After you put the STABIL in a full tank, run it around the block to get it inside the engine.

Overfill the tires to MAX pressure listed on the sidewall, per the Porsche Owners Manual. Leave your self a note about this in the car for the Spring.

I also leave my trunk 'popped', along with the battery maintainer hooked up, just in case the battery dies from a power outage or otherwise.
Not fun trying to get into your trunk to charge/change a dead battery when the 'frunk' is locked shut.

After all is said and done, that baby should fire right back up when you're ready. Been doing it for years!
