93, based on absolutely no empirical evidence whatsoever.
I'd be curious to know what octane the timing advance is based on for these cars.

I use premium as well, and I know the 16V requires a higher octane rating than the 8V's.
Just wanted to see what the consensus was. Thanks! |

Our engine mangement system has knock sensing so if lower octane gas in put in such as 89 or less (Porsche says 91 i think), then the motor will "retard: timing slightly so engine doesn't knock. Driving around town isnt a big deal, but at 10.9:1 compression, under load, or high RPM, the engine may feel a bit sluggish.
Put the good stuff, go with min octane rating 91 or better.

Premium. These cars have high compression (10.9:1). However, you can use a lower octane gas and the knock sensor should compensate by retarding the timing with some power loss.

My understanding is that you are supposed to use premium so thats what I use. 87 is fine for long trips etc. as the anti knock sensor will kick in. |

premium too. 91 is hard to find so 93.
I can't believe you guys can get 30~35 mpg. I get like 23mpg, all hwy, and I think everything is tip top.

i run 93 in mine and its chipped....i don't run anything lower because of the chip.
is anyone running a different chip in theirs? i believe mines from lindsey.....and as for mileage, I get about 23 city, and 28max highway. Is the chip to blame?
