If you aren't willing to burn it your MB then don't even think about your car......
Never had a problem burning old pre-mix in my cars. Usually, the amount is less than a quart, and that is added to a nearly full tank of gas in a car. (14-22 gallons depending on which car) The old fuel can cause hard starting and rough running, but is rendered harmless when mixed with several gallons of fresh fuel. A modern car engine will burn it cleaner than burning it in a bonfire (dangerous and stupid), and letting it evaporate contributes to hydrocarbon emissions. Besides, gas doesn't evaporate completely. You'll end up with a lot of the heavier (read sludgier) components after the light aromatics evaporate away.
