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

#### Explanation:

Petroleum ether is a petroleum fraction consisting of $\text{C5}$ and $\text{C6}$ 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.

(From www.sciencecompany.com)

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

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