Why buy DEF in a box?

Y'know, we used to joke about stuff like this, but pretty soon, mufflers will indeed have bearings...

 

Below 5°F DEF pumps freeze up and stop working. It's a truck stop's dream come true. They can set the box DEF price at whatever they want and guys will buy it no questions asked.

Also, depending on where you are, DEF at the pump isn't widely available (northern Canada) and having a spare in the winter can mean the difference between life and death (if your DEF runs low because you're stuck between stops due to closed roads and run out, the truck will shut down).

 

I boxed stuff is for light duty trucks. Those pumps don’t work when filling a tank on an F-series pickup. At least they never did when I was unfortunate enough to drive them. The pump handle would keep shutting off after a few drops went in.

 

The box stuff is for all.

 

The box stuff or barrel stuff test better than at TS.

 

Must be different on the Ram. The newest ferd I drove was a ‘16 F450, and it would not work with the pump.

 

I’ve seen regular pickups fill at the def pump when I used to haul it.

I don’t recall what they were though.
