I have never been entirely sure how something can be deemed non-toxic and yet corrosive at the same time.
Salt water is non-toxic but does a pretty good job of corroding iron.

Do all DEF containers have a pour spout? I purchased a Blue DEF container from a Tractor Supply store near me and it didn't have a spout. It seemed odd that it didn't.

Salt water most certainly is toxic. If you don't beileve it try drinking a gallon or two.

Just bought def from AutoZone:

Twice in the last 6 months I purchased a 2 ˝ gallon container of “Blue DEF” from 2 different Wal-Marts and the container was filled with water. The first time I purchased it while traveling and when I went to use it DEF there was no seal under the cap. I smelled and tasted it only to find it to be good old H2O (water). From this point on I check to see if it has a seal under the cap. This past Monday I purchased another container and checked to see if it had a seal, it did. I took it to our RV and when I went to pull off the seal it came off with NO effort. Checked the contents and found water again. This time I was only a few miles away from the Wal-Mart where I purchased the DEF and returned the container. The manager and employees had no idea what DEF was and told me that people do return saying they purchased too much. I told the manager, if a person purchased 5 gallons of gas from Wal-Mart and came back to return it saying the purchased too much would you accept the return? He said NO, how can you buy too much gas! I told him the same thing goes for DEF, you can’t buy too much, and it will be needed and used if you own a diesel engine vehicle that uses DEF.

This post is only a caution so I do not want to start a long thread about where and how to buy DEF or who does or doesn’t shop at Wal-Mart. However please comment if you have experienced the same problem with buying DEF at Wal-Mart.

Just a note from tnmurp: Just yesterday I bought a box of DEF from AUTOZONE for my Cummins diesel. I had the Cummins number out of the Cummins spec. book and other requirements/information that the DEF should met. The store manager and I checked the numbers and the shield/badge on the box and all were in order. The DEF was in a sealed box except for a hand hold. It also was a fairly good price. Just saying.
Oh, but they only had the oil I wanted in 2 gallon size. wanted just a couple of qt's for spare if needed.

Anything we buy in ANY store we always check the seal under the lid!

We do this because when we opened our new jar of Nutella there was a 'kid size' finger hole in the seal!!!
