    I have heard lots of information on this forum regarding Ford Powerstrokes and Dodge Cummins diesels. Have any of you guys had experience with the diesels in GM's 2500 and 3500 pickups? Fleet Force has had a few 1995 - 1999 models lately and I was curious about the quality of these engines.

    1995 3500 dually. Fuel injector pump,(2) $1700 for first, second was warranty, fuel pumps (2) $50each, clutch, (2) $800 each time, second clutch was because the mechanic put the wrong one in the first time. All this was last year, owned truck for 5 years and the first money had to spend on it. Other wise, a perfect truck. Truck has 150,000 miles.

    I have the new 6.6 Duramax and it is AWESOME. This is the first diesel I have owned and wil never go back. The 6.5 is a good engine and holds it own.

    Go with the Duramax..stay away from the 6.5L. We had two and they went through injector pumps like a fat man through potatoe chips.

    That sounds great. What kind of gas mileage do you guys get with and without hauling equipment?

    Without a load an average of 18 mpg and with a full load average 16 mpg. Not bad for a Crew Cab 2500 4x4 with 35" tires.

    '97 3500 crew cab lwb that I have replaced the injector pump two times. 1st at 125k second at 130k(under warranty). 17mpg hwy no load 14 around town w/3500# load. Bought the truck @ 97k 2 years ago. Also replaced alternator, batteries, & a/c comp. When the injector goes, it takes a long time to fix( truck out of commission for over 2 weeks combined to repair right).

    We have a 94 3500 with a 6.5, it has 240,000 miles on it and runs great. The only thing I have done to it is change fluids and put two alternators in it. We work it hard every day and it just keeps on trucking

    Don't do it! I use to haul cattle and started with a '95 chevy 2500 with the 6.5 dog in it. I would put on about 120,000 miles a year. I kept the Chevy uptil around 175,000. Pretty much everything major had been replaced by that time. Engine, tranny, rearend, you name it, it was replaced. Bought a Ford with powerstroke in '97 and wouldn't buy anything else. I've had: '97 F250 215,000 miles, '99 F250 285,000 miles, '01 F250 280,000 miles '03 F350 with the 6.0 120,000 miles. Only major repair on a ford was a tranny in the '01 at 227,000 miles.

    but i still like my PSD (power stroke diesel)
    its a 99 and i havent realy done anything except fluid changes, and washing it..

    and i beat the H*LL out of it ...

    (im not a big fan of the duramax myself but it IS A GOOD TRUCK too.)
    (for the people with PSD's i would put a chip in it/reprogram it & put a 4 1/2 inch ext. pipe from the turbo back, you will see a big diff.)
