Used Oil Analysis - High Tin levels

I'll post the next analysis in this thread over the next 3-6 months depending how much I drive it. Unlikely it will see the track due to COVID-19 restrictions. Current oil is HKS Super Oil 7.5w35 (4L) and 7.5w45 (0.6L) that I picked up on clearance. Threw in an archoil friction modifier as well. Filter was not changed due to the short interval, no doubt this will be another short interval to observe the wear numbers.
After this i'll be sticking to 40w exclusively for additional peace of mind.
I do feel however that either the elevated tin level is incorrect or insignificant due to the lack of metal in the vtec screen and the fact that the engine is running great... Who knows!

^^ Thinking thrust bearing failure?

Someone would need to confirm tin content in the thrust bearing, but yes.
It would be worth it to do the clutch interlock bypass, and see if the tin drops.
How long does the car sit dormant, typically?

The car sat dormant for a good 10-12 weeks over the covid-19 lockdowns here. During that time it was probably started (and driven) twice.
I do note that I pulled the fuse to the fuel pump and cranked the engine a few times to build oil pressure before I started; and even added a little oil before that too.

It does not have a clutch safety switch? I was not aware that any S2k (or any manual transmission car in decades) were produced without one. I assume a previous owner bypassed it maybe? Fine if they did, I was just surprised if it was like that from the factory.

Nice oil specs. I suspect you have been getting thrust bearing wear, but if numbers start to trend downwards and back to normal on the next oil change interval you might be fine if it was just a one time spike.

Maybe he did, who knows! I never press the clutch down to start it.
