These additives usually work on the principle of softening hardened seals and to an extent, they may work but as with all products like this, only for a limited time and under quite special circumstances. I reckon they'll only work for garter-type oil seals that have age/heat hardened but are otherwise undamged. They are very unlikely to resolve a leaking gasket.

There is no substitute for getting the the root of a leak properly and resolving it.

What was the reason for your query Nigel?

jim, there are so many more addatives on the market these days that promise so much in reconditioning seals and stopping leaks, some are quite expensive addatives,

the reason why I asked was accertain which was considered to be the best of the bunch that is if anyone has plundered 20 quid on a bottle of it.
