7.3 Acceleration

Unfortunately I am new to diesels and are unfamiliar with how they should drive. I just bought a 2000 model F250 crew cab 4x4 and wonder if it is performing correctly. It may be just that the truck is so heavy, but I've owned a 4.6L F150 gas burner for years and it seems to have much more acceleration power. In the diesel, you have to really step down on the pedal to get it up to 70 MPH w/o taking up to 20 seconds. Is this normal? Also, it only got about 13.5 MPG after first fillup that I've had it, which seems quite low considering it was unloaded, not towing, and highway miles. Is this typical mileage? I bought it because I figured it would have more power and get about the same if not better mileage than the 4.6L towing.

How well was the vehicle maintained before you bought it. You might want to check the filters air and fuel for starters.

It is not rare to find one that is kind of a dog, especially unchipped, but what you are describing sounds like it might be something else.

I don't have any of the service records, but I assume it was well maintained on sure fact that the truck was so clean. It does have 245,000 miles, but the engine is very clean without any oil leaks whatsoever. The oil has been changed 2000 miles ago according to the sticker. The air filter looks fine although I'm going to change it anyways and check out the fuel filter.

Don't forget the truck also weighs around 8,000 pounds,thats a tad bit heavier than the f150 you had.
