The LKZ oil-control ring is a two-piece oil ring design for high demanding applications of direct-injection gasoline and diesel engines.  The ring provides enhanced engine performance, helps to improve fuel economy, CO₂ reduction and contribute to longer oil life. 

Features and benefits include:

• Patented ring reduces oil consumption by up to 50 percent and friction by up to 15 percent, compared to conventional two-piece rings
• LKZ ring provides consistent low oil consumption over the life of engine by reducing carbon build-up on critical parts of the piston
• Unique LKZ land profile for best scraping behavior with reduced contact force, applied on very conformable 2-piece Oil Ring with reduced height up to 1.5mm (25% reduction vs. standard)
• Land coatings to ensure low wear on smoothest cylinders and additional friction advantages:Cr., GDC, PVD and DLC CarboGlide^®
• LKZ  oil rings achieve proven, industry best, oil consumption with reduced tension and stable performance over the life of the engine
• Reduction of the friction losses from the complete power cylinder unit (piston + rings) higher than 15% achievable
