"Years ago" was most likely non-DEF car.
Def is scarring everybody just like first cars on the road or first cellphones, but seem there is not much to it.
I have feeling that first models with the option had big urea tanks due to lower availability, but now where you can buy it at any bigger gas station, I don't think need for 20,000 miles tank is real.
Meaning you can put smaller tank and use the space?

My company supplies semi trucks and trailers with diesel fuel, and we also sell DEF (diesel exhaust fluid). It is very simple to make actually. You can buy the DEF powder in bulk and all you do is dilute it with water til you have a 32.5% water / def ratio.
As for modifying the DEF tank, im willing to bet that it would void the warranty on the vehicle. The DEF tank is linked with the diesel tank and that is just not going to work out. Of course, anything is possible but i wouldnt do it.
Car modifications in USA are dictated by lawyers, so you are right that legally it is not going to be easy task, but observing European market, where cars are converted left and right to propane and you can buy certified propane tank in the shape of your spare tire - I keep the faith in human ingenuity.
Well LPG is gaining popularity in the semi truck industry, you see a lot these days. However, there is one problem with that for me, propane is about $3.50 a gal where diesel is $2.40 a gal here in Los Angeles. I found these highly rated run flat tires with terrific reviews [Bridgestone Driveguard] so i think I am going to go with these tires.
In Europe propane sells for 30-50% what gasoline cost and fill stations are very easy to find, so we are talking about different Worlds.
My point is that since human ingeniuity could make propane tanks that will not take most of cargo space on compact car, DEF tanks should be even easier to hide.
Same with run-flat tires. The bad experience was with GY, when Bridgestone might be totally different story.
I just can't find value in run flats and comfort is important to us. Having cars with space for good spare, no sense to spend money for lower comfort, just to have slightly better insurance.
I understand your point, but since removing the DEF tank is out of the questions, lets discuss tires for a second. So what tires are you running since comfort is important for you ? Comfort and safety is priority number 1 for me and my family.
I have 16" Michelins on Bluetec, but don't like the ride. Don't know how much rear air makes difference on the wagon, but I just put Chinese 17" tires on it and it is quiet like an Opera.
Sometimes those Chinese brands can be very soft and smooth but not too grippy, but they are very comfortable on the street and cruising down the highway. I just switched to 19s and im running Toyo Proxes and dare i say it is even softer than my 17s.
I'm at one month on my 2016 E250 Bluetec. Wow I love this car. Ended up leasing a demo with 6k miles on it but you'd never know it had 10 miles on it. My first tank of basic driving got me 625 miles. No complaints at all so far.

Sweet ride brother , the white W212 with a pano roof is a special look.
This is what she looks like today. Lowering springs and custom 19" wheels installed.
Most of these fuel additives are snake oils.... but diesel fuel in the US is a bit different than what is available in the EU countries (ultra low sufer vs low sulfur)....

care to share your experience?
My other "car" is a Peterbilt. I swear by FPPF. Have never had any problems with gelling. A small bottle which retails for $10 is good for 250 gallons, which is just about what my tanks hold, so I go through a bottle each fill up, but that's good for about 1,200 miles. You'll use just a little bit in each fill up on your car.

I personally wouldn't use any additives unless it was recommend by MB, especially if your car has under 75,000 mies. If there was a need for it, i would presume they would let us know. Oil is a global commodity and Im willing to bet we have the same ULS Diesel here in the States (if not better) as in Europe or Austrailia.
Oh i just hit 23,000 miles. Still raving about the car.
I recently did a trial with diesel fuel additive based on the same dose levels of 2-EHN from Sandia Lab's experiments. This was a two-month trial done on a on Volvo doing long hauls from Canada to the Souther US and back. Unfortunately, half way through the trial, some of the haul-backs started changing and the weather got really cold, so the fuel economy data was skewed. But one of the key benefits observed was that the DFP regens went from 1 per week to 1 every 3 weeks. So definitely where plugged DPFs are an issue, there is a clear benefit to additive, providing it is in sufficient dose levels - where most off-the-shelf products fall short.
Regarding the quality of the diesel, it can vary from gas station to gas station because the additions are often blended in when filling the tanks. Additionally, cetane number and lubricity properties are on a voluntary compliance basis in Canada, the only real parameter that is mandatory is the ppm of sulphur. So where the base diesel is the same pretty much everywhere in NA, what actually get at the pump can be different.
The EU has a regulated higher cetane number than in NA.
So, I do use additives - one for lubricity and one for cetane number.
Diesel quality in US is always a gamble.
Even before states start to add bio, I had situation when after filling up in Vegas, my car would make additional 150 miles on the tank.
Officially Nevada is using California fuels, what for decades has high % of environmental stuff - killing mpg.
I figure out that those few times my diesel mpg went to the roof was when Vegas got fuel from Wyoming.
Same had in Reno area, where 1 station was selling G-diesel. That stuff would add solid 15% to mpg.
Still you will never get official data about it.
