If it's under warranty do NOT use anything other than a Honda filter; I spoke to Honda USA and was told in no uncertain terms that they wouldn't honour the warranty if a Honda filter wasn't used! Any oil that complies to their spec is ok but do use an OE filter.Change oil...first service done...
Don't remove lower... use extension and wobbly in filter wrench and stock Honda filter/wrench... a little cleaner in the lower and she's done lickity split...
I did originally purchase a Fram and it didn't fit because of the header... too long.
Cheers...RR
