Why aren't they made to same specs as the name oil from the parent company?
And since when do the car manufacturers become experts at oil to the point of asking the oil companies to make an oil for them with these additives, etc? Would the oil companies themselves know better?
So is the motocraft not as good as the Conoco now since it was made FOR Ford vehicles? I just bought a case of it because I thought I was getting Conoco Hydorclear in an area where Conoco isn't itself sold.
More to add to the confusion of selecting an oil...
I may start using Penzoil exclusively. Besides Conoco and Penzoil, what other oils are Group II+? At least Penzoil can be bought *anywhere*. And I am sure Penzoil has terrific R&D $$.
But now Shell is buying Penzoil. Good ole american motor oil with long history getting bought by Dutch petro company. Will they then change Penzoil to start using their formulas, which were once Havoline? Ugh.
Never knew how much confusion was in the oil industry till I started looking.
