Abstract: A method for using a saturated paraffinic process oil may include: curing an ethylene-propylene-diene-monomer (EPDM) composition to form an EPDM article, wherein the EPDM composition comprises EPDM rubber and a saturated paraffinic process oil, wherein the saturated paraffinic process oil comprises: a kinematic viscosity at 100° C. in a range of 14 cSt to 45 cSt; a sulfur content of less than 0.03 wt. %; a saturates content of at least 90 wt. %; a T5 distillation point of at least 480° C.; an aniline point in a range of about 130° C. to about 150° C.; a refractive index at 20° C. in a range of 1.460-1.490; and a sum of terminal/pendant propyl groups and terminal/pendant ethyl groups of at least 1.7 per 100 carbon atoms of the composition
