Mustang:

Thanks for all the info you've given me. I took my car to the dealer when the tank went under 3/4 gas full but more than 1/2. His words were "to be honest if the check engine light is not on - don't worry about it." He said that they tightened up something there and he wouldn't worry about it unless the light came back on.
So, I said thanks and went on to work.
What do you think?
