I use 91, I wont go back to 87...there are noticeable differences, also, thanks to a site someone posted on here, go with no ethanol gas if you can, regardless of which octane you choose. with 91 over 87 I have seen a little better gas mileage, the raspiness has gone away, and the car feels more responsive in the lower rpms
