Why should I wait to change the oil the first time?

Your Honda engine was delivered with an oil that is specially
formulated for new engines that have not yet developed their "natural"
wear patterns and may contain minute particles from the manufacturing
process. American Honda strongly recommends this special oil be left
in the engine long enough for these wear patterns to develop, usually
until the first maintenance interval specified in your Owner's Manual,
based on your specific driving conditions.
