Did something stupid, please advise

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

Your post reminds me of the time I accidentally washed my windows using a bottle of tire-magic spray-on shine.

Not recommended.

Ah ha! There is someone else! I thought I was the only one who'd ever done that!

Thank you so much for the advices. I top the gas tank with new gasoline to dilute it and will do a couple more in the next few weeks. No more working in the dark for me

I know this is a very old thread...but I feel like I need to update this.

If you ever ever put a coolant additive (such as redline) into the gas tank like me (wonder if there is anybody else that idiot), no matter how small the quantity is, it is best to suck the gasoline out and clean the gas tank.

9 months after this incident, my boxs had engine problem with the cylinder stopped firing (I posted the problems if anyone ever noticed). The porche mechanic checked (basically opened up the engine to check if the piston cracked or something) and in the end, it turned out that the fuel line to the cylinder got stucked because of the 'red jelly stuff' that clogged the fuel line. They also found that the 'red jelly stuff' was stucked inside the wall of the gas tank. After they cleaned out all of the 'red jelly stuff' out by flushing the fuel line and gas tank, the boxs runs like a champ again.

I requested to have this 'red jelly stuff' analyzed with a 3rd party lab. The lab tech told us that the 'red jelly stuff' is most likely a coolant additive. Please note that I've never ever mentioned to the Porche mechanic that I put a coolant additive inside the gas tank 9 months ago (who would have guessed as it could have been dirty fuel). About $3000 including labor spent for the fix...lesson learnt.
