Also getting a little startup rattle. So I am going to up the grade a little, maybe 5W-40 or even 10W-40.
I don't get your reasoning. You're getting some rattle on startup and that's probably when
your engine is cold (and any oil is thick). So it's rattling when your oil is thick, not too thin.
But for those who mentioned that 5-10W-40 is merely an increase in cold weather attributes,
let me remind you that all my oil analyses showed the original 0w-40 sheared down to a 30
weight rather quickly. So I think a more robust version 40 wt. would indeed be a benefit.
'Sheared down' or diluted down? It isn't the same. If dilution is your actual issue just do more
longer distance trips. Why trying to fight that with thicker oil when you perhaps could solve
that issue by adressing the cause?
