Older Ford F-350 question by gmacy

I have a '97 Ford F-350 pickup, 4x4 with a 5.8 v8 auto trans. The truck only has 54,000 miles on it and it in good shape. Does anyone know if I can do anything with the gas mileage? I average betweem 7 and 9 mpg all the time. The truck will pull a house with the 4.10 gears. I've done a k&n filet, 3" exhaust, synthetic fluids all the way around.
 
Any one have any other ideas? Thank you in advance.

f-250 super duty by bruce74

I have a 1999 f-250 super duty, 7.3, that gets about 17mpg around town when I'm not towing. I pull a 5000lb camper, pull behind, with a 700 lb motorcycle in the bed, and then the mpg drops to 11mpg. I bought the truck used, so I don't know that much about it, Its got about 170,000 miles on it. Anybody know what could cause that much drop in mpg. My little f-150 towed the same camper and got 10.3 mpg.

Try checking your tongue weight. Instead of towing the weight you may be carrying the weight.Carrying instead of pulling the weight can cause a huge drop in economy.The same wil hold true if you have a fifth wheel trailer.

Okay geniueses.The question of the day is if you can drop the engine RPM by 100,200,300 how much econo change can you expect to get.This may be possible and still maintain 70 MPH,on the big road.Have a couple of ideas, that I am pretty sure can achieve the RPM drop.Does anyone know how much difference the drop will make?
