kbb is stupid and i dont know what yall are talking about, my 03 Eclipse SPYDER takes 12.4, no a ml more. and Kbb says that the tank is 16.4!!

Check your owners manual and it should say that it is 16.3 or 16.4 gallons total.

Reserve is more than 1.5 gallons, for me, its from 12.4, to 16.3, because when my light goes off and i drive it for about 10 miles, and il fill up about 12.6 gallons... and my manual says 16.3, and i have a spyder, i dont know if that matters but.... yeah all cars have reserve tanks

Dude here's the deal, let your car run til it starts to sputter and it's about to completely run out of gas, then fill up and see if it doesn't take nearly 16.3-16.4 gallons.
