Honda spec. 5W-20 oil in the USA and nowhere else. They sell the exact
same vehicle elsewhere where they spec. 5W-30 or 10W-30.

So, how critical to use 5W-20? Not.

I've been ignoring Honda's 5W-20 spec. and using Mobil 1 5W-30 (once
past a 10K mile break-in period). Cars are running fine. Just went to
Mobil 1 Extended Life (or whatever they call it) for my daughters' cars.
