5w20 would be the same with either standard or synthetic?
New engine, though.
With older cars (200k miles), don't parts wear out, needing a thicker oil to fill larger gaps? Like a plain 30w, or a 10w40?
On previous cars I just put 30w in summer, then change to 10w30 in the winter.
What would someone who knows what they're doing, do?
