On my C280, I have noticed that the first 1/2 of the gas tank reading (from 1/1 - 1/2) is only 7 gallons, while the 2nd 1/2 of the gas tank (from 1/2 - 0) is 9 gallons. Does anyone else's read like this? I know that my car is prone to a faulty fuel level sender... but maybe it's supposed to be like this!?

Thanks.
