I hope I get all of this in the right order.
Chris: Warren distributes to some of the Wal-Mart stores. But they do not make the product.
csandste: Where to begin. The main difference is base stocks and additive packages. All Pennzoil basestocks come from the new refinery in Louisiana. This refinery is co-owned with CONOCO. All Pennzoil motor oil is either a Group 2+ or Group 3. The additive package for these products is propriatary to Pennzoil only. Quaker State base stocks are purchased from Exxon and are a Group 2. The additive package is pretty much standard industry specs. I know the specs on the SuperTech look close to Quaker State when new, but I believe you would see a difference when tested at 3,000 miles. They use different basestocks and additive package.
As for as I know, the SuperTech oil is the only private label oil that is made by this division.
Wolf's Head oil. Wolf's Head is a 125 year old oil company that begin in Oil City, PA. Same place Pennzoil and Quaker State started. About 12 years ago, Pennzoil bought Wolf's Head, but ran it as a seperate business. About 5 years ago, Wolf's Head was made part of Pennzoil and used as a price fighting oil. Since Pennzoil and Quaker State have become one company, the Wolf's Head is made at two blending plants. A Quaker State plant in Virginia and the Speciality plant in Louisiana. If you could run a test on this product from the two different blending plants, you would get two different looking spec sheets. Mainly basestocks and additive package. They are all very close in specs when new, but again, look at them at 3,000 miles. I have probably forgotten something, but I hope this helps.
Oh, I forgot one thing.
widman: I don't know much about Chevron passenger car oils, but I do know the Delo 400 is an excellent diesel oil.
