[s-cars] Fuel mileage questions

[Jason Butler]

I have owned my 93 S4 for 3 months now and am wondering what kind of fuel 
mileage is normal.  I have been getting around 18 mpg which includes quite 
a bit of city driving and about 40 miles a day of highway driving.  With 
gas prices going up so much here in Denver I would like to maximize my 
mileage.  the S4 is completely stock with 180K miles on it.  Any thoughts 
on what will maximize mileage?  I don't drive it too hard because I know 
when you get into high boost it sucks gas.

Thanks
Jason
