Looking at the 5w30 PDS numbers for this oil on the Castrol site shows a VI Index of 149. Should this considered a good figure or bad:
Good because it uses less viscosity improvers?
Bad because it indicates low quality base stocks?
I'm not asserting either suggestion as fact, just interested in the plausibilty of each.
