Octane boosting products

Vehicle Information: Year: 2002; Body Type: Coupe; Total Mileage: 6,200;

With the anemic 91 octane rating we have available [in California] it causes me to wonder what performance improvements, if any, could be derived from using an octane boost product. Is there one on the market that Porsche endorses? Is there one you know of that PCA members have used that works and DOESN't cause damage to the fuel system components?

1996 993 engine light

I'm responding to the final answer to my previous question. I took car to s car go. They knew right away what it was. They put in a fuel regulater and increased the pressure to 4 pounds. After 75 miles I think that's what it was.

2002 996 Sunoco GT100 100 Octane Fuel

Vehicle Information: Year: 2002; Body Type: Coupe; Total Mileage: 3017;

I regularly tank up my '02 996 with Sunoco's 94 octane, the highest I've found in my central New Jersey area. There are two Sunoco stations in New Jersey that sell their GT100 100 octane racing fuel. What are the potential benefits / detriments of occasionally (say one full tank every other month) "treating" my car to this highly-caffeinated snack? Thanks much in advance.

996 Fuel Filter Location

I was considering changing the fuel filter on my 2000 911 but cannot find where the filter is located. Any help would be appreciated.

Gasoline Octane

Vehicle Information: Year: 1996; Body Type: Coupe; Total Mileage: 18800;

Here in the Albuquerque area, the highest octane gas found is 91 at the pump. I have been told by apparently knowledgeable people that, due to our elevation (5600 ft above sea level), this is a more than adequate number. To me, this means that the knock sensor would NOT be activated. Do you agree, and what would be the corresponding octane number for this gas at sea level? Thank you.
