I recently bought a used 2002 F-250 Super Duty Diesel of which I was assured had received a full tune up before leaving the dealership and of which I had recently changed the oil. I was travelling down an interstate at 65 mph when there was a sudden power loss and the whole truck shutdown. There was still power to turn on the hazard lights and I had the alternator checked just about three weeks ago when I replaced a dead battery. The transmission fluid seemed to be at a good level. The starter seems to be working, and the truck wasn't indicating that it was overheating. The only light that lit up after the truck completely shutdown was the air filter light. Has anyone had this occur to them? Do you have any idea of what might have caused this? Any suggestions you may have would be helpful. We had to have it towed. Thanks!
I have put about 700 miles on it and seem to be getting 12 MPG. This is a mix of highway and city with most being city. My drive to work is 11 miles one way with about half being on the highway traveling 65 MPH. I have been keeping the RPM's under 2000 when on the highway. I was hoping for better mileage than this. I have been told several times it should get 17-19 MPG and on some occasions even 22 when all conditions are favorable. I have been told twice that the mileage may not be that good until it gets 12-14 thousand miles on the engine.
So, with that, what have you folks been getting for MPG? What do you think it should be getting. Did you notice a mileage increase after several thousand miles being driven?
I do not want to do any other alterations as far as the engine or "chipping". It already runs great and has PLENTY of power. I do plan on re installing a pyrometer gauge since the thermocouple and wires are already there.
Thanks for your input.
pretty good. Twice a month I take a 500 mile trip all freeway with mine. All Stock
@ 72 on the cruise I get 22 MPG. If I didn't get good mileage with it I'd probably
sell it. This is the best diesel I've owned...had an '02 Excursion and '04 F250 all
diesels, never got good mileage with them. Finally found one that did. All that
after market stuff turns your truck into the "Money Pit" like the movie. Have a Nice
Day.
I checked my speedo with a GPS also and found it to be 4 or 5 MPH slow . I just can't believe this thing won't get better mileage. I am REALLY hoping it gets 17-20 when I get a few more thousand miles on it. Other wise I should have kept my Dodge with a 360 gas engine.
I would like to hear more input from others and their mileage experiences.

Also, has anyone had their speedometer recalibrated for different size tires? I have been told that a dealer has to program the computer. But, I see what appears to be a small gear housing on the transmission. My '97 Dodge had this and all I had to do was change out the little gear in that housing. Took 5 minutes and got the speedo right on. The dealer wants $80.00 to recalibrate.
Make : FORD Model : F-250 SUPERDUTY Year : 2005 Manufacturer : FORD MOTOR COMPANY Crash : No Fire : No Number of Injuries: 0 ODI ID Number : 10134178 Number of Deaths: 0 Date of Failure: August 23, 2005 VIN : 1FTSW21555E... Component: STEERING Summary:
F250, SUPER DUTY, 3/4-T, 4X4, 4WD, SHORT BOX. ALL SPEEDS IT IS NOTICEABLE. AT HIGHWAY SPEEDS (75+ MPH), ENCOUNTERING BUMPS, SEVERE SHIMMY IN FRONT END, NEARLY CAUSING LOSS OF CONTROL OF VEHICLE. FLEET OF 7 TRUCKS ALL EXPERIENCE SAME, SOME WORSE THAN OTHERS. DEALER HAS DONE ALL POSSIBLE TO REMEDY, INCLUDING AFTERMARKET HEAVIER DUTY FRONT STEERING STABILIZER (AT OUR EXPENSE). INCIDENT DATE IS LAST DATE IT OCCURRED TO MY CRUISER TRUCK. IT HAPPENS EVERY TIME A BUMP IN THE HIGHWAY IS ENCOUNTERED WITH EVERY TRUCK OUR DEPARTMENT BOUGHT FOR USE AS LAW ENFORCEMENT VEHICLES. THE MAGNITUDE OF THE WOBBLE IS DEPENDANT ON THE SPECIFIC TRUCK AND THE SPEED TRAVELED. REALIZE THAT AS LAW ENFORCEMENT RESPONSE VEHICLES, OFTEN THIS INVOLVES VERY HIGH SPEED. THE HIGHER THE SPEED, THE WORSE THE PROBLEM.
Firt time user of these forums & I got a question. Recently, my truck will change its idle sound. I dont believe it's slowing or speeding...just gets quiet.Lasts about 2 secs....then gets louder. Happens across the time map. Sometimes when I first warm it up, other times after driving 140 miles..?
This is my first diesel, so bear with me if these are stupid questions. The guys at the dealership just hummed, hawwwwed & could tell me nothing. Mind you this is after getting shuffeled around from person to person.Felt pointless, kinda like picking fly [non-permissible content removed] out of a pepper mill.. :P
Thanks!

