It isn't good to run a tank too low because the fuel keeps the internal fuel pump cool; running too low too often and for too long a duration lets that pump heat up too much and reduces its service life. The reason I ran low on a few occasions was due to driving cross country late at night and many fuel stations were closed.
a friend of mine never has more than 1/4 tank of gas in his car. He just goes and puts a few dollars in to get him to work and back (I know, it's weird
). He has gone through fuel pumps on all of his cars and I keep telling him it is because of heat but he doesn't believe me. I remember replacing a fuel pump in an old 92 taurus SHO I had but not since then, they are pretty reliable. I don't know if the heat thing is true or not but it sure seems like it would be.
