Evryone always asks who makes Walmarts Super Tech Oils well here's some info i found at another site.
Exxon/Mobil has limited regional distribution supplied from the New Jersey lube plant to limited regions in the East.
Super Tech from the Specialty Oil Division of Pennz/QS has limited distribution in some of the Gulf Coast states.
And, of course, WPP supplies nationally from the Omaha/Council Bluffs location

After reading all these reviews and finding these MSDS's Ive decided to give it a try in my 2005 Silverado 5.3L V-8 The Price cant be beat for a full synthetic. It does have an API SM/GF-4 rating so id say its definitely a decent oil to run for 5000 to 7000 mi.
