I checked my fuel mileage today I did some real light hauling some furniture then a couple days ago some scrap aluminum. I was kinda disapointed to see 9.5 mpg I will check it again next time I fill up . What I have been told is becoming true these 95-97 F-450s with the PSD are pigs on fuel and the guys that own 6.0 F-450s are having the same complaint. If I'am only getting 9.5 mpg with light loads what I'am I going to get with a full max gvw load which I havent had yet if it drops below 9 mpg its gonna be expensive to run this truck My 89 F-450 IDI would get 11 mpg loaded it really didn't matter if it was 2000lbs to 7000lbs the truck got 12.5-13 mpg unloaded. I hope I didn't make a mistake and buying a PSD Is this normal for a F-Superduty (F-450) with PSD power to get bad mileage geez 9.5 mpg thats disgusting I had a 88 F-Superduty with 460 power would get 8mpg and the that truck weighed 8300lbs the 95 weighs 8400. The 460 was bad it would eat up 1/2 the profits in fuel hauling sand and gravel and that was 3.5-4 years ago when regular gas was considered cheap. The 460 liked the fuel when the truck was grossing 16,000lbs you could litterally watch the needle drop the engine screamed feed me I'am thinking about going to a 1 ton again and put a 11x8 dumping flatdeck on it if it will net me better fuel mileage and I mean better something like 14 mpg empty and 12mpg loaded. If a 350 won't net me better mileage then I will just suffer with my current trucks bad fuel mileage I will just have to squeeze the customer for more money if they squeal tough tar paper. What do you think should I raise my trucking rate to 60 dollars per hour I'am currently 50 dollars per hour I may even make a minimum chage 100 dollars for a hauling job plus labour if involved. I currently paying $4.15 per US gallon for diesel fuel.
