Thanks in advance for helping a rookie.

I dumped the break-in oil right away because my build date was almost a year from the date I took delivery. MBUSA recommended that I do it, and they contacted the dealer and they did it for free.
I also did an oil analysis ($22.50) and it showed fuel dilution, water in oil, and the TBN additives had dropped. Any car sitting on a dealer's lot doesn't get driven enough and when it does, it's only for a very short time to move it around the lot. That's not good.
I say change it now. Then do it every 7.5k. Each time do an analysis. If it looks good for the next two changes, then you can stretch the intervals. OCIs are based on driving habits and environment. The MB recommendation of 10k is a generalization. If you live in a sand blown desert and drive it as a taxi, or track it, etc., you need to adjust the OCI accordingly.
