Non-stick spray substitute
Non-stick spray is mostly canola oil plus some water and an emulsifier. So canola oil would work well as would most vegetable oils.

To get an application closer to non-stick spray you can pour some on a paper towel and rub it on your cooking surface. You can also buy misters that are made especially for this purpose.

Crisco is mostly soy bean oil and palm oil. It will technically work well, but personally I find the flavor of palm oil to be a little stronger and not as appetizing as other vegetable oils.
