The EZ Oil Drain Valve for passenger cars and light trucks is approximately 7/8" long. This means that the valve only extends out 1/2" more than the standard plug head outside from the oil pan. The extension on the H-Type Valve extends from the valve for another 5/8". It is not recommended using the H-Type Valve for vehicles with low clearance, as the valve may protrude out too close to the ground.
