It still started out as a 30-wt. though!!!
Hondas run fine on 5W-30 year-round. This has been my experience. And i had one...
OP, you want a 20-wt. why?
You're missing the point.
A fundamental lubrication maxium is, "as light as possible, thick as necessary".
Even a 20wt oil is too viscous every time a car is started and remains so at least until normal high operating oil temp's are achieved.
So the OP is asking the correct question, is a 30wt oil necessary, and the answer is no.
