MOTUL Engine Oil Stop Leak

Advanced engine oil stop-leak formula engineered for gasoline and diesel 4-stroke engines, including turbocharged, naturally aspirated, and EGR-equipped units. Features smart polymers that expand upon heat exposure to seal micro-cracks in valve cover gaskets, oil pan seals, and crankshaft front/rear main seals. Non-clogging—safe for oil filters and viscosity integrity. Restores normal oil pressure and significantly reduces oil consumption after first application. Compatible with all conventional, synthetic, and high-mileage engine oils.
