The 06+ 2.5i's run like hammered dog crap on 87. They ping and thus pull timing on loads at certain RPM's. Switching to 91 this week I noticed an instant difference. This has also been logged by several people.
Also the IAM's are higher on our newer models while running higher octane.
I'm not talking about a ferrari vs honda difference but in layman's terms the car is happier on high octane
Wow I am so happy to know that there are others out there that noticed the same thing about the 2.5i's and 87 octane.
I knew nothing was really wrong with my car as she runs fine and smooth other than the pinging, which only happens on 87 octane.
The other interesting thing which is normal I think, is that between 87 and 93, on 93 my gas mileage is def better.
So, thanks for all the comments guys on my particular posts in this thread.
