if you dont, you might get a pinging sound from the engine, which i think is rod knock? a gearhead will chime in. It isnt great to run them on mid or low grade, cuz it will kill engine i think.

This has been discussed before......what it boils down to is that knock is bad. BAD. Especially over time.
91 octane MINIMUM. Some of us have had to boost that up as we mod.
Opinions may vary, but it specifically says to run premium fuel only. And knock can destroy and engine.

When I get my heads decked [10:1 Compression Ratio], I think I may just run 89 octane and let the ECU curve the timing. That'* what will most likely happen, right guys? The ECU will compensate for the knock.. right?

On newer models they will compensate, but that doesn't guarantee that you'll be knock free under all conditions.
But you will get more power and better milage from that power, if you run premium, so i wouldn't worry about the cost of gas.

i got my 94 ssei about 2 months ago, and have been running regular ever since. i think it'* like 87 octane maybe. i haven't noticed any problems or pinging/knocking. i should be using higher octane? like the manual or whatever says to use high octane?
