The Super Tech branded stuff was marked(obscurely) as an "Ashland Oil" product. I know nothing about Ashland other than their coal exploits in Kentucky. Just FYI.

I wouldn't be surprised if numerous suppliers fill Super Tech bottles depending on which masochistic company submits most readilly to WalMart's desire to whip any given market into complete submission.

I hereby offer an oath to you all that I will not get into the detrimental impact of WalMart's business practices on this board. There's not enough time or bandwidth to choke it all out.

I use Rotella exclusively in all my Diesel Benzes. The gasser gets whatever is on the menu since it burns enough, and gets topped up enough, to always show honey clean oil on the dipstick. Anyone want to grant me the time to change out the valve guide seals on a M103?
