I have a '93 sc4 and gas mileage is one thing that i always pay attention to. I think my driving conditions are pretty standard. When i'm on the highway i'm usually pushing around 70-90 mph (depends if i'm in a rush). There's something very funny w/ the ect. I normally drive w/ it off but one time i tested it and left it on after a fill up jus to see if it made any difference and i actually got better gas mileage!!! I believe that tank i got b/w 20-21 miles per gallon. but i only did it once and cant say it'll happen everytime. Normally i'll get anywhere b/w 19-20 miles per gallon so i'll drive 360 miles on one tank before I fill it. If you get the mileage you say ur getting on your SC3 then that's terrible. You should be gettin way more than me or at least better than your getting now. You're probably pushing your car too hard. Most gas consumption is in acceleration so when you in the city, take it EZ. One thing that helped me w/ my gas mileage is cleaning my fuel injection. I noticed that it gave me 1 more mile to the gallon on a full every tank so that's like 20 more miles i could have went. Jus go to your local autozone or where ever and pick up a bottle. the best advice i could give you is dont buy into the name brand. It's 20 more and doesn't do any better than the name generic stuff.

I always wait until my light lights up to fill up. I'm always too busy (or lazy) to fill up my tank right when it comes on. I usually drive with it on for about a day and a half. When i fill it up it ALWAYS says about 16 gallons. So I'm guessing that it comes on at about 4 gallons left.
