DEF

[Dave45]

I'm new to the diesel world. wondering if any one has had problems with the Walmart supertech DEF?  I've read more good than bad but don't want to walk home!

All I've used so far, no issues yet

I have used nothing but the DEF ($6 or $7 / 2.5 gal) from Rural King to date. No issues noted.

I've only ever used the Walmart brand with no issues.

Really, i find the requirements for DEF to be pretty clear as a mixture of 32 percent urea to 68 percent distilled water. There is no real reason for extreme high prices versus extreme low prices unless it has been tampered with or just a scam. Just by a known manufacture and you should be ok.
