DEF Sale
Not sure how wide-spread the sale is, but Caterpillar near me (Milton Caterpillar in MA, NY and I think VT) has 2.5 gallon jugs marked down to $7.75/ea. Cheapest I've seen, they're normally $10/ea. Sale runs to the end of September then they go back to $10/ea. Check the date codes though, the first jug they tried to give me was old but they swapped it to a fresh one (I don't think the part picker knew any better). I just learned that Cat sells DEF through their parts counter and it's a lot cheaper than picking up BlueDEF jugs at the local auto parts stores.

You can buy DEF at Wal Mart for approx $7,78 for 2.5 gallon. Many on here use their Super Tech store brand.
I am of the opinion that DEF doesn't go bad and the date on the jug is misleading. I have carried DEF in the tool box of my truck for upwards of 4 years before I used it. The truck tool box in the the sun and heat of the sunny south here in Alabama. I experienced no issues when I used it. I have also had opened containers of DEF on the shelf in my shed for 2 plus years that I have used with no issues.
Others may disagree with me and that is fine. I am merely stating my DEF usage with no issues or "old/out of date" or opened containers.

I'll have to keep an eye on Walmart, I wouldn't have an issue running their house brand stuff. I guess the Cat stuff isn't really that good of a deal then. Don't mind me, carry on.

I'm new to diesels and DEF so I sort of 'self educated' myself on that stuff and there is a lot of conflicting and misleading information. The stuff you kept for a long time or in high heat, did it stay nice and clear for that long? Honestly, the get brought out the jug at Caterpillar, I noticed the date code so he just gave me a newer jug no questions asked.

Pugga, there is nothing wrong with wanting "fresh" DEF and see nothing wrong with asking for it. I was merely talking about my experiences. Each of the members have different opinions and outlooks so, take things with a grain of salt and do it your way in the end.
One thing I would suggest you make the golden rule for you and your truck....
NEVER, I mean NEVER open both diesel fuel filler and the DEF caps at the same time. I am not sure where the DEF fill is on your truck but the 2011 to 2016, they are next to each other behind the fuel door. Also, If I need DEF and since I do not fill the DEF from a pump at a truck stop, I pull away from the fuel island before I add DEF at a fuel stop.

Thanks for the input guys, good to know this stuff isn't as finicky as some have made it out to be.

I use the Super Tech brand from Wal-Mart. I buy 2 or 3 2.5 gal. Containers at a time. I keep mine in the closet where the basement stairs are. I never look at the date stamp. Just put them in the cart and buy them. I just make sure the seal on the jug is secure.
In case you haven't gotten one, buy a Ford factory DEF nozzle to prevent a mess.

There was a time when this wasn't the case, and I believe a lot of people are a bit "older" and are of the mindset that it's better to have and not need, than not have, and need.

Huh... I bet there was a time people said that about toilet paper and ammo too. Yeah I know DEF ain't ammo but you get the point. At no time did I ever had more than 3 in the closet. I usually need it and use one so usually 2 jugs in the closet.

I always have fuel and propane on hand... Not a few hundred gallons but enough to get my going if I'm ever really in a pinch. I don't do it with the mentality of dooms day preparation but we do get storms that sometimes take a bit for businesses to recover. My generator runs on propane which is the reason I have that on hand at all times. Just being prepared and a lot of times you may not necessarily know what you're preparing for.

Yeah, my DEF is stacked up...
I do have plans to upgrade my stock 26 gallon tank for S&Bs 56 gallons. Not the hundreds you're talking about but it'll do.
