High-Performance Engine Lube for Smooth Assembly
I was initially surprised by the size of the 4 oz. bottle, but don't let that fool you - a little of this engine lube goes a long way. As I appkied it, I was impressed by how effortlessly it coated the engine parts, promoting a perfect fit with each piece. This high-quality lube pplayed a crucial role in reducing friction during assembly, simplifying the entire process. Additionally, the vibrant red color not only adds a fun touch but also serves a practical purpose by clearly indicating where it has been applied, preventing any areas from being overlooked.

This stuff stays exactly where you put it at. You don't have to worry about it running off of what you put it on.It has enough of stickyness to stay in place.

Great for rebuilding valves.
This stuff is great. I used it when installed new valves in my Subaru and it was like magic. It made installing the retainers super easy. A little bottle will last you a long time too! Great stuff!

A Quality Lube!
Permatex is a well known name in the automotive industry. I needed some assembly lube for my distributor gear because of a swap. This was priced right, very easy to use. This is the right size bottle for my needs. This is a good quality lubricant.

How real it is and the reviews prove it!!!
I’m certainly impressed and convinced that it’s the very best available for rebuilding engines with the description of it better as slick like “ PIG SNOT” must be either Arkansas or Mississippi!! I love it and that’s absolutely correct!!!!!! X trillion plus you go, man. Arkansas because the “hogs” and ‘“Sippi” BECAUSE OF REBELS!!!! Both are great places!!!!!!!
