I have some one interested in my truck I have only had it for 5 months or so. I wouldn't mind selling it anyhow I may go back to a IDI truck the PSD is a frigging fuel pig or that truck is. I was told the PSD powered F-Superduty trucks are hard on fuel but I didn't think it would be that bad. I have been doing allot of driving lately putting on about 220 kilometers (136 miles) every 3 days and its costing me anywhere from 40-50 dollars I also found out something today that is bugging me and it confirmed something. I have thought I seen this truck I bought before I couldn't place it then I did a free VIN check it said auction sale. Bingo now I remember the truck was a tow truck some one took the tow body off and installed a flatdeck. I actually looked at the truck when it was at the auction it had engine problems it ran like a bag of crap so that is why a used engine was installed by the dealer I bought the truck from they said rebuilt its no rebuild. The transmission in the truck isn't too long for this world either now that I realized this truck was a tow truck then its seen some abuse plus someone had the wrong oil in it so when the truck is in 5th gear doing highway speed the stick shakes back and forth. It does have a new single mass flywheel and clutch installed. I do have my eye on another F-Superduty PSD ya I might be stupid to look at it but the truck has 55,000kms less than mine its a 97 it is a XL where as my 95 is a loaded XLT. I still have my mind on a F-350 4x4 and I can run a 11' dumping flat I won't have the payload capacity but I'am not going to haul sand and gravel. I mostly use the truck to carry tools etc and haul trash. One of my main question I know I have asked this before but would a F-350 see any better mileage with 4:10s the truck I have now has 4:63. The 12 mpg is hard on the wallet its still better than a 460 gas 6 mpg. I thought the IDI was a little piggy on fuel the PSD is worse. I think I may go for it and sell the truck I have someone nibbling at the bait might aswell sink the hook and seal the deal. What do you guys think is a PSD F-350 going to do better in the mileage department ?
