good sir, i believe sopus owns both Pennzoil and quaker state. so im betting both are very similar to each other.
That may not be the case. In the past Quaker State has used Ornite VI's and additive packages for Quaker State products.
Where in the past Pennzoil has used a VI packages from Shell and whatever individual additives bought from Lubrizoil, Ethyl, and Ornite that made the best formulation possible. Shell/Pennzoil has traditionally spent considerable resources in maintaining Pennzoil as the flagship brand of SOPUS.
If this is still the case someone would have to contact Shell and see if Shell still wants to make this information public.
