An oil gel compositions comprising (i) between 10 to 20 wt. % of a selectively hydrogenated styrenic block copolymer, (ii) an oil, and (iii) optional additives is described herein. In embodiments, the oil gel composition is characterized as having, a viscosity at 25° C. and 10/s between 100 (See claims 2) and 200 Pa·s, a cone penetration at 25° C. from 200 dmm to 600 dmm, a drop point from 100 to 250° C., and oil separation at 100° C. from 0% to 2%. In embodiments, the oil gel composition has a viscosity ratio of 25° C./100° C. from 4 to 20 at 10/s shear rate. The oil gel composition can be used in cables for post tensioning applications.
