diesel question
 
i know this is a little off topic. i am looking at a pre owned truck. i need a truck with 4x4 .

i found a 2002 ford f250 diesel with the 7.3l 8 cylinder with only 31k miles! i just need some info on gas vs diesel maitnence to explain to the wife. any help?

do you haul/tow lots of stuff or push a snow plow?

seems like a lot of truck unless this is what you do.

maintenance shouldn't be that different from a gas engine, although the intervals for various services might differ.

Maintenance will be about the same between the two is my guess, perhaps a bit less on the diesel. The diesel would likely last longer and use (a lot) less fuel in the long run too. I've ridden in a 2002 7.3 liter ford diesel....they are pretty awesome. Guy I knew with one had 128k on it since new and had hardly had to do anything to it. And it has some POWER.

i do haul a 7000 pound trailer and i do plow snow, i am definately getting a 2500 series, i am familiar to diesel maitnence as i have a few old mbs although they are struggling to stay alive. i need to convince the wife diesels better, shes stubborn.

There was a recent study at the medical school of UCLA showing that males exposed to diesel fumes held their erections for an additional 1.3 minutes on average.

First, the 7.3 was the best engine of the 6.duh, 6.4 and 7.3. That truck has plenty of power for most whatever you are doing, especially if you stay within the ratings for the F-250. Mileage is an issue that will vary, but most will get 16 to 22 unloaded. Much better than the gasser. Resale will be much better as with 31K miles, it is barely broke in.

BTW, I have a F-350 CC 4x4 dually (auto), and when stock, I would routinely get 19 MPG unloaded as long as I stayed under 65.

It just has no torque off the line.

The diesel will get way better mileage, especially when towing, and will last longer. You may find more specific information here: http://www.thedieselstop.com/forums/

Keep a bottle of power service fuel additive in the truck and use it every fill up. Oil will cost more as there is a lot more of it. If you switch to synthetics and run a bypass filter it will run forever on the same oil as long as you keep up with the filter changes and do the required periodical oil analysis. The trany is the weak link as heat will kill it. Make sure you have a big trany cooler and try not to back too far for too long with a heavy load or up a hill as there will be little airflow through the trany cooler. Stay up with the SCAs (coolant additives) as these blocks are a little thin and are prone to cavitation. The 7.3L is by far the best of the Ford light duty diesels and the 7.3L will have plenty of power off the line unlike the others (6L & 6.4L). Keep the fuel filters clean and free of water as the injectors for these trucks are over $80 each and the injection pump is around $1800. A great engine in a great truck and these 3/4 tons tow better than the old one tons and with today’s electronics you just plug in a chip and boost the hp/tq just make sure you have the gauges to keep an eye on it.

Quite the opposite. Floor it and the 7.3 will make a lot of noise and eventually start moving, the 6.0 will wait a second then launch and the 6.4 has more power off the line than those two combined.

How many of these Fords have you owned/driven? I have owned mine for seven years now and have driven the PS 7.3L and the 6L as well as the 6.2/6.5L Chevys for the government for the last 18 years. I did recently test drive several of the new 6.4Ls and while I love the idea of another 390 cube engine they were all quite lacking compared to the ol 7.3L or even my 7.3L IDI. In my experience you cannot replace cubic inches with a turbo for off the line in a big truck. I will however admit that once you start tweaking these electronic nightmares, they all scoot right along.

Oh, I just used to work on a fleet of 150 2000-2003 F-450's. :D Manual or automatic, they all made a lot more combustion noise than power.

Well you do get a lot more work out of those engines for the amount of oil you need.;)
