Is low sulfur diesel gonna lower the performance or quality of the fuel?
No, it will not affect your car's performance. The lower sulfur fuel will work with modern catalytic converters, etc., so that pollution is reduced, and so that manufacturers like Mercedes, VW, etc. can once again meet EPA emissions requirements, enabling them to sell the same excellent diesel-engined models here in the US that they have been selling in Europe and elsewhere all along.

As far as the pump nozzle not fitting in your tank... It has nothing to do with the car being a 1985, or anything of the sort... You were just using a "truck" pump, which is perfectly fine.

It's the same fuel....

The difference in "truck" diesel pumps -vs.- "normal" diesel pumps is that the "truck" ones pump fuel at a much faster rate, for obvious reasons... most large commercial trucks have large, high-capacity fuel tanks.

This high-speed fuel delivery rate is not necessary for the relatively small fuel tank in a car, and it actually can cause accidental overflow and fuel spillage, so the high-speed truck pumps are fitted with a bigger nozzle, to discourage people from using them to fuel cars.

Regular gas stations typically have diesel pumps with the "normal"-sized nozzle, whereas truck stops have the larger-nozzled "truck" pumps, but they also usually have a couple of specifically designated "car" or "car/RV" pumps, with the smaller nozzles that will fit in your tank's filler neck properly.

The stuff that is illegal to burn in your car is "farm/off-road" diesel. It is also exactly the same fuel, but it is dyed red to make it easily identifiable. The reason that it is illegal to use this in your car is because it is untaxed. The government doesn't want you driving around on highways that you're not paying for (the aforementioned fuel tax). It is not typically found at gas stations and/or truck stops, so you shouldn't need to worry about accidentally putting it in your vehicle.
