I use the Motorcraft 5W-20 semi. After 4000 miles it gets close, but never below the low mark. I would always use the exact 6 quarts Ford recommends and not over or under fill. The dipstick should be used only to make sure the oil level is acceptable, not as an exact fill point.

I'm with you krewat and neilc88. Call it a hint or a tip: Never overfill or under-fill the crankcase.
Too much oil and the crank will splash around in it causing a loss of power and at worst it will get into places it shouldn't and start leaking or damage the engine and too little oil will cause premature wear.
Krewat,
Remember the old saying that you if fed an old diesel ether every morning to crank it, then eventually it would get hooked on the stuff? As illogical as that may sound it happened. Same could go for those engines that constantly had to “burn off” excessive oil. Hmm…

One reason Ford has the 6qts-only rule may be that oil (like tranny fluid) expands when it gets hot. They are covering all bases, when hot, 6 qts might show pretty high on the stick, if you let it set long enough to drain back to the pan. Cold, I'm sure it'll show lower.
I actually haven't heard that about ether, but yeah, I can see that. Ether and diesels don't mix (except high-hour motors that won't start otherwise). I would think gasoline or something else could be used without blowing the ring lands
But, I don't think too much oil consumption from overfilling will cause consumption later on. Ether and diesels, yeah, you are putting the peak combustion chamber pressure way too high, and causing damage.
Is it better to have oil above the rings getting burned turning to soot (abrasive) or better to have oil above the rings so the cylinder is lubricated better? Or better to have the oil wiped off each time, and the compression rings are less lubricated on the upswing?
