I always wondered what LMA stood for! However, as LMA IS soluble in water-
and therefor presumably can contain small amounts of water- and I don't
think Silicone fluid is water soluble, my original reasoning stands. I am
actually relieved that LMA doesn't absorb much water however! My scenario
involved relatively small amounts of water total (< or = 1 mL) in the
system.
I agree that whatever the fluid is, it should be changed every so often.
I am told that new vehicles now come with silicone fluid in sealed systems
that supposedly NEVER need fluid replacement under normal conditions!
So Casterol LMA acts very much like
