I guess that explains as good as any reasons why I can think of too. Diesel was not available with the convenience that it is today, that is a fact.
Our family started driving MB diesels in 1969. At that time, there were always diesel #1, and diesel #2 pumps at most every facility that sold diesel fuel. The wintertime mixing of diesel #1 & #2 per tank fill-up was customary. The freezing-up while driving in cold weather actually happened to my Father near Fremont, NE. in his 220D. The car was towed-in to an automotive shop, and two kerosene-fired salamanders were placed one at the front, and one at the rear of the car until the fuel de-gelled.
I don't know the genesis of Power Service additive(s) but for 35 years or so, that is what we have been using in our MB diesels. Diesel #1 I had heard was less filtered, for one characteristic. The gel-point, I'm not clear on at all, versus diesel #2.
