After reading this string of posts, I decided to run some regular (87 octane) through Vera. First two tanks I actually got 12 & 15 miles more out of each fillup, compared to mid grade fuel. Now, into my third tank, I am noticing that parallel twin "ping" that is as distinctive as an AK47 in comparison (if you heard it, you won't forget). Don't want to disagree with anyone, but I am going back to 89+ octane.
