Can I add AdBlue myself for our GLE 300d?
My wife has a 2016 GLE 300d. It has almost 40,000 miles on it and seems to drink AdBlue every 7 - 8k miles. It's pretty inconvenient and expensive to go to the dealer every time it needs AdBlue. Does anybody have any experience with topping it up with generic DEF? The dealer of course makes it sound complicated and I'm sure it's not, but figured I'd get some input here first. Any help is appreciated!

Good approach. I just cut the bottom of that expensive bottle and using it as funnel.

That certainly went up! 
Remember, DEF is DEF. So you have several options from Walmart, to AutoZone, to truck stops. The only thing you really "need" is the neck from the small MB bottle that you're using as a funnel.
