Dawn Soap applied to the oil stain sometimes works.
If the oil stain is fresh and not set, sometimes a soak in water and amonia will get it out.

As a mechanic and a printing press operator before that I have a lot of experience with this. GoJo or Goop hand cleaner works the best. Apply it to the stain on both sides before washing. Works every time.
I use this on work shirts that don't have much value so if the stain is on expensive clothing try it on something of little value first. Hope it helps.
