Oil can refers to a metal container used for storing and dispensing oil. This term is often used interchangeably with other synonyms such as oiler, oilcanister, oil dispenser, and oiljug. Oiler refers to a tool that drips or sprays oil when pressed against a machine part to lubricate it. Oil canister is a sturdy container that has a lid and a handle that can withstand rough handling. An oil dispenser is a container equipped with a spout for easier dispensing of oil. The oiljug, on the other hand, is a container with a narrow neck used for pouring oil without spillage. Regardless of the word used, it's all about proper storage and dispensing of oil to maintain its quality and prevent spillage.
