I agree that you should go with whatever the manual says and disregard anyone who tries to overrule (in this forum or anywhere else) what the manufacturer says to do. However, as noted above, the manual for new Ford V10s says to use 5W20. The relevant page from the manual is attached http://www.skiprd.com/OilCapacity.pdf. Yours may be different and definitely go with the manual, but double-check to be sure.
