Following the conclusion of the ceremonies, "Ohio" proceeded to New York, where she was based for the following four years. This time was spent conducting normal peacetime training with the fleet and assisting in the training of the New York Naval Militia. By 1914, the worsening conditions during the Mexican Civil War prompted the United States to begin intervening in the conflict. "Ohio" was sent to Mexican waters early that year to protect American interests in the country. In mid-1914, she returned to the east coast of the United States to conduct a training cruise for midshipmen from the US Naval Academy. After completing the cruise, "Ohio" was transferred to the Reserve Fleet based at Philadelphia. She returned to service only to conduct additional midshipmen cruises in the summers of 1915 and 1916.
