Re: Do you use 87 or 89 octane?
Jim, you're completely correct about that if I wanted to track any long-term changes in mileage. Since I'm so new to this car and I'm going to immediately make the switch, I'll probably never know. But we'll see what the mileage looks like from here on out.
So far, it looks like I'm getting 18 pure city (tons of stops, going less than 20 mph it seems) and 24 mixed. Not bad.
One of my other concerns is avoiding potential damage by supplying the engine with the the optimal octane, as well as letting the engine perform to the fullest of it's potential.
Good news is, I found a top-tier gas station (Shell) that costs exactly the same as the cheap stuff I've been using. Never had a problem with the cheap stuff in the past, but I feel like my Bu deserves the best...
