	You might try to drop the pan and clean the oil pickup strainer, this  
can get clogged with sludge and gunk as the years roll by, or you might try
a lighter weight oil ( 10w-40 ) especially if you live in colder climes, heavieroil would be harder to get into the engine if it sits a while.  Do you drive the
car(s) regularly? if not try starting them at least once every two days, and
always be sure to let the car warm up before driving.
