Genuine GM Fluid 88862587 EOS Assembly Lubricant - 16 oz.

Please note I am not using this product as directed by manufacturer. It works great for me but cannot say it will do the same for you. Some of my cars are older and develop valve noise. After using this the engines quiet down nicely. It does require repeated treatments. Like I say, it works great for me.

Seems like this is harder and harder to find. I try to always use it when breaking in new motor.

Put in new Chevy engine per suggested

Great product

I'm puting an engine together for my vintage car. This assembly lube is working fine.

This GM EOS Assembly is perfect to lube engine parts upon assembly. If you plan on storing this product long term - place the plastic bottle in a large mouth glass jar. I had a new unopened bottle drain empty. The plastic got brittle and cracked in several places. I think the petroleum additives in the lube attack certain plastics.
