I been filling up with top tier 87 octane since I bought it new 1 1/2 ago.

I haven't put a single tank of 91 octane ever. The manual recommends it, and it's not required. It will not void your warranty.

This fuel thing is waaaay overrated.

Yes you'll get better performance. But who races around town and worries about how the car performs. I'm not making a living racing this thing on a track.

I've never had any knocking or other issues. I have 34,000 miles.

I average 22 mpg around town. I've seen as high as 29 mpg on a long road trip at top speeds of 65 mph.
