Ahhhh gotcha. I didn't see the 3 month 6 month ! My bad!
6 month 6,000km works just fine, especially if you take it to the highway occasionally. Unlike Engine temp, Oil takes 15km-20km to fully warm up and burn off any fuel dilution. 3 month OCI doesn't make much sense either, since a lot of people store their S2000s in the winter.
