def
Being a new diesel owner I was curious if there is a difference where you purchased your def or if there are different brands, good and bad?

The magnets are required at some Loves truck stops - the last time I went through Kingman, AZ that one needed it. There are also some BLU stations in Utah and other states, and the last one I used in Hurricane, UT needed it. $2.669 was the last price I got there for DEF.
One bad tank of DEF can cost many times more than that little savings.
I don't see the risk reward ratio being favorable for the cheaper DEF.
YMMV:)
Never really looked at it as a "risk" or a "reward"....I was "given" a 2.5 gallon box of DEF the day I picked up my truck, May 9th, 2013...after it set for over a year, I got rid of it.....date had expired...didn't cost me anything, so I didn't lose anything....I had actually forgotten about it....DEF is DEF, Blue DEF is Blue DEF...it's the same as what's in the box...To me, it's more "convenient" to drive to the truck stop and pump it when I need it....Nothing "cheap" about it...again, same thing as in your box....The DEF I'm getting is just as pure as the DEF you're getting...(sorry, it IS the same thing)...and as much that is used at the truck stops, it too is "fresh" and not "out of date"...almost 28,000 miles, zero DEF issues....
One could get a bad 2.5 gallon jug just as well as one could get bad out of a pump....thus, that too could be costly..
I've heard of zero issues with the 2.5 gallon jugs, and zero issues with DEF being purchased at the pump, but that's just almost 2 yrs come May 9th.
The fact is that buying from the pump IS riskier. Did the guy before you get some diesel or other material on or in the nozzle somehow? Have you ever looked inside a nozzle before pumping? I have on the diesel pumps, and on more than one occasion decided to go elswhere.
And yes the truck stops do go thru a lot of DEF. But they buy it in huge lots, and you really have NO WAY of knowing just how old it is.
It is not sealed, and you are trusting the minimum wage personel at the station to do everything right. That is another possible source of contamination. When they switch storage tanks, they can introduce dirt, oil etc into the tank or hose.
I find it very easy to get the 2.5 gallons at Walmart. Sealed and date coded means I have a much better chance of not having problems...
And BTW, I have one of the first GMs made with DEF My 2011 was ordered and delivered in 2010, and I now have over 40K on it.
Since I have more time and experience than you in this, does that make my opinion more valid? Of course not. I did state that YMMV in my post.
Everyone has a different take on risk reward ratios. I don't jump out of perfectly good airplanes just to see the parachute open. I see that as a unecessary risk. The plane is more likely to land without a problem.
Others love doing it. It's a free country. Do what makes you happy
