I have seen a lot of D16Y8 have over heating issues, and eventual HG failure when they are not looked at properly.
Make sure you re-fresh your coolant as time can be a factor as well, fan relays, radiators, and hoses can be problematic.
But the engine doesn't care about oil, use whatever certified motor oil you want.
