Project Farm is a sponsor-free, auto-tech/engineering review channel on Youtube.

They're known for testing products you may have come across like amazon oil vs valvoline, seafoam vs techron vs mmo, etc, but also fun, goofy stuff like 3D printing cylinder heads, JB welding rod repairs, bacon grease for fuel and so on.

Now I recognize this forum's general antipathy toward additives, but found the Engine Restore test, and follow up one year later, quite interesting. And low and behold, there's even a compression test.

Thoughts?
