Ive been running 92 octane (which is the highest you can get here without a booster) on my 7 for about 2-3 months. I know its more expensive and stuff, but i have like 3 stickers on my car that say to use unleaded, then 92 octane, then 93. I dont know if somebody is just tryin to **** with me or what. Do you think its safe just to switch over tommorow to regular?

 

Depends on if your turbo or not. If not, 87 octane is just fine. If turbo, keep running high octane.

 

Why dont you just search. This has been covered a million times on this forum. Read the threads and make a decision for yourself.

We dont need another octane thread.

 

all N/A's are tuned for 87 octane from the factory.

 

Yes, for N/A, run 87 or lower if you can find it. The 787B ran 82 octane I think.

Edit: It is ok to run higher octane in NA, I did for the first month I had mine, but it will run "better" on 87.
