I have heard and had personal experience when changing over to MOBIL1 in
an engine that was origionally run on dino that after a while it leaks.
There is something missing in the oil to swell the gaskets, or
something like that. Not that I don't swear by MOBIL 1, My engines
seem to last forever on the stuff and I love it. I wish I could get it
to stop leaking though. Anybody else hear of this?

You should have no issues at all, but I would get an extra oil filter
and change it 1000 miles after putting the Mobil 1 in -- a huge amount
of sludge will come loose if it's been run on dino oil, and this will
clog the filter pretty fast.
While I agree that Mobil 1 will dissolve much/most sludge, - the
operative word is DISSOLVE - and my opinion is that the need to change
the oil/filter before the factory suggested interval would rarely be
necessary. I've change over many high mileage diesel engines to M-1 and
there was NEVER any evidence of anything close to filter occlusion.
Still, the filter change will certainly hurt NOTHING.
