I have been asked by the moderator to not discuss this subject without proof, so here is proof that Walmart SuperTech Full Synthetic Oils are made by Shell (owners or Quaker State/Pennzoil). Of course, this is not proof of whether it is identical to PP as some have claimed, but I am not making that claim here.

After checking the Walmart MSDS website, it appears that all grades of SUPER TECH Full Synthetic Motor Oil are now made by Specialty Oil Company, P.O. Box 4427, Houston, TX. 77210-4427. Warren apparently still distributes (or even may blend) the regular and synthetic blend Super Tech oil, but not the full synthetics.

Some posters on the following link suggested that Specialty Oil Company is owned by Shell (Pennzoil/Quaker State).

I called the Specialty Oil Company MSDS Assistance Number: (877) 276-7285 listed on the MSDS link above from the Walmart site for SuperTech Synthetic oil:

a. First I hit 1 for English
b. then I hit 3 for technical information regarding the MSDS
c. Then the voice response unit asks whether you want technical information for Shell, Pennzoil/Quaker State, or other car care products.

Then I went to the Pennzoil webpage to get the phone number for their MSDS info.
http://www.pennzoil.com/site/contact.html
The phone number is different (800-546-6227) than the one above, but when you call that number for Pennzoil MSDS you get the exact same voice response information as for Specialty Oil Company (and all other Shell companies).

Try it!

Specialty Oil Company is Texaco Lubricants which is basically just Chevron.

Texaco Lubricants Co.

When I call (800)782-7852, it says "Thank you for calling Shell...".

Shell owns Quaker State/Pennzoil

WPP still makes the WM full syn that is distributed to the North East.

All I can say is check those links I posted. They list a Texaco website.

Wouldn't Walmart have to post a MSDS for that specific product? The MSDS I found suggest that as of now, it is Specialty Oil Company. I believe you when you say it was previously WPP, but not sure about now.

I guess that things change. I would think the voice response unit that answers the phone right now would be the most accurate.

The Walmart MSDS site has WPP listed. Type "10W30" into the search and you will find them.

I found it. I wonder if they have switched to WPP, switched to Shell, or just use both?

I checked the MSDS for Pennzoil Platinum 0W-20 and here is the manufacturer listed:

Manufacturer/Supplier:
SOPUS Products
PO Box 4427
Houston, TX 77210-4427
USA
MSDS Request : 877-276-7285
Emergency Telephone Number

This is exact same address and phone numbers listed on Walmart SUPER TECH Full Syntetic Motor Oil MSDS for Specialty Oil Company. Only the company name is different:

Specialty Oil Company

Houston, TX. 77210-4427

MSDS Assistance Number: (877) 276-7285

Super Tech seems to get positive reviews from its users, thats about the only thing I know about this subject.

I have seen msds from Exxon-Mobil, Specialty Oil Company, and WPP for Walmarts oils. If you look at some of the dates on them they are pretty old so I'm not sure that particular company is still making fluid for them. I've read/heard Walmart's oils on the west coast are made by SPC, east coast Mobil, and central US WPP. Knowing Walmart I think they go with whoever gives them the best deal at the time. They put out a contract, whoever gives them the best deal gets it, and when the contract runs out they put out another and the process repeats itself. They could have a diff supplier every year for all we know.

I SERIOUSLY doubt that WM synthetic is the same as PP. If it is made by Shell then its probably closer to FS synthetic.

Maybe it's the same as Helix.

It doesn't matter who makes it, Supertech is a very good low cost oil.

It seems quite a few companies have that address.
