DEF

Time to add DEF to my duramax, anyone ever use the "Supertech" DEF from Wal mart? I usually use Peak Blue DEF. Any thoughts?

    No, because if you drank Coors Light the night before, it would be too watered down.....


    Like horse p1$$!


    No, that's LaBatt's

    Agreed. DEF is DEF. If you can get to a truckstop where they pump it, it's usually MUCH less expensive that way, than boxed.....


    Yep, just ask a truck driver with a full bladder to fill'er up!

    About 54 years or so ago I was with my grandfather and I noticed a sign that said E&B beer. Being 8 years or so old and curious I asked what it is. He said that's horse p1$$. I thought what the heck and didn't ask no more about that! Funny what we remember :)
  • Like what was posted earlyer go to a truck and pump it . That way don't have to mess with a jug.

    The DEF sold in truckstops is made from urine collected at animal shelters - stick with the Peak.

    Is there a Buffalo herd somewhere where they catch that urine to put in the DEF solution and do they roller-skate in the herd to collect it.


    LOL! There is a song in there somewhere! Watermelon Patch and Baseball Pool come to mind as well. Love Roger Miller. In the "For what its worth" department, I tried the cheaper brand once and my DEF system did not reset... I was approaching 100 miles left before limp mode when I added the more expensive stuff. The tank only held about half of the expensive stuff. The system reset and I was good to go. After reading this string I guess I will try the less expensive stuff again.

    Now you must know that DEF sold at Walmart is made from mice urine - Chinese mice no less.

    While the Peak DEF is made from North American Buffalo urine.

    So the question comes down to who's urine do you want sprayed into your exhaust stream - an American Buffalo or a Chinese mouse? :@


    I spit out my coffee reading this....gawd that is funny!!
