How often (mileage) should you change the AF? I usually always figured 15,000 miles (valve adjust intervals) but the local AutoZone has 6,000 printed on their shopping bags..

Mine has a good 13,000 on it now (put it on in June when the car was bought...)

I routinely only get about 21.5-23.5 MPG per tank, mixed driving, though I took it on a 1 hour trip doing between 72-80 and then intown only to go back home at the same hi speeds. That fillup got me 25.4 mpg. Doing 60 on the two lanes for 100 miles to my grandparents will net me about 28.

Do these numbers sound about right?

In case you're wondering, yes, I do drive slightly hard, but not really hard. (I.E. I go easy enough that I have a good "smoke reserve" for when I need it!)
