I can vouch for the safety of mixing OAT type coolants without consequence (both in my 986 and other vehicles).

I totally agree on the safety of mixing a different OAT coolant, but highly recommend that people know what they are putting in. There are still some coolants out there on the shelf that will turn the Porsche coolant into red Jello. One of the salvage cars I bought had that happen and the engine was trash.

I keep a jug of G12 (pink) around for the couple cars that still have Porsche or G12 in them. When I drain or flush, they get Zerex OAT or similar filling them back up.
