You may run the engine forever using the additives and never have a problem. If so, that's great! But it's not really fixing the root issue of failing seals. Only replacing the seals fixes the issue.

BTW, here's a good discussion of the Lucas Oil Stabilizer. Basically, quality oils have additives in them to reduce wear on your engine. Lucas Oil Stabilizer doesn't have any additives so you're basically diluting your quality oil with that product.

Not a great anology but this sounds to me like patching up a leaking bicycle tube rather than replacing the tube with a more sturdy one. Given the quotes I'm getting for a proper fix are nearly 50% the value of the car, it seems a patch makes more sense at this time for me, albeit I have to make sure to refresh the patch at every oil change.
