5/20 oil will not NOT cause any harm to the engine. Honda mechanics now in
most cases use 5/20 oil instead of 5/30 oil since the experts at the Honda
factory in Japan determined from their research that 5/20 oil works better
than 5/30 oil. I was told this by the service manager at the local Honda
dealership.
