I think the computer is using the MPG average to calculate how many miles are left, so if you were driving "spirited" the MPG were low, as would the remaining miles on the tank at that time.

Try resetting your MPG and then see if the Miles remaining look much better after some gentler driving.

Also parking on level ground may get you a better estimate.

What yr/model do you have? I've never had that issue with my '01 S'
