<human>:  Can petroleum jelly be used as fuel in a car?
<bot>: No, petroleum jelly cannot be used as fuel in a car. Petroleum jelly is a byproduct of petroleum, which is a naturally occurring hydrocarbon liquid found underground. Petroleum is a highly reactive liquid used to power cars. Petroleum jelly is a solid substance used as an ointment on cuts and scrapes to promote healing. Petroleum jelly does not oxidize on exposure to the air and is not readily.
