The DIY porosity tests are junk science, go by how hair behaves. Two hours drying time sounds pretty fast, would have thought medium to high porosity. Even with porous hair, if its also fine it can easily get weighed down - remember most ingredients in conditioners do not penetrate.

A lot of people struggle distributing straight up oils or use way too much, they are 100% active whereas conditioner is 90%+ water. Virgin hair close to the roots often needs little to no oil, its better for ends and possibly lengths. Try using oils only as a minor ingredient in your leave in conditioner or styler, or as a pre-wash o older or damaged hair.
