Where's the proof? Where's the evidence that points to zinc being 100% equivocally responsible for any form of engine damage whatsoever? And I mean BEYOND A SHADOW OF A DOUBT. I want to see it.

What are you ask for proof of? I NEVER said zinc hurts parts. I said too much kills power and compromises the oil package. That’s 100% fact.

You can search the web for SAE articles and many, many industry tech papers where this is covered.

Look it up. It’s easy to find.
