Nonsense. Expansion is no issue, you would not even notice it if you 
could measure the level on a dipstick. Anyway, the variety in the 
castings will give you more differences in volume than expansion. 
Filling to the level of the filler plug hole is recommended by 
practically every motor manufacturer of the day. This way it is certain 
that it is properly filled.
There is plenty of space filled with air above the filler plug hole if 
you are worried about expansion. Most of the time the filler plug hole 
is about halfway up the casting.
