The car was bought late dec 2002 so no luck with warranty.
Call Honda Canada regardless. Say you are going to log a complaint to Transport Canada if they blow you off right away. You never know their policy on this particular model when they know there are problems.
I would not sweet this oil thing. just keep adding and don't bother with oil changes other than the filter. It's a minor inconvenience, but not worth throwing money at. From May 1st to October 31, I'd run 20W50. Winter, you're stuck with 10W30.
