As a rather old fashioned person I have always used 20/50 oil in my cars but as a member of a classic jaguar forum I asked about engine protection for cars that are not used very often, a member who has worked In the oil industry all his life has said to move to a fully synthetic oil to Mercedes spec 229.5, so do members have other opinions.
