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.

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

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.
