You guys scare me with the stats, but I'll be drawn into that shortly. heh
I usually get a receipt (always debit card it) and record mileage but I dont log it... I log a lot and will incorporate it as soon as I get my lap top, since my PC is pretty toasted at the moment.
I think I'm averaging ~13, running 93Octane due to the Apten burn in. I do leadfoot it, and hate to burn time on the road, so I'm not real concerned with mileage until my financial status changes, which hopefully isnt any time soon. I'm not a gas hog, but not a conservative either and am even contemplating a car to drive and save the 4x4 for trails, kayak trips and winters. We'll see if that plan goes into effect though.
