    Just wondering how the engine holds up and what kind of mileage you are getting out of it?

    I am tired of making the monthly payments on my 2001 Jetta and need someting that is half way decent on fuel. Thanks.

    I have a 6.2 in my 83 1/ ton. They are tough motors as long as you follow a strict maintenence program. I get between 18-26 MPG depending on how I drive and whether I;m towing or not.

    You should spend a little time in the Diesel Forum here. There should be a lot of answers to any questions you may have.

    I've got one, and I check the Diesel forum on this site regularly.

    I get around 18-20mpg in town, max of 27mpg on the highway. Specs of the truck are in my signature.

    Great trucks with great engines.

    I have an '82 that supposedly has the most problems of all just cuz it was the first year of production but mine runs great, I do not have to be really strict about the maintenance on it. I do check and change filters, when i feel the need but not every 3000. I go about 6000 before an oil and oil filter change, and I change the fuel filters, well i have had the blazer about 4 years and have changed them twice. The guy I bought it from is a very good mechanic and he told me when he had been changing fluids and I figured if he kept it running that long I will continue what he started. Some of it may have to do with me being in central texas with no real temperature extremes except heat in summers. sorry so long

    I Had one, it was a turd. Did get ~20 mpg when I bought it, best was 27 w/35s. Was down to 14 mpg when I swapped in a TBI 350. Much better now. IMO NA diesels suck.

    I need something as a daily driver, no off road at all, so I do not care if it is a turd. I just need something good on fuel and reliable. thanks.

    Mine had enough power off road, it was on-road that suffered. One good thing about them is that they are injected and don't suffer from the same off-camber problems as carbs. If your just looking for a driver, not planning a lift, big tires, or towing, I guess you'd be ok. I suspect altitude would make a big difference in a NA diesel, I've never driven a 6.2 at sea level, but I know my turbo Cummins hauls in the mountains. (I guess the 35 psi of boost may have something to do with that.)
