I just filled up a couple of days ago, so I'm going to see if it holds through this week. I usually avoid the A/C when I'm going back and forth to work, but this weeks weather may make me give in to it.
We're back to the 10% ethanol in the gas, so that will have an impact on it. I always try to stick to Shell gas; it's octane is one notch above the Phillips 66 station by us.
