Recent loss of fuel mileage

I have a '99 F350 7.3 diesel. I went from getting 400-430 miles per tank of fuel to less than 300. Is there anything I should look for, EGR valve, etc? This happened all of a sudden. Found no leaks and not driving (towing) differently, no recent changes.

Hey I just lost some milage in my truck too but I think it really is the winter blend fuel that was replaced up here in the northeast. Cuz around this time of year I go down in fuel milage but not that drastic around probably 1 mpg less.

same here, but about 330 MPH a tank on a LB.

i'd check the brakes, ball joints, steering, wheel bearing, filters stuff like that it all has a role in MPG

My mileage dropped a couple of miles per gallon also. Also seems a little down on power when towing. I was thinking it might be the fuel.