Few questions: Did he use a coolant additive to prevent cavitation? (Cavitation is bubbles in coolant that can actually erode the cylinder walls and decrease engine life.) Did he tow with it or plow snow? Did he do any engine mods or chip it? If he was conscientious about the maintenance, didn't beat on it, and the rest of the truck is stock, then the truck should be almost worry free.
Few points to check.
Diesels with their heavy front ends are rough on the ball joints - Ford cheaped out and didn't put grease fittings on them, so the ball joints could be getting a bit creaky by now. The lifted truck also adds to increased chassis wear. Diesel Superdutys are also tough on brake rotors - lotsa folks needed to turn rotors quite often to get rid of brake pulsation.
If he towed with it, there is a chance that he overheated the tranny. The auto tranny was a bit of a problem for folks who towed heavy loads. But from what I've heard, if they were gonna fail they usually failed at lower miles. Many added tranny temp gauge and supplemental coolers to improve reliability if they towed.
If truck is chipped, then there is potential for higher exhaust gas temperatures, which in turn could cause oil break down and premature turbo bearing wear. (THis can also happen if truck towed heavy over long distances and big hills.) Best thing to do if you've been pushing hard is to either drive slowly or let the truck idle for a couple of minutes before shutting down. It allows the turbo to cool down properly and you avoid the oil break down problems
In general, Diesels require a bit more maintenance than a gasser. Need fresh, clean, water free fuel. Regular fuel filter changes. Oil changes are 16 quarts, filters are more expensive. A bit more finicky to start in cold weather. Need to wait for glowplugs to warm up before starting in sub freezing temperatures. In sub-zero weather you will probably need to use the engine block heater.
Diesels get better mileage than a gas engine, but right now diesel is anywhere from $0.25 to $0.40 per gallon more expensive than gas,.... in my area anyway.

I have a '04 F250 w/6.0L diesel engine. The truck has less than 12,000 miles on it yet it has stalled 4 times in the past 15 months. Usually the engine stalls while going less than 30 mph. The dealer has come up with various diagnosis to include faulty ERGx2, "I don't know but the engine oil weight is too heavy" (for 15W30).
My truck is not on the recall list but the dealer ran diagnostic anyway without them finding any problem. Has anyone dealt with their super duty trucks stalling on you while driving? Do you have any further info? Thanks for your time in advance.

I just purchased my first diesel (wife has horses and trailer). It is a 2000 7.3L Powerstroke with 118K miles. SuperCab with long bed. The truck was sold to me from a small dealer who got it through an auto auction. Needless to say, no maintenance records. I had the local dealer check it out and repair a few items. My question (that the dealer couldn't answer): The turbo is louder than normal. The dealer said it could be OK and go another 100K, or not. The noise (high pitched sound) is most noticeable, when accelerating, and quickly backing off. Any ideas if this is serious, or if I can expect another 100K+??
Thanks
If the "loud" noise is like a whistle that rises and falls with power application, that is a good sound. If what you're describing is more like a roar, then check the clamps to and from the intercooler. Usually a few twists with a nut driver on each coupling band, or clamp will do the trick. Also, you don't want the system to be sucking unfiltered ambient temperature air, so it is a good idea to check the tightness every 10,000 miles or so, as a part of maintenance.
I have a 2006 F-250 Super Duty with the 6.0 Powerstroke. With just 1200 miles, I have had the "Check Engine" light come on 4 times now. The dealership replaced the fuel sending unit 2 weeks ago after 3 of these lights and this morning - just 2 weeks later - the light came on again! From what I understand, the "CODE" has been the same each time! I have an appointment with the service department again tomorrow. Any ideas???
thanks,
Mary :confuse:
