^^This.

I never have pushed the Miles to Empty past 0, but have gotten to 15 miles to go once.

I use Lucas every other fill up. However the problem is not necessarily fuel starvation when "running on fumes", its that you can burn out the in tank fuel pump which heats up the harder its working to suck those fumes up. If you continually run down to 0, then you may be replacing that fuel pump sooner.
