Is there any oil that help seal oil leakage in a car machine?

I heard some of my friends said that there is a kind of oil that helps seal small oil leakage in a car machine? Is that right and how does that work? Is there anyone who can come up with an answer?Is there any oil that help seal oil leakage in a car machine?
No. Once a seal starts leaking, it only gets worse. Any sealer that would stop an oil leak could stop up an oil passage and lead to oil starvation. You are probably thinking of a mineral oil compound that expands the seals. This will lead to seal failure. Another possibility is using an oil thickener. That's not good either, especially if you run in cold weather. I've NEVER had any luck with any quick fix product to stop an oil leak, radiator leak, power steering leak, transmission leak, or urinary tract leak. Best and more permanent solution is to replace the seal.Is there any oil that help seal oil leakage in a car machine?
Okay a very simple concept us mechanics have you can never fix a mechanical problem with a chemical and yes there is but its bad on your engine can't tell you how it works in simple terms only big terms but i recommend finding the leak and getting it fixed
Clean the engine up and find the leak and put in a new gasket. That mechanic in a can stuff doesn't work.
