Honda's factory fill oil is a special blend, probably made for them by a brand name company but specially blended to add a ton of moly. There have been several VOA's on this oil, it is clearly a special blend.
Even their bottled Honda oil has been tested to contain high amounts of moly.
I don't know about Audi, but Honda's been doing this special factory fill for many years.
I personally have changed mine out at 1000 miles, I like to get the metal filings out. I think Honda tells people to go a certain amount of miles so that they can get standardized information about how their vehicles wear. Having the majority of their vehicles break in the same manner probably helps them monitor wear problems over time. Also there is a huge push within the industry to keep operating costs in the first 2-3 years as low as possible. This is a big mareketing ploy to help sales if you can tell your customer that the first 2-3 years of operating costs are lower on your vehicle compared to the competition's. And vice versa, if your costs are higher that may hurt sales. All consumer testing auto mags list operating costs for vehicles on long term tests. I think it's useless info but it must attract some people.
