well, let me put it this way.

There's one Marathon gas station 15 miles away from my place that sells 93 octane for 10+ cents more than 87 octane (comparing to the usual 10c increase from 87-89 and another 10 cents increase from 89-93). Which one do I use? 93 octane. Gas in Martinsville is 10 cents cheaper than Bloomington, IN anyway.

It doesn't harm the car nor my pocket as long as I drive my car like a grandma during the day. BTW, I advanced my timing, too... so 89 at least.
