STP | Engine Stop Leak - 300ml

STP Engine Stop Leak (300ml) is a premium-grade, highly concentrated chemical oil treatment masterfully engineered to target, seal, and prevent oil loss from critical internal combustion assemblies. The product is housed in a distinctive, ergonomically curved black plastic bottle optimized for steady, spill-free dispensing into engine oil filler necks, topped with a heavy-duty red screw cap and highlighted by a sophisticated black and textured grey commercial label showcasing the iconic STP corporate stamp alongside an explicit application statement validating its compound compatibility across both gasoline and diesel platforms. Formulated using an improved concentrated detergent and polymer matrix, this trade-grade fluid actively penetrates dry, calcified rubber interfaces and gaskets, safely swelling elastomer fibers back to original dimensional specifications to permanently block external leakage tracks.

Specifications:

• Brand: STP.

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

• Product Name: Engine Stop Leak.

• Classification: Engine Oil Treatment & Gasket Rejuvenators.

• Net Capacity: 300 ml.

• Engine Compatibility: Universally formulated for all Gasoline and Diesel powertrains; safe for multi-grade mineral and synthetic oils.

• Country of Origin: United States of America.

Benefits:

• Comprehensive Leak Mitigation: Functions as a highly adaptive corrective agent that helps stop minor oil leaks and rejuvenates seals and gaskets throughout the engine block.

• Elastomeric Polymer Conditioning: Delivers essential plasticizers directly into shrinking or brittle crankshaft main seals, valve stem seals, and timing cover gaskets to recover elastic seating.

• Advanced Improved Formulation: Features a specialized chemical balance that blends seamlessly with existing crankcase oils, resolving leaks without thinning oil viscosity or altering crucial operating film strength.

• Oil Starvation Defense: Decreases chronic oil consumption and environmental oil weeping, successfully maintaining oil pan levels to avoid catastrophic top-end metal friction.

• Economical Labor-Free Maintenance: Offers an intelligent, fast-acting mechanical workaround that avoids expensive vehicle teardowns and machining labor for basic gasket weeping issues.

• Proactive Thermal Protection Shield: Deposits a micro-thin, heat-resistant barrier across rubber surfaces, defending them from hardening and cracking caused by localized engine bay thermal loads.

How to Use:

1. Ensure the engine has been running and is at a warm, stable operating temperature, then shut off the ignition.

2. Remove the oil filler cap and pour the entire 300ml volume of the STP Engine Stop Leak container straight into the crankcase.

3. Always monitor the active dipstick line after application to verify that the combined fluid volume does not exceed the manufacturer-mandated maximum capacity.

4. Drive the vehicle normally; the advanced chemical agents require continuous thermal circulation over several hundred kilometers of actual driving to fully cure rubber components and secure a total seal.

5. Integrate one 300ml bottle consistently during every scheduled periodic oil filter change as an absolute preventive shield against future engine gasket drying.

Suitable For:

• All passenger cars, transport vans, and sport utility vehicles (SUVs) experiencing minor oil weeping or external seepage from oil pan lines, valve cover boundaries, or main crankshaft seals.

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 compression loss, it is highly recommended to integrate this premium American fluid into your standard vehicle upkeep plan.
