The invention is designed for use with diesel engine over-the-road trucks and periodically extracts a given quantity of oil from the oil pan of the engine and ejects that quantity into the fuel tank for burning along with the regular fuel. In turn, an automatic oil level sensing device continually senses the level of oil in the engine while the engine is running thus insuring a constant infusion of fresh oil into the engine oil supply thereby effectively changing the oil as the vehicle is operated and removing the need for the discrete oil change operation.
