I agree 100%, It probably wasn't the first the the car has had 89 or worse in it believe it or not.

I think the ECU should automatically retard timing when knock is present. You should just have a loss in power. Keep feeding in 93/91 as you can (don't wait till the tank is empty) so you can increase the octane in your tank.

You'll be fine, the ecu will sense a little detonation and will pull a little timing.

Well if it's perfectly fine to drive on 89 octane, then how come the gas tank lid has a warning label that says "PREMIUM ONLY"

A LOT of cars have that. My car says REGULAR ONLY but I put in premium all the time and it seems to LOVE that stuff. It's like cat-nip lol.
