Re: 7.3 Diesel Vs 5.8L Gas?
I have used all of the engines you mention. My dad has a 351 in his pickup. It has around 160000 miles on it and has done part time duty pulling trailers. It is pretty much gutless pulling heavy loads and his is about to give it up (excessive oil consumption). My first 7.3 (idi non turbo) had 250000 miles on it when I sold it and was still going good with more pulling power than the 351. I don't care for the 351 very much but am a believer in the engines in the newer ones such as the 5.4 and the V10. My mileage numbers would pretty much agree with the other poster with the diesel about 2 ahead of the gasser. Maintenance costs are definitely cheaper and easier on the gasser as the first 100000 miles just takes less than half the filter and oil money that the diesel does. If I was to buy one today, I would look at the 5.4 in a 99 for about the same money as a PSD in a 96 or 97. If you are looking at older ones, my personal choice there would be a diesel over the 351 but I like to do a little maintenance.
