87 octane i get like 200 miles to the tank, with 89 I get about 200 also, with 91 I get about 220-230, city driving, if its highway, I get 300 with 91, never used the others because I love my car, and she only drinks expensive stuff

these threads are always a hit. http://en.wikipedia.org/wiki/Octane_rating . if you want to believe otherwise, do so. arguing about octane rating on this site is like arguing about which came first, the chicken or the...
im still right by the way.

Nah. But you are good at badly paraphrasing other people's work.
The Wiki entry you cite is missing most of the details involved (they don't even mention sensitivity), but it is probably adequate for "arguing" about it from your perspective.
You would be better served reading Bruce Hamilton's tome on the subject.

because some cars need the higher octane.
my car has a turbo. it compresses air in the engine to generate more power. The higher compression requires a higher octane level. If I used 87, the fuel can spontaneously ignite before it's supposed to, causing severe engine damage.
This is an extreme example. For most cars, they're programmed to expect a specific fuel grade, and the car's computer has been setup to be optimized for it. Using too high of an octane is a waste of your money. Using too low, and your car might experience pinging.
Due to elevation differences, climate, fuel grades, etc. You will not know what works best for you until you try it. This is also why Mazda recommends premium fuel - because it will work for everyone, regardless of their location. That doesn't mean it's the best fuel for you to use though.
If your car is NA, it would be difficult to cause real damage by trying a lower octane level.

Any harm?
