Standard issue
Lovely sticky slick engine lube. Great tack adherence. Pretty much the benchmark if building a fresh engine.

Perfect helped make my new engine installation go smoothly
Brought this to use with my new engine on my car, i'm not a professional mechanic but this stuff is very sticky, over the course of a few weeks I built up my new engine and once applied this stuff stays in the area you left it. Fast forward the engine is in and running, no issues and after the first oil change there is no signs this stuff was ever in the engine which is what you want.
