I think the general idea in this is that the thinner oil will seap
thru seals and gaskets that are aging. It's the same principle of
why you don't use synthetic oil on old cars. It's so slick that it
will leak in almost every seal. Another thing is the piston rings
that might not scrape the oil from the cylinder walls.
