You missed my point. Ford has put everything from 140-inch 4 cylinders to 429-inch V8s under the hoods of Mustangs - all of them will move the load that a Mustang is capable of carrying. But if you need to carry more than 4 people and a lot of cargo, even a 429 Mustang won't get it done, because there's no room or weight capacity. You need a larger stronger vehicle to do it. As Chevy showed a few years back, a 454 can get under the hood of a half ton, but are you going to pull a fully loaded horse trailer with a 454SS? The GMC Syclone had a nearly 300hp turbo V6 under the hood, but it only had a payload of 500 pounds. Are you going to throw a pallet full of cinder blocks back there? It's the chassis that holds the weight - almost any engine can move it, albeit some slower than others.

that is not the diesel going into the trucks. One bad incident does not mean the whole line is junk. you had a lemon sorry for that, let each choose what they want in there truck.
The diesel is the one you see in the large isuzu delivery trucks or (tow trucks around here). I know nothing about it. Other than people in the diesel industry who use them for what they are meant for (not because they sound good) say it is a great engine that runs circles around others.
Yes the 6.5 sucks. To me it is just another option other than gas. GM has not been trying to compete in the diesel engine class, because they have had nothing to compete with.
Like before alot of the Dodge,Ford guys seem to be ripping GM apart before the product is even on the market. Saw it on the Silverado post now its happening here. What till the product is out, and you see what it actually does.
I question CAT putting a diesel in Dodge. Why would they back out of a deal with GM because the numbers are to low for them to build a whole new plant. Then all of a sudden sell it to dodge. Yes dodge may sell more diesel now but not enough to build a whole new plant. Sounds like rumor to me. Plus I see alot of posts of dodge owners having transmission problems. How could it all of a sudden handle a CAT engine. Besides CAT does huge diesel applications, and that is about it. My two cents on the CAT thing.

Listen up Kcram. Not every engine can carry a lot of weight. You obviously have no idea what you are talking. It is my opinion that you are making this up as you go. The chasis does carry the weight BUT it is the motor which moves it down the road. I am just trying to tell you that the 6.5 is not the weak engine you are making it out to be.

I see the emotipons are high--but if one of you could help me--I am looking at a 95 GMC 1500 witht he 6.5 turbo in it.
I really dont know jack about the motor but wish someone could help me decide if thsi is a "bad risk" diesel.
What has specifically been the shortcomings of it
What kind of fuel efficiency can I expect?
Should I just avoid the engine??
Please shoot straight with me

buy the cummins, last three times longer, you can only overhaul the 6.5 once, the cummins 3 times, that's probably gonna last you your whole lifee!

I can't tell you anything about the 6.5's fuel mileage, but I can tell you it has some big shortcomings. The 6.5 isn't even comparable to the Dodge or Ford in the power department. Another big problem with the 6.5s is the injector pump. They are notorious for going out and I've heard many stories of GM trucks with the 6.5 diesel being in the shop more than they are on the road. Definitely go with something else, I would be willing to trust either a Ford Powerstroke or a Dodge Cummins.

The GM 6.5 diesel is not a "weak" motor by any means. The main problem with it is the reliability of the injector pump, and the big bucks it costs to fix that.
If it weren't for that problem, it would be a fine choice.
Yes, I know about the numbers. Ford is at the top of the heap, with 500 ft/lbs of torque. Next is Dodge at 440 ft/lbs, then Chevy at 430 ft/lbs. But that's still plenty of power.
As for this business about Dodge putting a CAT under the hood... they better work on beefing up their trannys! They haven't been standing up very well to the torque the Cummins is putting out. How do they expect it to handle more? Maybe they'll put an industrial strength Allison tranny in it to handle all that power. Who knows?

If you're buying a 6.5 for a daily driver and almost always empty, the 6.5 may work out for you. If you're buying a work truck, maybe not.
If you're buying a used truck, do you KNOW how it was used previously? Has it always received DIESEL maintenance? Has the engine always been run with a fuel lubricity enhancer to lubricate the injection pump? What about cavitation damage in the cooling system? Are there WRITTEN maintenance records? There should be no real problem if the truck has been maintained properly. Is the dealer willing to give you a 2 year, 24K warranty on the engine? If the truck has been taken care of, the warranty is a safe bet for the dealer.
Now let me stir up some emotionalism!
I've always found that the cheapest vehicle to purchase is a new one. About the time the vehicle starts costing money to maintain, I get rid of it. (On the last two F-250s this was in the 120 to 130 K-Mile range.) The question that you have to answer for yourself is, when does this expensive maintenance life start on the vehicle you're considering. Finally, there usually isn't that much difference in the payments between new and used. Used are usually a higher interest rate for a shorter term.
Good luck with your decision,

they are right when they say it has problems with the injecter pump. you never know when it will go out.
It seems that some trucks replace them anually. An there are other trucks or suv's that have not had one problem.
WEIRD, My GUESS since they didn't keep it they have had problems. ONLY A GUESS. Safer to skip it

I had a 6.5 chevy k3500 that I traded on a '99 F350. The 7.3 is much stronger than the stock 6.5 Chevy hands down. If you are a Chevy man and want a diesel motor, contact Turbo Technologies in Tacoma, WA. They sold me an intercooler kit for mine that made it run away from any diesel or stock gas motor, empty that is. Put weight on it and it held its own up to about 10,000#. Add a steep grade and it fell off, not to mention the eventual high exhaust temp. For me there are currently only 2 choices on diesel pickups, Ford & Chevy, that is until Dodge comes out with a real 4 door.
