Oil?

[Karl Robrock <robrock@domain.elided>]

I have a container that was given to me by the previous owner of my 164L,
containing Selenia 10W40 formula Alfa Romeo. The car was always fed this
oil. I was under the impression that 20W50 was to be used. Am I correct,
or should I use the 10W40?

Thanks
