I emailed Warren Distribution recently out of curiosity to see if they were still the ones making Super Tech (specifically the 0w20 and 5w20 synthetics) and I got the response below:
Chad,
As you have noticed, we recently changed the bottles on Walmart’s SuperTech product. During that process, we had removed the stamp we had traditionally placed on the bottom of the bottle. Rest assured, we continue to be their supplier on a full line of lubricants including the Full Synthetic products below.
