Don't quite understand why people buy a new $40,000+ truck and then want to modify it, inject it with water, run unapproved, use bio-diesel and do other things on a truck with a warranty???

Why not buy a used truck with whatever mileage and modify it all you want. One it less expensive and two, you don't have to worry about fighting Ford over your warranty.

Personally, I would NOT run bio-diesel until it is widely available and has been approved. I'll wait for the diesel-electric motor like they use in locamotive engines if I want power and mileage. This could/would be the equivalant to the gas/electric cars from Toyota, Honda and others????

Thanks... just my .05 cents worth (which is more than others .02 cents)
