Given the gearing and RPM's that engine is running daily i don't see any issue with it vaporizing/burning of a qt every 1500 miles. that is the nature of running a big gas engine hard constantly. It will not matter if you use 5w20 or 5w30 in and application like this were the engine is cranked up to 4k rpms nearly constantly and under load, the engine is going to consume some oil. Use a good synthetic or motorcraft syn-blend because of the extreme conditions it runs under and stick with the 5w20 as per the engines spec. just keep a couple quarts in the truck to top off with periodically.
In my opinion this isn't a case of the v10 is junk or ford is at fault, rather a pure fact that this engine is being ran hard all the time. if it was a vortec or a hemi it would use oil too under these conditions, these are simply brutal conditions for a N/A gas engine. Keep oil in it and it will stay happy.
I would agree with this statement. If the v10 has an oil cooler I doubt very much the oil is getting to hot to affect film strength.
Give it 10000 miles. I'll bet the consumption a will slow if not cease
