7.3 IDI Fuel Mileage?

I just bought a '93 f-250 with the 7.3 IDI. It has an automatic tranny, and 129k. Was wondering what kinda mileage i should expect to get. Ive heard everything from 14 to 22 mpg highway. I intend on driving as efficiently as possible and usually without a load. Also, is there anything relatively simple i can do to this truck to achieve better mpg? I dont know a whole lot about diesels as this is my first. Any help would be majorly appreciated. Thanks, Jake.

Is it turboed? If so it'll get better mileage then if it doesn't. If not, I would guess around 16-18 mpg, with a snail, closer to the 20 mark, if not over.
