Power Steering Stop Leak Case 12x1 Qt

Power Steering Stop Leak Case 12x1 Qt by Lucas Oil is a professional-grade hydraulic fluid treatment designed to seal micro-leaks in power steering systems across domestic and import vehicles. From daily drivers to modified platforms pushing higher pressures, this formula addresses one of the most common maintenance issues mechanics encounter: gradual fluid loss that compromises steering responsiveness and creates hazardous shop floors. Available as a bulk case of twelve quart bottles, this product is essential for fleet operations, service shops, and serious enthusiasts who demand reliable steering performance without system overhaul.

The proprietary formula in Lucas Oil's Power Steering Stop Leak works by conditioning and rejuvenating aged seals and gaskets within the steering pump, rack, and hose connections. Over time, exposure to heat cycles and pressure fluctuations causes elastomer seals to shrink and harden, creating pathways for fluid escape. This treatment restores seal pliability without altering the fluid's viscosity or hydraulic properties, maintaining OEM system specifications while eliminating weeping and dripping. The 1-quart bottle size allows for precise dosing—typically one bottle per system—making integration into existing fluid straightforward and controllable. Installation requires no mechanical disassembly; simply add directly to the power steering reservoir with the engine running to ensure complete circulation.

This twelve-pack case serves professional mechanics, transmission shops, quick-lube operations, and dedicated enthusiasts maintaining multiple vehicles or managing fleet uptime. It is compatible with all standard power steering systems using mineral-based or synthetic hydraulic fluids—both domestic Fords, Chevrolets, Dodges and foreign nameplates benefit equally from the treatment. For those experiencing minor steering stiffness, fluid discoloration, or visible seepage around steering components, a single quart typically resolves the issue within 50–100 miles of normal driving. Storage at room temperature ensures long shelf stability, and bulk purchase reduces per-unit cost for high-volume users while maintaining factory-engineered performance standards.
