A sister site to this one The Diesel Stop would be a good place to ask that question. That site is focused on Ford diesels.

1990 and newer is a HUGE margin. In that time there were several diesels. The most popular and maintenance friendly was the 7.3L powerstroke V8. The later 6.0 unit was unreliable and had a short shelf life at Ford (replaced with the new 6.4L). The 6.0L unit didn't get much better mileage than the 7.3L. If you plan to tow regularly then a low mileage 7.3L would be your best option. For everyday driving, again I recommend the 7.3L, but the 6.0 might be more appropriate for ever so slightly better mileage. The diesels I drove years ago (98' 7.3L) got on average 14mpg towing 6.5K and around 15-16mpg average not towing and with a light foot.

My '04 Freightliner Columbia had the cheesy 12.7L MB 9000 engine and averaged 8.1mpg during my eight months with it. Worst month that I had (January) I averaged 7.15mpg. Not bad - but I'd much rather have a Detroit to pull 46K of cement from Ontario to NC!
