Current options on multipurpose lifters?

Oil additives may work on those cars where varnish is causing the lifter to hang up. My experience has seen more issues with a weakened internal spring, only fixed by replacement. Like you though, I have never seen oil additives fix anything. Thanks for bringing it up.

I have a time or TWO but that's about it. In the case where maybe a piece of dirt or "something" is hung up in a lifter, there's a small chance some of those additives can work. Certainly worth the try, IMO. You never know.
