Motor oils and lubricants are formulated with many different types of additives. These additives are necessary to prolong the life of the oil, stabilize biochemical components, reduce friction and remain compatible with modern combustion engines. As vehicles age, o-rings and seals lose their elasticity, harden, and shrink, allowing engine oil to leak and allow contaminants to enter the system.
Bar’s Motor Oil Stop Leak is formulated to prevent, restore, and recondition old and worn seals, o-rings, and gaskets to stop engine oil leaks. After application, drive 320-480 km to allow Bar's Engine Oil Stop Leak to penetrate the motor seals and seal the leak.
