Who manufactures Walmart's SuperTech antifreeze?

Answer 1

I did my own personal research on this question, and studied the Supertech Extended Life (5 year/150,000 Mile) Antifreeze bottles stocked at a local Walmart in Austin Texas. I compared them to the bottles of both the Peak and Prestone Long Life brands that were on the shelf next to the SuperTech product.

Here's what I observed:

1. The Prestone bottle shape is unique and different than the Peak and SuperTech bottles.

2. The Peak and SuperTech bottle shape is identical.

3. There is a lot number printed near the bottom of each bottle on all the antifreeze bottles I looked at. The Peak and SuperTech bottles had lot numbers that began with a C followed by a long string of numbers, which were nearly identical. The Prestone bottles had a totally different lot number format.

4. Both the Peak Long Life and Supertech Long Life bottles listed the exact same ingredients, including the NJTSRN QT1 mystery ingredient(s) that evidently Peak doesn't want us mortals to know about (It is the same ingredients found in DexCool, which some folks claim will rot the insides of your cooling system!). The Prestone Long Life bottle does not list this mystery ingredient.

Here in Texas, I would bet that the SuperTech Extended Life antifreeze is currently supplied by Peak. Could be a different story in other regions of the country, but do a little investigative research at your local WalMart next time you're there, and see if you observe the same things I did.
