Interesting to note that Porsche extended the flush/replace interval with the late GTS cars OEM's with that fluid. They go on to say that it's ok to retrofit the earlier cars with the newer fluid, but you must maintain the original cahnge intervals even with the new fluid. The wet boiling point isn't significantly better than a premium DOT-4, so it must have less affinity for moisture than the DOT-4's.
