I wonder how that affects the fuel mileage in the meanwhile.  Do we
lose that much in extra gas?

30,000 miles/30 mpg = 1000 gallons of gas.
30K/26 mpg = 1150 gallons of gas.

So if that tuneup at 30K nets you 4 mpg, you save 150 gallons of gas.
Wait, the mileage degrades in some non-linear fashion from 30 to 26, 
so it's less than that.  Screw it, it's not worth it.  Too close to 5pm
on Friday for me to care, but you get the idea.  Your mileage
improvement
has to be drastic with the tuneup to make it worthwhile ... Wait, that's
just the first 30K.  What happens after 50K? How bad is it running then?

Screw it, I'm going home to clean my collection of broken 2002
distributors.
