I put some wynnes oil seal rejuvenator in mine as it was recommended to help with the leaking stem seal. I may as well have popped a fiver in the drain

As above, Iv had some success with Wynn's stop leak. But only on small leaks or weeping gaskets. It wont fix a broken gasket.

As for fuel system cleaners... I use them every now and again, I think if used regularly they maintain the system so there will be a less noticeable difference.
