87, 89, 91, what's the best fuel?

All I run in 87 in mine as well, for the following reasons.
1. It starts quicker, doesn't take as long to ignite the 87 octane as it does 93.
2. Throttle response feels to be much better on 87, anything higher seems to have some lag.
3. Less soot in the tailpipes when running 87, tells me I am getting a more complete burn.
4. No pinging or strange noises from the engine.
5. Seems to just run better all around, much smoother.
For these reasons I use 87, and from what I have read on the board posted by Rotarygod and the Mazsport threads, just because Mazda "recommends" doesn't mean you have to use it. I feel they are just following the trend of "all performance cars have to have 91 or better now, it just makes more power", kinda logic. Basically just a marketing gimmick.

I guess whatever you feel comfortable with. Hell, put glow plug fuel in the car if that is your preference. People are going to use whatever fuel they want. Then they try to justify it in their own mind using all sorts of evidence, alot of it unreliable. Then when something happens to their motors as a result of their decision to use gas that is < that recommended by Mazda (I guess they put that sticker inside the gas cap lid cuz they had extras to use up) they will bitch and moan about how unreliable the Renesis is.
So here are MY justifications for using Premium ONLY (and only mine).
1) Mazda engineers recommend it.
2) My own experiment (one time test) had the motor pinging using 89 Exxon.
Prolonged pinging can and will damage the rotor face cuz its THINNER than the old 13b rotors used in the RX-7.
3) Same 89 Exxon experiment decreased performance.
4) When it comes to my 8, I don't skimp.
Your results may vary and I dont care that they do.

Valpac, you are right, it all depends on your car and how it acts. Some do not like the cheaper gas, some cars love it. You just have to try the stuff you want, and see if it can handle it.

I know for resetting the ECM I can just disconnect the battery and reset the ECM that way, but is there a way to do it without loosing my radio stations and such, maybe some crazy pushing the gas and brake pedal while holding the car in 6th and pushing the tripometer or something?
