How do oil leak additives work?

Oil leak additives are products that are designed to stop or reduce oil leaks in engines. They work by swelling up the seals and gaskets in the engine, which helps to prevent oil from escaping through small gaps and cracks. These additives typically contain chemicals such as esters, detergents, and seal conditioners that help to soften and expand the seals, making them more pliable and less likely to crack or leak.

When the oil leak additive is added to the engine oil, it circulates through the engine and begins to work on the seals and gaskets. Over time, the seals become swollen and more flexible, which helps to prevent oil from escaping. Some oil leak additives also contain seal repair agents that can help to permanently repair damaged seals and gaskets, which can save the engine from expensive repairs.

It's important to note that oil leak additives are not a substitute for proper maintenance and repair of an engine. If an engine is leaking oil, it's important to have it inspected by a qualified mechanic and repaired as necessary.
