Alternatives to Engine Oil Stop Leak

There are several alternatives to engine oil stop leak that are less likely to cause damage to your car. These alternatives include:

• Seal conditioners: Seal conditioners are similar to engine oil stop leak, but they are less likely to damage seals. They work by softening and reconditioning seals, which can help to stop leaks.
