Picked up my new 3is yesterday and I was wondering what the recommended fuel grade is...

I distinctly remember the dealer telling me that I could put in regular unleaded like a normal Honda, but I looked at the service manual it says to put in 91 octane...

Can anyone help clear this up for me?

Thank you! I thought as much

 

dealer told us the same when we got ours. And we had specifically asked.

Then as I started reading the manual, I saw the premium fuel part. So we switched to that.
