For our summer-only Z, this will be at the end of the last ride of the driving season with regular-service Mobil 1.

Thanks again.

I encourage you to send off samples of your oil after each change to Blackstone Labs. It only costs $25 and they'll even send you free materials to ship the oil. They will give you straight up facts about the quality of your oil and the amount of contaminants.

I hate quoting myself, but I already conceded defeat on the two-year interval in my post #13 earlier in this thread:

You said you've done two year OCIs in all your previous cars. I still question what makes you think that a two year interval is ok. It is very likely that your other car manufacturers recommend 6 month minimum OCI just like Nissan. I bet its not 2 years

Also, I read your logic for 1 year oil changes ... Go read the Bob The Oil Guy forums and you'll quickly realize it's far more complicated than your explanation. FWIW, I have seen manufacturer recommended 12,500mile/1year OCIs recommended on some vehicles in recent years, but they were not high performance sports cars.
