You have flushed me out as well with your efforts (thanks for taking
the trouble to phone Rolls Royce) as I have been happily using
multigrade (oh dear) in my ferret since I bought it in 1987.
Oh $...!
So far no obvious problems. Which just goes to show, you can never
know it all.
By the way, how does someone in Southhampton have a Compuserve E-mail
address that reads as if it was American? I would have expected a
.UK at the end?
