Lucas engine oil stop leak

I have a oil leak somewhere on my 96 4.9. It's not terrible probably a litre or two between oil changes. I'm thinking about using Lucas stop leak. Wondering if others have used it and what kind of results they had. Engine has 335000km.

Not a believer in that kind of stuff. Degrease the engine, find the source of the leak then make the appropriate repair.

It works about as well as any of them. Which isn't very well. If you're losing a litre or two between oil changes, that's a heavier leak than that product will even put a dent in.
