15.9. the dummy light comes on around 13-14 gal. empty. i usually fill up around 1/4, which is about 10 gal. which makes mpg calculations nice and easy

that's strange. usually the fuel light is designed to come on with a couple of gallons of "reserve" gas left, just so that exactly what you described doesn't happen. oh well, that's what warrenties are for!

I heard that it was bad to let the gas tank fall below 1/4 full
because junk that collects on the bottom of the gas tank gets picked up into the engine. any truth to that?

that is exactly right. and god help you if you get so low that air gets in the fuel lines. knock, knock. who's there? lean. lean who? lean misfire just ate your piston rings.
