What kind of fuel mileage should I expect
im looking at a 2000 FLD 120. it has a 12.7L 430 1650 torq with a 10 speed and 3.73 rear ends and low pro 24.5 tires. what should i expect for fuel mileage? the tires are recap firestone tires (not liking that part of the recaps on the drives i think its stupid) the truck has 1.182 million on it the dealer is getting the history of the truck for me so i can find out what has and hasnt been done to it and he is going to run a ECM report and im going to do a rig dig report and oil sample the motor. he started it for me today and everything sounded good ran right around 750 rpm at a ideal. the computer doesnt work in the truck thats one this i first things i noticed but even if it work should i trust it or trust the ECM report? hes asking 16500 im thinking 15k or less depending on what hasnt been done to it. cause i can buy a 05 or a 06 with a 445 detroit 10 speed and 2.64 rear ends with 650k for 22k so is asking to much?
Is this a worthwhile discussion?
