Either way, I just put that in there as a maximum....to show that even THEN does it still make sense to pay for 91+.

One more time for all the newbies and people that don't know how to read up on something before they open their mouth. Octane boosters in the store DO NOT ADD 2-3 points! Only 0.2-0.3! Toluene and xylene are two of the top chemicals for octane boosting and can still cause damage if not mixed right. GO BUY A HYBRID if your worried about gas prices not a Z!
Time to kill this thread......

here is an article about detonation, pre-ignition and what might happen to your engine if you mis-fuel it...
kind of a long read but good

I cant even believe you are even trying to argue to point. It is not good for the engine no matter what way you try to spin it.

The ECU will retard timing well before that, as soon as it hears some pre-ignition and/or partial knock.

My comment was addressed to those who say they've never heard their engine knock on regular fuel so they imagine they're ok. In most cases, they'll never get to hear it.
