All PepBoys, Harbor Freights, and such offer a suction pump with about a one liter capacity. Keep your 600W in the house during the winter, suck a pint out of it with the suction pump and then pump it into the rear end to almost the bottom of the filler threads.
Maybe this link to Harbor Freight will work.
