[ProjectM96]

I called Porsche of North America and asked them about the gas when I bought the car 2 years ago.

They said that 91 is the minimum accepted octane because the engine would be prone to knocking, but they recommended 93 octane for best performance.

Also, I live in Philadelphia. Last week, some gas stations in Philly and Warminster, PA started running out of gas. One Sunoco gas station had nothing but 100 octane race fuel for $8.99/gallon. No more regular, midgrade, or premium fuel. I drove around to another couple of gas stations until I found a pump with gas.

Then I drove to Newark, NJ airport since I was traveling to Michigan. When I got on the NJ Turnpike, I saw a pick up truck. The back was filled with red gas tanks AND he was towing a trailer filled with gas tanks, which is illegal. I read online that people are selling gas on craigslist for as much as $30/gallon in NJ.
