## Overview

Wynn'sPro Engine Oil Stop Leak is a 325ml additive designed to restore flexibility to engine seals, preventing oil leaks without dismantling.

## Description

Wynn's Pro Engine Oil Stop Leak - Restores Seal Flexibility & Prevents Oil Leaks Without Dismantling - Safe for Catalytic Converters - Compatible with All Oils & Engine Types - 325ml

## Features

- ✅ EFFECTIVE SEAL REVITALISATION: Formulated to target and restore the integrity of worn-out rubber and neoprene seals, this oil additive is designed to combat oil leaks by reconditioning seals within the engine system. It penetrates the seals of the crankshaft, camshaft, and valve stems, bringing back their elasticity and flexibility, which are often lost due to prolonged exposure to heat and pressure. This revitalising action helps prevent future leaks by creating a tighter and more reliable seal, effectively reducing oil loss and minimising contamination of surrounding engine parts.
- ✅ NO DISMANTLING REQUIRED: This engine oil stop leak solution offers a non-invasive approach to resolving oil leak issues. By simply adding it to the engine oil, the product works while the engine runs, eliminating the need for expensive and time-consuming dismantling of engine parts. It addresses leaks from within, flowing seamlessly through the oil system and targeting compromised areas without the need for mechanical intervention. It is especially useful in older vehicles or stationary engines where wear and tear is common, and it serves as a reliable preventive measure to avoid future complications.
- ✅ COMPATIBLE WITH ALL OIL TYPES: This supplement blends effortlessly with all mineral, synthetic, single-grade, and multigrade oils, making it suitable for a wide range of vehicles and equipment. It is also compatible with both regular and low SAPS (sulphated ash, phosphorus, and sulphur) formulations, ensuring versatility across different engine types and compliance with various emission standards. Whether used in petrol or diesel engines, with or without turbochargers, or even in stationary equipment, this product integrates smoothly without requiring changes to the oil in use.
- ✅ SAFE FOR CATALYTIC CONVERTERS AND ENGINE COMPONENTS: Specially engineered to deliver leak-stopping performance without compromising the health of the engine or exhaust system, this oil additive does not affect catalytic converters. Free from harmful substances, it maintains the original characteristics of the engine oil and does not alter its viscosity. It supports cleaner engine operation and contributes to a reduction in oil consumption and emissions by sealing leaks efficiently. The formulation is non-corrosive and gentle on engine internals, ensuring long-term reliability and safety across multiple applications, including high-performance and older engines.
- ✅ RECOMMENDED FOR A WIDE RANGE OF APPLICATIONS: Developed for universal use, this engine oil stop leak is ideal for both petrol and diesel engines, including those equipped with turbochargers. It is suitable for cars, trucks, agricultural machinery, and stationary equipment experiencing oil loss or seal degradation. Whether for regular maintenance or as a corrective measure, it addresses oil leak concerns without altering the oil system’s functionality. This makes it a valuable solution for fleet operators, mechanics, and those managing industrial engines, as it ensures operational reliability, reduces oil consumption, and prevents premature wear caused by leaking oil.

## Questions & Answers

**Q: Will this help with oil pressure low warning on a vauxhall insignia**
A: Possibly! Vauxhall oil pressure switches were always a common failure.  If the switch is faulty, nothing in a tin will fix it...  If the pressure is low due to engine wear, this is worth a try!

**Q: Can use with standard stop leak ???**
A: Hi, no, I wouldn't advise mixing additives, especially stop leak ones. They work by thickening the oil, so two lots of additive might make the oil way too thick to protect the engine.

**Q: have an oil leak coming from timing cover , on v w lt 35 diesal 2.5 , is this suitable to stop leak**
A: Not stopped mine

**Q: Hi.. is this an actual Wynns Professional product as shown in the listing?**
A: Hi
Yes the product shown on the website is the product that you will receive.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 100% works
*by B***R on 24 July 2024*

I had a small leak upon using this stuff after 200 miles plus my leak has vanished and I feel I have more engine pressure when accelerating ,Nothing more to say, I'm impressed.A* ~}

### ⭐⭐⭐⭐⭐ Less leaks than a government department
*by B***I on 10 August 2024*

I was not overly hopefully when purchasing that this would do the job. Having tried Wynns standard version a while ago for a small leak I was left disappointed. However I thought the professional version might do better as a temporary fix until I isolated the source. Well it worked far better than expected and in line with other online reviews. So my faith was restored in Wynns. I'm sure there are better products on the market but at this price point you have a good solution for your car and pocket. (Though I doubt any additive will stem a huge leak, so be reasonable in your expectations).

### ⭐⭐⭐⭐ It works
*by M***E on 27 March 2022*

Iv used this before it keeps the seals soft and slows leaks down to a acceptable level
