PURPOSE: A lubricating hose for reducing wasted oil is provided to prevent the waste of oil by controlling the length to prevent the lubricating hose from being bent. CONSTITUTION: A lubricating hose for reducing wasted oil comprises a length adjustable portion(110) and a length non-adjustable portion(120). The lubricating hose can be folded and unfolded. The length of the lubricating hose is freely adjusted. If a car is far away from a lubricating body, the length adjustable portion is unfolded to extend the length of the lubricating hose.
