There's a rocker switch for the OIL DILUTION SYSTEM. On my C model it is just to the left of the beacon/nav switch. I never had the system but the panel is labeled for oil dilution. There is a little info in the POH but have never found anything else in the SM. Maybe one of the fuel schematics might call out the system.
