    My 94 chevy 3500 dump (diesel) is getting very bad fuel mileage. It is a 6.5 turbo with a 5 speed. It is useing twice the fuel as my 94 ford 7.3 turbo diesil. Are these things known for fuel consumptiom?

    What kind of milage are you getting? Is there black smoke on acceleration? How many miles? How long since last injector pump? Rear Gears? Fuel tank leak? (just kidding) Take $15.95 of the money that you will spend diagnosing this and become a member to http://www.thedieselpage.com its well worth it.

    Good Luck
