Try WD40. I'd spray it on and let it set for at least a half hour. It works at taking out sharpy marks off clothes and also tar on car surfaces without damaging the surface. Good luck.

Another old method of removing grease and paint from work clothes is to wash them separately using [electric] dishwasher detergent...it's pretty harsh on clothing, so don't wash the everyday clothing with this method...

Try rubbing lard ( shortening) into the stain and then wash as normal, it may take a few attempts, but the grease in the lard/shortening will eventually take out all the oil stains.
