On 19 January 1945, following a refit, and once again under the command of Elmer O. Wolfe, "Four Lakes" sailed independently from New York to Madras, India, via the Suez Canal, with a cargo of 100-octane fuel and 12 military aircraft on deck. She arrived at Madras on 20 February, unloaded and then sailed via Calcutta for Abadan, Iran, at the northern end of the Persian Gulf, to take on a cargo of 80-octane gasoline. She transited the Suez Canal, and arrived at Naples on 7 April to unload. She then sailed for New York, arriving on 23 April. The next day she joined another convoy, which arrived in the Thames Estuary on 5 May, two days before the German surrender. "Four Lakes" sailed from Southend, Essex, on 8 May, and although the war in Europe was officially over, the normal wartime routine was maintained, with the ship sailing in convoy with a naval escort, and arriving at New York on 19 May. On 4 June, following a refit, and under the command of James R. McWilliams, with a cargo of 100-octane gasoline and P-51 Mustang fighters as deck cargo, she sailed for Madras, India, arriving there on 4 July. She then sailed to Abadan to take on a load of diesel oil, before proceeding independently to Darwin, Australia. From Darwin she sailed with two other merchant vessels, escorted by three warships, to the Philippines, arriving at Manila on 22 August. Following the surrender of Japan on 2 September, "Four Lakes" sailed across the Pacific, and in late October, carried diesel fuel from the Panama Canal Zone to San Pedro, California. She then sailed through the Panama Canal, and arrived at Houston, Texas, on 19 November. In December, she sailed to Hamburg, Germany.
