WORKED FOR ME
I've been using this product ever since my rear main oil seal on my 1999 subaru forester started leaking.
The leak was bad as it would leave oil drops on the ground after sitting over night. My car doesn't do this anymore since I started using this product a few years ago in 10w/40 grade oil.Read full review...

Caused headgasket Leak
Be careful with cheap additives. If you have a simple leak somewhere else address it. Or you will regret it like me. Now my headgaskets leaks an exhaust blows thick white smoke after adding this with the right oil an %. It has clearly worn every engine seal now. Read full review...

This stuff worked for me!
Has reduced oil leaks and just about eliminated exhaust smoke in my little Vitara, worth trying in an older engine.

an expensive expense I could not afford.
Purchased 2 for my diesel van.
Used both for 7.4 Litre oil fill.
Had a small oil leak.
This did not stop the leak.

It Actually Works
After buying another Subaru WRX it became apparent there was a small oil leak coming from the valve cover spark plug gasket. After changing oil and adding the full contents of the stop leak and driving it to what the instructions said the leak sealed up and didn’t leak anymore. I definitely recommend this productRead full review...
