Femmzoil is the robot fluid found in fembots, and the opposite of testosteroil. Bender had this for a brief time when he became Coilette during the 3004 Olympics so that he could take away 5 gold medals (4ACV13).
- Femmzoil refers to the word "female" and the American oil company Pennzoil.
Farnsworth: Dear Lord! A coaster! The Femmzoil must be sachet-ing girlishly into your processor.
Since Femmzoil is a main component of fembots, it technically appears in many episodes. This list only deals with significant appearances.
