Get DEF wherever it is cheapest or most convenient. The composition is spelled out in Federal regs. There is NO allowance for “secret sauce” or any amount of deviation. It’s made of two of the cheapest compounds known to mankind, so incentive to make it cheaper is lacking, as well as outright illegal.


Correct; unlike motor oil, there is no good/better/best, it must meet a standard and it's all the same, like buying isopropyl alcohol at the drug store.

Buy the cheapest you can find. I use the WalMart SuperTech house brand at $7.88 per 2.5 gal jug.

I've used the truck stop in the past and with the small amount I use, it's just not convenient for me.

DEF can also be found at Class 8 truck dealerships, construction and ag dealerships.

Those industries haven’t figured out how powerful and efficient new gasser engines are [emoticon]

Yes.

I also always keep a couple jugs of DEF from Walmart in the bed of my truck. Their prices are hard to beat. I remove the spouts from the jugs and put those in the back seat of the cab, because they poop out in the sun.

It supposedly has a 6 mo shelf life

I never buy unless I’m getting low.

In 52000 miles all DEF has been Peak Blue DEF all but one from Wally World. The one not from WM was from a Loves truck stop in the middle of NV.

Our local WalMart goes through A TON of their DEF so it's always fresh.

I keep a jug of Blue DEF in the spare bedroom. Because, it degrades with heat and sunlight.
According to Cummins

Q. What is the shelf life of DEF?
A. The shelf life of DEF is a function of ambient storage temperature. DEF will degrade over time depending on temperature and exposure to sun light. Expectations for shelf life as defined by ISO Spec 22241-3 are the minimum expectations for shelf life when stored at constant temperatures. If stored between 10 and 90 deg F, shelf life will easily be one year. If the maximum temperature does not exceed approximately 75 deg F for an extended period of time, the shelf life will be two years.

Our local Mobil Circle K has both auto diesel pumps and and at the truck lanes they also have both diesel pumps and and unleaded pumps for Rv's and motorhomes and vehicles pulling trailers also they advertise DEF 2.59 a gallon and has been that price since they opened 6 years ago. And I forgot to mention that the RV Lane is the outside lanes so you don't block the big rigs and I've even used it when I was going camping it's on the way out of town near the interstate.
