ABSTRACT:
Methods and apparatus to flush residual used oil from the lubrication system of an engine during an oil change. The method includes draining used oil from a tank of the lubrication system and then adding fresh oil to the tank. An adaptor or fitting is used to provide an outlet in the lubrication system to flush any residual used oil that may not have been drained along with used oil in the oil tank. The engine may be started such that a scavenging pump of a lubrication system pumps residual used oil out of the system through the outlet. Once a user observes that residual used oil has been substantially flushed from the system, the engine is stopped to terminate the flushing process.
