK, after mid 2007 they went to the 6.7 with the Diesel Particulate Filter (DPF), worse economy, more to go wrong etc. So if your looking at 2007's get the slightly older model. I expect Chevy and Ford are similiar in this.

I have a 2008 Cummins with the 6.7 and 6spd, love it at 22k, but it is going in Thursday for pollution related check engine light (1st time). The major fix will be updating the firmware, cleaning the soot and the sensors.

Don't know what your towing but watch the rear axle ratios, at todays fuel prices every litttle bit helps.

Just my 2

go over to thedieselgarage.com and you will find out all kinds of info. As mentioned the newer trucks get worse fuel economy than the slightly older versions. what brand of diesel are you considering?

07.5 diesels all have the EPA regs applied. They have self regenerating catalytic converters call DPF - Deisel Particulate Filters. Computer tells engine to burn extra fuel into the DPF to burn off the soot. Hell for MPG.

That being said..most diesels will easily get 250K with routine maintenance. Oil, Fuel filters are a must. The Allison transmission on the GMs will mostly outlast the engines.

I have a dodge with the 5.9 24V. It gets 21-22mpg at any speed being 45mph or 90mph. Towing 10,000lbs of boat at 75mph,it burns at a rate of anywere from 13-15 mpg.

Problems,1 water pump,1 set of injectors when it was new. Thats it,but it only has 62,000 miles on it.

With the cummins being a true diesel I'd be shocked if the engines doesn't give the owner at least 500k under normal use. Personally I'm expecting/ hoping to pull around the 750k mark before I'll have to tear into her. I am hard pressed to believe the same numbers could be achieved out of either the Ford or GM fake diesels.

I have a guy "in the biz" looking at auction trucks for me. He does a great job and I've bought several cars this way. We'll see how it chakes out. Thanks again...

How are the Ford and GM not true diesels?

Last I checked they all burned diesel fuel and they all have a pretty good reputation.
