Has anyone used the Wal Mart brand Super Tech DEF? If so, opinions?

Haven't used WAlly brand but I did use another cheap brand. I got repeated check engine lights for insufficient catalyst on a run to Minnesota and back. After that I drained the DEF tank and refilled with Peak Blue DEF. I haven't had a CEL since then.

It could be coincidence, but the few $$ savings isn't worth it to me now.

You either got old DEF, or DEF that was replaced with water. It had NOTHING to do with the brand.
ALL DEF is EXACTLY the same.

Yep, most likely old. The box was unopened so age was the most likely culprit. Like I said, it could have just been coincidence or some other factor. But, the track record I've had with Peak, the absence of issues using it, and the minimal cost difference doesn't make the cheap stuff worth the risk.
