An "oil feeder" is a device or mechanism designed to supply oil in a controlled manner. It can be used in various contexts, such as industrial machinery, automotive engines, or even kitchen appliances. The 🛢️🍽️ symbolizes the combination of an oil container (represented by the oil drum emoji 🛢️) and its connection to a feeding mechanism (represented by the plate emoji 🍽️).
