[Aesthetix]

whats your opinion on 91 fuel grade on the 2.7

I have run 87 in all of my last 3 new trucks and never had a problem fuel related in any of em......all went well over 200k miles so I just run 87 in them, heard or read long time ago most vehicles were designed to run on regular gas ( aside from high perf motors obviously)

I ran 87 in the first 1200 miles and was curious what behavior 91 would do. I'm currently on my first 91 fill up. May be too early to tell or may need another 91 octane fill up in order for the computer to fully comprehend the higher octane. What I did notice though is that it does respond better when u want it to go.
