The Lucas Oil 10008 Power Steering Stop Leak is a 12-fluid-ounce power steering additive designed for use in hydraulic power steering systems. Its formula is intended to restore and condition elastomeric seals while helping address minor seal leaks. The solvent-free formulation also helps clean and reduce friction within hydraulic power steering systems. Lucas Oil states that the product can help reduce squeals, whining, hard spots, and other symptoms associated with worn rack-and-pinion power steering components. The product is compatible with power steering fluids. For systems experiencing a leak, Lucas recommends adding the product until the leak stops, typically using one bottle. Always follow the vehicle manufacturer's specifications and the product directions before use.
