How Sealers Work

Engine oil leak sealers are designed to repair and prevent leaks in your vehicle’s engine. Understanding how these sealers work can help you make an informed decision when choosing the best product for your needs.

Chemical Composition

Oil leak sealers typically contain a blend of specialized chemicals and additives that are specifically formulated to interact with the hot engine oil and create a durable seal.

Sealing Process Explained

The sealing process begins when the sealer is added to the engine oil. As the engine runs, the sealer circulates throughout the system and comes into contact with the areas of the engine that are prone to leaks. The specialized chemicals in the sealer react with the heat and pressure in the engine, forming a tight seal that prevents oil from escaping.
