This is why some Group 3 products perform as well as some products that are touted as Group 4 or 5 when in fact they contain very little of either. And, they are much cheaper too

Carrier Oil
Oil (Petroleum), usually solvent neutral (SN) or process oil, used to "carry" or dissolve and/or disperse additives, which would otherwise be too viscous or even solid, and therefore not easily mixed with the Base Stock Oil.
