Hey all, I don't get my Si until the coming week (just in time for Christmas) , I don't have my owner manual yet of course. Is the minimum octane 91 on these cars ? My last 1.5 l turbo Civic ran on 87 Octane but I see premium fuel is needed for the Si. I would be happy if I could run 89, but if 91 is the required fuel then I will run it. Thanks for any replies.

Interesting that you brought up Engineering Explained. I was just thinking about his most recent video which references one of Gasoline Direct Injection's problems, which is Low Speed Pre-ignition. In the video he was pointing out how important good oil is in preventing this, but I was wondering if higher Octane gasoline might also help.
