    5.0 out of 5 stars It’s a GM requirement for Crate Motor installs.

    (function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } It’s probably snake oil, but GM requires you to use it when installing a GM crate motor to validate the 3yr/100k engine warrantee. So it’s liquid insurance. Really it’s a good idea to use whatever recommended lube in any new engine build or startup of a crate motor to prelube the engine to help ensure proper break-in to prevent premature bearing failure.
