Hi,

You'll be just fine. No need to contact Porsche or PCA. Keep topping up the tank to further dilute it for the next couple of weeks. Your DME may detect it and switch to a different fuel/spark MAP for the duration of the time the stuff is still in the system in any quantity and you may notice a variation in performance, but probably not. The Glycol could trigger an O² code, but I bet it doesn't in such small quantity.

The amount you added is very small and probably less than some people get in their systems from the underground gasoline storage tanks. Moisture enters the system constantly as moist air fills the vacuum in the tank as the fuel is consumed and condenses to water. The engine can tolerate a fair amount of it relatively speaking.

Since it's heavier than the fuel, it will settle to the bottom of the tank. Keep it topped off for a few weeks and then run the tank near empty to rid yourself of the last of it. Nothing to panic about, especially to the point of dismantling the fuel system. Gasoline also contains drying agents which will also help in ridding it from the system. Hope this helps...

Happy Motoring!... Jim'99
