How do VII's work? The simplest answer is that they cause the viscocsity of the total oil package to increase in viscosity as the temperature rises, and effect the oil very little at lower temperatures, thus preventing the oil from thinning out of its multiviscosity grade when temps rise.
So how could Valvoline Synpower Oil Treatment have a negative effect on the CC and pour point if the Synpower additive acts as a VI improver ? I would think that cold weather performance is improved. yes? , no ?quote:
One has to not only consider the 100 C viscosity, but the thickening effect at 0 F. I suspect it would raise CC and pour point somewhat as well.
