Yes, 5w30 is an option. The only problem with that is it’s has less detergents therefore the service intervals would have to be reduced. Let’s be honest.

Now that is the idiot salesman not doing his job! In your case, if you’ve done the the mds delete then you wouldn’t have to worry and could run 8-10k on 5w30.
