## Summary description

Wynn's Engine Oil Stop Leak is a specialized chemical additive designed to stop and prevent oil leaks in internal combustion engines. It effectively rejuvenates rubber and neoprene seals, restoring their elasticity to prevent oil loss. Compatible with all mineral, synthetic, and semi-synthetic engine oils, this treatment helps maintain proper oil levels and reduces engine oil consumption without affecting oil quality.

## Long description

Wynn's Engine Oil Stop Leak is a high-performance chemical treatment formulated to address and prevent oil leaks in internal combustion engines. By targeting the root cause of leaks, this additive works to rejuvenate hardened or shrunken rubber and neoprene seals, restoring their original elasticity and sealing capability. It is designed to be fully compatible with all types of engine oils, including mineral, synthetic, and semi-synthetic varieties, ensuring that it can be used across a wide range of vehicle makes and models without compromising the lubricating properties of the oil.
Advantages
The primary benefit of using this additive is its ability to effectively stop minor oil leaks and prevent future seepage by revitalizing the engine's internal seals. By maintaining the integrity of these seals, the product helps to prevent oil loss, which in turn supports consistent oil levels and reduces the frequency of top-ups. Furthermore, the formula is engineered to be safe for the engine, as it does not alter the viscosity or the chemical quality of the oil, ensuring that the engine continues to operate under optimal lubrication conditions while minimizing the risk of environmental contamination from drips.
Suitable for
Engines experiencing minor oil leaks from seals
Preventative maintenance for older vehicles with aging rubber seals
Compatible with petrol, diesel, and LPG engines
Use with mineral, synthetic, and semi-synthetic engine oils
When it may not be suitable
This product is not intended to repair mechanical damage, such as cracked engine blocks, blown head gaskets, or deep gouges in metal surfaces. If the oil leak is caused by a significant physical tear in a seal or a structural failure of a component, this additive will not provide a permanent solution and professional mechanical repair is required.
Key specifications
Volume: 325 ml
Compatibility: All mineral, synthetic, and semi-synthetic oils
Function: Rejuvenates rubber and neoprene seals
Application: Internal combustion engines
How to use
To use Wynn's Engine Oil Stop Leak, ensure the engine is warm and turned off. Pour the entire contents of the 325 ml bottle into the engine oil filler neck. It is recommended to add the product during an oil change or between intervals if the oil level is sufficient. After adding the treatment, allow the engine to run or drive the vehicle for approximately 10 to 15 minutes to ensure the additive is thoroughly circulated and mixed with the oil. The sealing process occurs gradually as the engine operates.
What to consider before purchase
Check the oil level before application to avoid overfilling the crankcase
Verify that the leak is originating from a seal and not a mechanical crack
Ensure the product is compatible with your specific engine type
Usage recommendations: For optimal results, use the additive as a preventative measure in older engines or at the first sign of minor oil seepage. If the leak persists after a reasonable period of driving, consult a professional mechanic to inspect for severe seal damage or other mechanical issues.
