Obviously i only go with supreme, just because i couldnt imagine driving with anything less. What about you guys? I know gas is becoming pricey... what do you drive around on?

You are doing more harm then good to your car. Do a search on the internet or in this forum and you will know why.
how is that? I also own a BMW M3 and it only accepts supreme. How can this be bad for a car?? :?:

Isnt the M3 a 12:1 compression engine? Thats why it needs supreme...higher octane just mean it is more resistant to burning, putting supreme in a low compression engine like the Mazda 3 is suicide!
very well said. I never thought about it like that... and i will definitely then go with the midrange gas rather than supreme. I cant complain... if its better on my engine and better on my wallet... i should just shut up and smile. :)
