Oil Analysis
I had an oil analysis done a while ago by Blackstone Labs. Just sharing the data. I'll add more as they become available.
Note -- this oil was whatever the dealer added at the prior maintenance. As you can see it didn't maintain 10w-30 properties (if that was even what was used) over the 5,500 mile period. This oil change was done with 5% oil life indicated on my 2006 MY.

From the other F22C1 UOA's that I've seen, this looks OK. I think Honda put some of their bulk 5W20 oil in there though. I don't know why Blackstone said 5W30. If you are concerned about oil viscosity used in your S2000, make sure to specify which you prefer to the service manager. Otherwise, I bet the quick lube tech will continue to fill with 5W20. Did they put the correct oil filter on?

Thanks for posting the UOA
Ask your dealer what oil they DID put in, as INDYMAC mentioned it most likely was a 5W-20.
Your UOA shows that's OK, no need to change anything as long as your driving style doesn't change (suddenly going to track days every weekend, Autobahn kinda long high speed runs etc.)
If the dealer confirms it was a 5W-20, keep doing what you're doing, its working perfectly.
If they say it was a 10W-30 you may want to stop using it as that brand & type of oil shears down a lot and you're not getting what you pay for.
How was this sample taken?
There is a little fuel dilution
Ask Blackstone to do a TBN as well next time (will cost $) to see how much "Oil life" is left after 5500 miles.
Knowing wear metals, viscosity, fuel, water etc is IMO 1 of 2, knowing the TBN, Total Base Number, is handy to determine if the oil was still able to deal with acidic combustion by-products every internal combustion engine produces.
If the TBN gets below 2 or 3 (according to BITOG IIRC) it may be better to shorten the OCI a bit or use better oil.
And yes, ask if the dealer used the proper oil filter.
The S2000 uses a specific, non-Honda-generic oil filter.
Part # 15400-PCX-004, check the FAQ on top of UTH for oil filter threads.

Sounds like a great plan bat711. Posting a UOA of Mobil 1 10W30 would be of great value to the forum. It seems to be the most popular choice here and many people swear by it (or was that swear at it?). Anyways, you will be the first to post a UOA of M1 in the S2000 that I have seen. Thank you very much!

That UOA looks pretty good. Compare with mine in the second link below.
First to post data on Mobil 1 Oil? Not by a long shot!
Scroll down for commentary on Mobil 1 oil.
More recent issues with elevated copper levels.

I agree, this is a good UOA. Thanks for posting.
I'd be inclined to think they used a lower viscosity oil on your previous oil change since this engine isn't prone to shear oil, and your wear is low. They definitely did not use Mobil 1.
I agree with SpitfireS - testing for TBN tells a lot about how long you can go on the oil used.
