I didn't think about that. She doesn't see anything but 93 octane, which she'll be get some fresh later today. I'll be sure to NOT get crazy with her. I'm extra cautious usually through this break-in process.careful, if you had the battery disconnected, the TCCS has had its knock values wiped so you are starting at the most aggressive timing that is programmed into the TCCS until it relearns knock value. You should be using the highest octane available in you area.
