I'm still getting pretty much what I always did; right around 50MPG. I've always thought the trip meter avg mpg was a little high, but right now it's reading 52.6MPG after 14,000. (I don't reset it much, like I used too)

Yes, I have been very happy with the vehicle and actually since I started this post the light has stopped coming on. For now.

The weather has cooled a lot since the light first came on, so it's looking like it is heat related. I'll see.

Good luck with yours. I don't baby mine, but I don't really beat it either. Just keep your foot as light as possible and you'll be happy with the mileage.
