and you can kind of tell winter(cold weather) vs warmer weather. Overall I'm averaging over 18 mpg with the 2000SS and it's an automatic so I can't complain. Some of my highway trips had local driving mixed in so what should have been an average of 24 mpg dropped into the 22 range. You can also see where some of the trips to the beach were. I also know when I changed stuff like plugs/wires, did the headers, got the tune, etc. And yes, I've put a whopping 12,715 miles on it since I got it in Dec 2006!
