I'm not starting a debate.  Heck, with you, I wouldn't have a snowball's chance!! 
;-)  Well, unless I was RIGHT!!  LOL!!

But remember a year ago or so I mentioned the Crown Vic getting 2 or 3 less mpg
overall when it had 10-30 in it rather than the recommended 5-30?  That happened
with two different oil changes, far apart in time. 

I agree, the oil should be the same viscosity when it is hot, but how do you explain
the difference in mpg?
