That's interesting that Redline cleaning up old wear could be the cause, I had no idea. Looks like the common recommendation is to retest but with a different type of oil. I've ordered an OEM filter and will swap in PP or something similar. I used to run redline in another car and I liked it. When I bought this one I changed the oil to redline. I believe the most recent PO was running mobile 1. 10w-30 is recommended spec for this car, 5w-40 if you're in cold climates.

Just wanted to add it could be a thrust bearing wear on manual transmission.
I have seen reports of S2000s going through rod bearings and even main bearings, but it's not that common and usually due to massive oil starvation, such as being 3 quarts down or extended cornering with r comps.
I'm going to put pulling the pan on the list and do it once I find someone who knows what they're looking for with the rod bearings. In the mean time I'm going to change the oil and filter. Regarding the thrust bearing, my wife drove the car while I was away at work for a week. I rode with her later and was cringing at how she was using the clutch, so perhaps that caused increased wear also.

very good point.

The car is basically stock with a conservative tune, I don't have an aftermarket oil pressure gauge, just a dummy light, which has never gone off and I've never had an issue with VTEC lagging, which reportedly happens when you have low oil.
