Your fuel gauge is wrong then.

Your tank is just as big as mine. 17 gallons.

all gauges are a bit different car to car. but also keep this in mind, when the low fuel light comes on, you should have 100 miles of travel left in the tank, so there's 3 or 4 gallons right there in the bottom of the tank.

ive also noticed in my regal it only takes 13 to 14 gallons to fill it up from E.

Maybe different sub models the tank size is different? Possible?

i thought i just cleared this up.

every car has a reserve of 100 miles in the tank when the light comes on, thus leaving at least 3 to 4 gallons in the tank when the light comes on. 4 + 13 = 17 last time i checked. we all have a 17 gallon tank. plus the fuel lines and filler neck.

Just to be clear not every car is that way but the grand prix's are.
