My 2003 HX coupe (CVT trans.) calls for 5W-20 motor oil. It says so in the
owners' manual and there's a sticker right on the engine block that says
"5W-20".

I'm due for an oil change but none of the places around me have 5W-20 --
they all tell me just to use 5W-30 (which is all anybody around here seems
to stock).

Q: Why does the HX coupe w/CVT call for 5W-20 (instead of a more "common"
weight) ?

Q: If I use 5W-30 (instead of 5W-20), what are the consequences?
