A:AnswerNo, I don't think so. We've used extra virgin coconut oil, butter flavored popcorn oil, and canola oil. My favorite is the coconut oil and no added salt.
A:AnswerNo, it does not have an auto-shutoff. As soon as it starts to pop slowly you must turn off the heat dump popcorn into the bottom of the machine. If you leave the light on it will also stay on all night. The bottom of the machine has a heater built under the popcorn tray so it is not advised to keep the light on all night. In other words, you can not set this machine unattended.
