Definitely don't use 15w50, that means the oil is thicker when cold (the last thing you want on an S65!), and thinner when hot.
If you're going to for a different grade oil a 5w-50 would be a better compromise, at least it's thinner when cold. Although there was some disadvantage with that grade oil, I can't remember for sure but I think it was that it shears down quicker?? Anyone recall?
