Do you know what it is designed to do?
It has extra rubber seal conditioner to prevent leaks and that's it. It does that well and it's not a meme, but it won't make your high mileage car run better.

It can slow down oil burn, which is a good thing. Worth trying out if you have issues with that. If not then no reason to use it.
