FYI, the reason Honda Engineers want you to keep the factory oil in so long is because of the high moly count. Honda uses a moly coated piston ring for low friction and the higher moly count is suppose to keep them from scratching up the cylinder to badly during break in I guess...

Low friction, a key component to producing more power, is achieved through the application of Molybdenum Di-Sulfide (MoS2) piston coatings and cylinder sleeve plateau honing. Plateau honing lowers the friction level between the pistons and the cylinders by creating an ultra smooth surface. Plateau honing is a two stage machining process that uses two grinding processes instead of the more conventional single honing process. This also enhances the long-term wear characteristics of the engine. A low friction ion plated piston ring further reduces friction. In addition low viscosity oil (5W-20) is used to reduce friction.
