93 Octane in a 997S
My local gas station here in California just started selling 93 Octane gasoline. What do you guys think, should I be filling up with it versus the standard super unleaded at 91 octane? Could it cause any damage or warranty issues down the road?

where in Cali is this 93 Octane station? Of course....93 is better than Cali Craptane 91.....unless its E85 based or something. Could you share more info on where this station is? TIA

The station is in San Jose on Almaden Expressway. I often see M3's and Corvettes filling up with it. I was just wondering if my car is already setup for California emissions if 93 would cause any issues.

Is that the 76 on Almaden and Foxworthy ?
I get 100 from there, I'd love an option in between 91 and 100 though.
The sticker on the inside of my gas flap says "93 min" so I guess it's ok.
Mines an older 996 though.

93 is all we can get in Florida. I travel for business in 9 southern states and 93 is the only Premium gasoline. No problems with 93.
BTW, I use 89 in my BMW x5 4.4i. BMW says to use 91 or better but I can;t tell the difference. It's a lease so who cares anyway.

The bottom line here is that when using a lower octane in an engine that doesn't knock, it will produce the same power when using most expensive racing gasolines.
However, sometimes when you use another fuel, the engine suddenly seems to run better. This is for other reasons including improvement in engine breathing (volumetric efficiency) due to quicker evaporation of fuel upon entering combustion chamber.
Higher octane fuel provides a higher level of protection for the engine, especially when running in hot climates.

I understand the above statement regarding knock but most car manufacturers say you can run lower octane but you just don't get the advertised power rating - is that correct?
