    This 1995 GMC Sierra 2500.


    It has the 6.5TD in it with 190,000.

    Main things I would like to know are:

    1. How are these 6.5's as terms of power and reliability?

    2. What would one of these average as far as fuel economy?

    Any help is greatly appreciated!

    Well I just got off the phone with her and turns out it runs really rough and it is only 2 wheel drive.

    But if anyone would still like to give some personal experiences or knowledge of the 6.5's I'm all ears.

    Its always confusing seeing a 3/4 ton with 6 lugs! :hammerhead: I personally wouldnt touch a 6.5L. Ive heard so many more horror stories than good stories. But theyre apparantly fuel efficient.

    I had a 6.5t

    Loved it when I had it

    It didn't have enough power to pull the hat of your head but it got 25 mpg

    Yeah that's why I'm not sure so I thought I would seek here for help. From what I have read some people absolutely love them. Then you have the other half that absolutely hate them and would never buy another one.

    But I do have to agree. I've done a decent amount of searching about diesels lately and of all the times I have read about a 6.5's...not one person complained about fuel economy.

    Yeah I have also heard this before too. I want to say that it was diesel place that did a test of the 6.5 vs the 454. While the 454 got to speed a lot quicker with identical gearing the 6.5 was way more efficient.

    What year was yours and is there a certain year to look for and a certain year to stay away from?

    Thanks for your input so far everyone!

    The 6.5 TURDO Diesel the only one that was okay was the first version with the mechanical injection pump. The ones with the electronic/mechanical pump was a nightmare.

    As for owning a 6.5 not for me I have driven them they are a gutless pig I would rather get poor mpg and own the 454 a reliable engine and cheap to fix.

    I owed a chevy 3500 with the 6.5 diesel for 5 years before I recently sold it. Very reliable for the 5 years i owned it untill the end. Started stalling.... hard starting when warm.... lot of white smoke at startup etc. After all the things I read that go wrong with these engines I decided to just sell it for what ever I could and move on. Bought it from a friend of mine in 2003 for $5500.00. Pulled trailers with it for 5 years and then sold it for $3,000. Not huge on power but pulled a loaded trailer quite well actually......

    My Dad's '96 6.5 is on injector pump #4, and computer #2, and it needs some kind of cooling fan on the ECU or it stalls on the highway or something.
    Other than that, incredible fuel economy, but the last time I pulled my tag trailer with my T190 it really struggled to get to highway speeds.
