W211--you must really want to get everything out your tank of gas

...on a serious note, I guess MB doesnt want to leave people stranded and are giving themselves a 15 mile cushion by stopping the per mile countdown at 15 miles (who knows how accurate they are really, we got my buddies Jeep Grand Cherokee down to 0 miles, but were still going). I for one usually try to fill up once the light comes on, if not a little bit before then. My mom always said to have at least a 1/4 tank, but I think that's a little bit too much. That being said, I have no exact information as to why they stop at the 15 miles to empty
