STP | Engine Stop Leak Rejuvenates Seals and Gaskets - 428ml

STP Engine Stop Leak (428ml / 14.5 Fl. Oz.) is a professional-grade, highly concentrated chemical oil treatment masterfully engineered to target, seal, and prevent fluid loss across internal combustion assemblies. The product is contained in a premium, ergonomically curved black plastic bottle designed for precision, spill-free pouring into oil filler necks, topped with a heavy-duty black screw cap. The canister features a sleek black and textured grey commercial label showcasing the iconic STP corporate stamp alongside an explicit "Rejuvenates Seals and Gaskets" trade stripe, followed by detailed technical statements validating its built-in viscosity enhancer and mechanical protection capabilities. Formulated with advanced polymeric conditioners, this premium additive directly infuses into dry, brittle, and shrinking elastomeric oil seals, swelling and restoring rubber materials back to factory parameters to secure vital engine lubrication boundaries.

Specifications:

• Brand: STP.

• Product Line: Advanced Engine Oil Conditioners & Heavy-Duty Stop Leaks.

• Product Name: Engine Stop Leak.

• Classification: Gasket Conditioners, Viscosity Enhancers & Oil System Additives.

• Net Capacity: (428 ml).

• Engine Safety: Guaranteed safe formulation; does not negatively alter or affect any internal mechanical engine component.

• Country of Origin: United States of America.

Benefits:

• Immediate Leak and Seepage Mitigation: Functions as a fast-acting corrective agent that successfully stops minor oil leaks and prevents external oil weeping from critical casing tracks instantly.

• Cylinder Head Gasket Protection: Delivers robust chemical conditioning to protect and seal essential cylinder head gaskets, valve cover gaskets, and multi-layer steel boundaries.

• Valve Stem Seal Restoration: Effectively targets and fixes hardened valve guide seals (valve stem seals), dramatically cutting down volumetric oil consumption and stopping tailpipe smoke.

• Adaptive Rubber Material Expansion: Works seamlessly by soaking into, expanding, and rejuvenating deteriorated gasket profiles that have broken down due to weathering and severe heat loads.

• Integrated Viscosity Enhancer: Features a specialized technical polymer block that fortifies existing engine oil film thickness, optimizing hydrodynamic lubrication across hot mechanical journals.

• Moving Hardware Lubrication: Actively lubricates internal moving engine parts, minimizing frictional drag and reducing systemic component wear without thinning active oil packages.

How to Use:

1. Ensure the vehicle's engine is fully warmed up to a stable operating temperature, then shut off the ignition before application.

2. Remove the engine oil filler cap and pour the entire 428ml volume of the STP Engine Stop Leak container straight into the crankcase.

3. Always monitor the oil dipstick line after addition to verify that the collective fluid level does not breach the manufacturer-mandated maximum capacity line.

4. Drive the vehicle normally; the advanced chemical agents require continuous thermal circulation and mechanical rotation over several driving intervals to allow the rubber matrices to fully absorb the conditioners and achieve a complete seal.

5. Integrate one 428ml container consistently during regular scheduled periodic oil changes as an absolute preventive shield against future gasket drying and environmental cracking.

Suitable For:

• All passenger cars, commercial utility vans, and sport utility vehicles (SUVs) utilizing gasoline or diesel configurations experiencing minor oil weeping, cylinder head boundary leaks, or main crankshaft seal seepage.

Note:

• This trade-grade chemical additive is a highly potent corrective and preventive oil system stabilizer built to rigorous American standards; to safeguard your vehicle's delicate internal components against performance-robbing dryness and catastrophic oil starvation, it is highly recommended to integrate this premium American fluid into your standard vehicle upkeep plan.
