I drive a company F V10 and GM 8.1 daily. The v10 gets almost double the mpg of any of the 8.1s I've used and has plenty of power. I'm not a F guy but the F's aren't in the shop as much as the GMs. I have/had 2 terrific CTDs. 97-98.4 was the best 12 valve CTDs - bulletproof fuel system/no emissions/great mpg. 98.5-2002 was the 24v but the fuel pumps were somewhat problems but not all of them. 4w disc brakes came in 2001.5. 03 was the first common rail fueling and the lift pumps can be weak. 03-04.4 had no emissions/great mpg. The 7.3 6 spd trucks I know of are very good trucks but not the autos. You have to keep up on the 7.3 glow plugs/control. A friends 7.3 wouldn't even start on a 50 degree morning when his glow plugs didn't work. Don't go older than about 98 7.3 - no inter cooler. Craig
I'm calling you out on the 2valve V10 getting twice the mpg of an 8.1L. All things being equal, the 8.1 has more hp, more torque, and better fuel economy while towing. And if one keeps one's foot out of it, better non-towing mpg. Now, GM stopped production of the 8.1 for 2007. Ford continues to use the v10.
