Culio made his Mersin Idmanyurdu debut in the opening game of the season against Orduspor, where he came on as a substitute in the 60th minutes, in a 1–1 draw. In the next two follow up matches, he scored goal against Sivasspor and Eskişehirspor, adding his goal tally to two by the end of August. Since joining Mersin Idmanyurdu, Culio became a first team regular for the side. It wasn't until on 27 January 2013 when he scored twice, in a 3–0 win over Sivasspor. After scoring his sixth goal against Gençlerbirliği on 17 February 2013, Culio, however, was then sent–off for second bookable offence, in a 2–1 loss against Kayserispor on 3 March 2013.
