They are both hydrocarbons derived from petroleum, but they are quite different from each other.

Explanation:

Petroleum ether is a petroleum fraction consisting of #"C5"# and #"C6"# hydrocarbons.

It boils in the range 35 °C to 60 ℃ and is commonly used as a laboratory solvent.

The name "ether" is used only figuratively because the mixture is almost as volatile as diethyl ether.

Mineral oil is a colourless and odourless mixture of petroleum hydrocarbons with a boiling point of about 310 °C and carbon numbers ranging from #"C15"# to #"C50"# (mostly from #"C16"# to #"C18"#).

It is commonly used as a lubricant and laxative and as an ingredient in lotions, creams, ointments, and cosmetics.
