I am not a huge fan of 10K OCI, they can be done but you need a really good filter and UOA and the average sure doesn't think about either of these things. Plus if you run 10K OCI you need to keep an eye on the oil level and I bet mostly people hardly ever open their hood between oil changes unless they are maintenance freaks like us here on BITOG.
Toyota, for the Corolla's anyway, went from from 10K to 5K and then back to 10K again, after they got past their clogging low tension piston ring issues. So the huge jump was tested before, at least as far as filters were concerned. Maybe not so much for rings.
But yes for older cars, 10K is a long way to go on a 4 quart sump. Caddies and Vettes and other vehicles with long synthetic era OCI's have bigger sumps. If I didn't check the oil sometimes I wouldn't have caught the Honda Pilot before the CEL/low oil warning would have come on. It turned out to be a clogged PCV valve, but low oil is low oil. But then again, when do manufacturers care about post-warranty maintenance issues?
