I test drove a 2008 Sentra with 99 miles. During the drive I glanced at the mpg readout and it had 13.2 mpg. Later in went to 13.3.

The sales manager said because it was new and not yet through its first tank of gas, it would adjust properly after 2 or 3 fill-ups. That doesn't sound right! Can anyone help shed some light on this for me?

Thanks.
