That is true for conventional oils, but not nearly as much so for synthetics. Castrol, in fact, is the only synthetic that does not use any viscosity enhancers at all, the viscosity range is a "natural" property of the PAO fluid used, and Castrol has a way of producing it without using typical viscosity range additives. There was a great SAE tech article on this I have to dig out at home and post somewhere. ===== . |
