If I send the wife to Walmart to buy me a $9 container of DEF it will cost me between $80 or $120 for sure.

I agree. I buy my DEF at the dealership so if something goes wrong and they say it's was cause buy the DEF I will say I bought it here.

I think as long as you inspect the jug before filling, you're going to be fine. Unless the dealer is putting it in for you, buying it there doesn't change much. Who's to say they wouldn't sell you expired DEF? I'm sure they have a pretty decent turnover of the stuff, but it's possible, and if you filled just assuming the dealer stuff must be good, it's still your fault. I have used the Air1 brand since I got my truck, always from Walmart or CT. Never had an issue, well actually a P20EE, but that would have happened anyway. Clear jug with a disposable nozzle, inspect the jug and you are good to go. Also if you look hard enough on the box there is a production date somewhere, if you are that worried about it.

DEF is DEF unless it's begun to crystalize due to storage in high heat and/or evaporation. I don't have a truckstop near me, so pump dispensed DEF is unavailable. I've used Peak & Mopar brand DEF so far. Who knows what was in the tank from the dealer as they never filled it prior to delivery.

I checked out the Super Tech at Wal-Mart, but didn't buy it. I could not find the ISO certification, although it listed the correct concentrations. Just didn't feel comfortable saving $6 or $7 vs. the Peak brand. Maybe I'm just being paranoid?

Super tech products in general make all of us paranoid yet for no reason. Case in point I would never put super tech oil in my "nice" cars but I've been using it in my 96 Jeep for 8 years. One day I realized that. 8 years, super tech oil. No issues.

Due to the sensitive nature of DEF relative to age and degredation, I can't help but wonder if there is a recommended volume interval for adding it. In other words, is it better to wait for the tank to empty (meaning that the age of the DEF will be extended) as opposed to adding it in smaller increments, say adding 2.5 gallons when it gets to the half tank level on the gauge (which means there may be a mixture of old and new DEF in the tank). Thoughts on this ??

DEF in my area has gone up in the last year. The last that I purchased was on AMAZON, $33.00 for 6 gallons of CAM2 DEF. That was the delivered price for Prime members so at $5,50 a gallon it wasn't too bad. The last Peak that I purchased from my local Auto Zone was starting to crystallize and it was 19.99 for 2.5 gallon. At least the AMAZON was fresh and a better price. Another thing about the DEF. I had my truck serviced last week and asked the dealer if they had any ECO Diesel problems coming in for service work. He said only the ones whose DEF clogged the DEF injector. I asked how that happened and he said the people did not drive them enough!

I just picked up one of our work trucks that was in a local diesel shop. The owner told me "don't use bottled DEF if you can help it". He said it goes bad way too fast. Truck stop big rig DEF is going to be the freshest & most economical way to go. I try to hit a truck stop if I drive near one - so far, so good. We don't have anyone that sells DEF at the pump where I live.
