Octane
 

I am only working on my third tank of gas - so I haven't had much time to experiment. Anybody notice performance/gas mileage differences between 87 - 91 octane gas?

I have the 2.0, but it would be interesting to hear about the 2.3 also.

Seems I remember reading an article, that the standard 3 is designed to operate most efficiently on regular fuel, and that any higher octane offers no benefit.

and have you seen the price of gas now??
holy crap....if gas was cheaper, like, half the price it is now, i might actually consider it....but now im paying almost abuck a litre....
it's bull....but what do i care...we use dog sleds up here in canada....lol yeah, right

I agree. A higher octane is'nt going to do anything worth the extra cash. Even every-so-often. Stick with the Reg. and feel good. When i joined the Mazdaspeed3 club, i had to start pumping Premium.

RE: Octane
 

Yep. That is one of the only drawbacks to the S3. But with the increased mileage over my Explorer, I still come out ahead.

I always ran regular when I had my 3 and she ran strong. But with the turbo I'm switiching over to a higher octane, as they say you should with the ms3's.

>.> i may be wrong but i believe you have two choices, Premy or harm the engine in the case of the MS3.
