Below is a concentrated VII, a Viscosity Index Improver. Specifically, this is an Olefin Copolymer or OCP. One of the early VII's and mostly used with economy Group II mineral oils and found in aftermarket off-the-shelf-additives to thicken oils. It is very 'shearable' and is not much used in modern oils. Viscosity is about 150 cSt and amber colored. Modern VII's are more shear stable, especially the one's with the 'Star' molecule structure.
Below is concentrated ZDDP ester which I can use to boost ZDDP levels for racing oil applications or for "run-in" oils. It is black and about 25 cSt.
