Ouch. I would cut your OCI in half for sure, and probably do the reccomendation above. Are you in Canada? Is the car a DD and driven in winter?

I run a Redline blend and get great oil reports (posted above). I just got another one last month but I didn't bother to post it as I only did 382 miles in the past 18 months.. I def need to drive the car more, Doh!

Yes I plan to change it more frequently. It looks like the previous owner (based on the service records I have) did an annual oil change with 0w-40 and he daily drove it which ranged from 8-10k kms between changes. When I bought the car it had already been a year since the last oil change so I did changed it immediately and sent that sample off Blackstone which is what you see here. Does not look like it was winter driven, though (southern Ontario) since the underneath looks quite clean and no signs of salt or corrosion anywhere. My previous 997.2 Carrera had great reports so I'm a bit shocked to see these higher metals appearing in the sample. Is it something I need to look at immediately or is it still low enough that I can just monitor and test another sample in couple thousand kms?

Figured I should add mine, just to contribute to the growing info they provide.
