Finally found a way to lift stubborn oil stains out of clothes without even having to wash them! Picked up some K2R Spot Lifter from Amazon and it works great for pulling stains out of clothes, no water needed. Just spray, leave the room (this stuff is POTENT smell-wise), let dry, and brush the powder off. Boom, no more stain. Leaves a starchy feeling afterward that is easily removed in a normal wash. Saw this on Instagram a while ago and have loved using it ever since.  See the results on this McDonald's shirt:
