Additive
Has anyone caved in and used gasoline additive to counter the 10-15% ethanol in the gasoline that the Porsche cannot tolerate? If so, with what results?

In the US, the max is 10%. Not talking about E85.
Gas up with a national brand, from a busy high volume station, 91 or 93 octane and be done with it.
Prior to your oil change, run a tank of fuel treated with Chevron Fuel System Cleaner with Techron.
For long term storage, winter hibernation, use 1 ounce StaBil per 2.5 gallons fuel.

I'm just wondering about "cannot tolerate." Sure there are problems with ethanol deteriorating some parts in the fuel systems of older cars. But everything Porsche makes has for years now been engineered for ethanol. Don't get me wrong- I know its crap, with lower fuel energy density, moisture problems, and just generally awful for engines compared to gas, to say nothing of the environmental and tax (oops! P&C content?) catastrophe of growing corn… never mind. Its crap. But "cannot tolerate"? Its been designed to tolerate crap just fine.
So avoid ethanol if you can, but if you can't, why worry?
