Federal Mogul's LKZ Low Friction Oil Ring is designed for high power density diesel and direct injection gasoline engines. Its two-piece design employs an asymmetrical land with sharp lower edge and a radius on the upper, for optimal downward scraping. It enables reduced pressure on the cylinder wall. The result is a 50 percent reduction in oil consumption, and friction loss reduction by up to 15 percent, with excellent durability. These attributes have driven rapid market acceptance.
