ABSTRACT:
Apparatus for maintaining the quality of lubricant and level of lubricant in an internal combustion engine without having to remove lubricant. The oil pan or crank case normally mounted on the underside of an internal combustion engine is modified to include a deep well in the lower wall thereof which has a breadth substantially less than the breadth of the oil pan so that a substantially reduce volume of oil is required to safely operate the engine. Apparatus is also provided for supplying make-up lubricant to the engine while the engine is operating and includes an air impervious reservoir containing make-up lubricant. A conduit is coupled to the lower end of the reservoir and is received in the deep well. The conduit includes a lower end having a discharge opening disposed at the level of lubricant in the well when the engine is operating. If lubricant is dissipated and the level of lubricant drops below the opening, make-up lubricant falls, under the force of gravity, through the conduit until the level again rises to cover the opening.
