They say the 00 Alero has a 14 Gallon tank.
Ive had my car a bit over a year now, no issues.
I religiously get 300 miles froma toped off tank to the light comes on, at which point I add 11.4 gallons or so in gas.
So Im getting 25 MPG.
I drive about 90 miles Highway and 10 city per day. I fill up twice during the week... lol
I consider myself satisifed with 25 MPG.
Anyone who is getting below 20 has OBVIOUS issues and should seriously have their car checked by a professional, not just crap shooting in the wind...
10-15 miles per gallon? Thats about what my dads 69 Z28 gets with a 327 and 410 gearing...
