Suggestion
I personally find 110 octane is perfect for when my car is loaded up with my three spare tires for a trip to the local grocery store where I make sure to jack up the car and check for any oil leaks, small mammals, and stone chips, before entering said grocery store.

Suggestion
I can't run 110 octane because I need that room for more spare tires.

Suggestion
Unless you’re running the engine very hard (extended use on the track etc) 92 is enough.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Have an 01 C4 3.4L. We can only purchase 92 octane unlead. To bring to the octane level to about 96 by mixing 1/3 100 LL avgas with 2/3's 92 octane unleaded, would this cause any harm to the motor?
Thanks
Mark the L L in this type of avgas stands for low lead. Even in a diluted form this amount of lead will kill your cats. Unless you’re running the engine very hard (extended use on the track etc) 92 is enough. The largest number of Porsches in the US reside in California, mostly surviving well into old age on only 91 Octane.
What is the temperature and altitude where you reside? The need for higher octane diminishes at lower barometric pressure.
ARE YOU SNIFFING GLUE!!!!!
NEVER PUT ANYTHING OTHER THAN UNLEADED IN
If you have put in LL already, you may have damaged your cats already and they are big $$
92 octane is more than fine and most places in the USA the highest normal gas is 91. In any case the ECU will adapt even if you put in 87.
Putting in higher than 93 is a waste of $$ as it does nothing unless the car has been tuned for it, no matter if you are on the street or even long track sessions or driving hard
Do yourself a favor and do a search here before trying such things
Also, might be nice to introduce yourself on a first post, Pics too as without pics, it ain't real
I personally find 110 octane is perfect for when my car is loaded up with my three spare tires for a trip to the local grocery store where I make sure to jack up the car and check for any oil leaks, small mammals, and stone chips, before entering said grocery store. Safety first fellas!
You are all doing it wrong. Proper way to travel is to have AAA Van follow you everywhere, with a set of wheels/tires, spare engine, spare tranny, and trained crew of expert race drivers/mechanics/engine builders manning the whole operation.

Hi everyone. My name is Mark. Purchased an 01 996 C2 the first of Oct. last year. I haven't figured out how to include the pic of my car however, I could provide the VIN if u wish to keep it real.
Never tried glue. Never have put anything other than 92 octane, ergo,the reason for this post.
Anyway good to be here and I will figure out to get my Porsche on my posts.
Welcome. After you've posted for a while, then you can add pics. It would be a good idea not to post your VIN on a public board. Pics are fine. The 91 octane is fine for your car.
