And I quote
"Off road diesel is designated only for vehicles and equipment that do not operate on public roads and highways"
Operated on. Not transported.
Because of no road tax. It's the same diesel, just has die in it. Engine makers don't know whether that engine is going in an on road or off road application, they don't make 2 different engines, 2 different fuel systems, or 2 different head set ups for on or off road engines.

Follow the money, off road fuel is the same as on road fuel, the only difference is one has a road tax attached to it and the other doesn't.

I beg to differ.
Ultra-low sulfur diesel was proposed by EPA as a new standard for the sulfur content in on-road diesel fuel sold in the United States since October 15, 2006, except for rural Alaska. California required it since September 1, 2006, and rural Alaska will transition all diesel to ULSD in 2010. This new regulation applies to all diesel fuel, diesel fuel additives and distillate fuels blended with diesel for on-road use, such as kerosene, however, it does not yet apply to train locomotives, marine, or off road uses. By December 1, 2010, all highway diesel will be ULSD. Non-road diesel transitioned to 500 ppm sulfur in 2007, and to ULSD in 2010. Locomotive and marine diesel also transitioned to 500 ppm sulfur in 2007, and to ULSD in 2012.

High sulfer Diesel also costs them less to produce as it doesnt have to be refined as much.
Whats a good additive?

Trucks made in 2000 and after don't need additives, the engine manufacturers new the fuel standards were coming and developed their systems accordingly. If you're driving a diesel built between 82 and 94 1/2 then the systems have most likely failed and been rebuilt with better parts and a good additive for the older diesels is stanadyne lubricity and stanadyne performance additives.

Never used any of the snake oils, have diesels ranging from mid 70s to a few years old.

They don't need additives to run and possibly for a long time. The stanadyne additives were developed to put some lubrication back in the diesel because the sulffer (lubricant) was reduced greatly.

it won't hurt. If the truck is newer than 2000, it's not needed

You have to be careful, diesel is dry, sea foam is a detergent cleaner, today's injection systems have fuel pressures of anywhere from 20,000 - 45,000 psi, excessive cleaner use can shorten the life of injectors. Injectors in today's diesels can range anywhere from $700 - $1800 per injector, plus time and parts for the R&R

I just bought a 2018 Ram w/Cummins . How is this supposed to regenerate? Park brake needs to be on? I know nothing about this?

All the trucks from 2012 and newer, go through a cleaning or regen process while you drive automatically. If it is stationary and has a lot of idle time, it'll do a cleaning in park idling. Park brake is not needed. There should be a message that comes up on the data display on the dash that says something like cleaning exhaust filter. When it's in the cleaning mode, you should try to drive it to complete the cleaning. If you stop and shut the engine off, it'll restart the cleaning when the truck is restarted

There is no message on a Ram during normal operations. That’s either passive or active regen.

Yes it will. That’s active, when adding fuel to raise temps in the filter comes into play. Additionally, in the case of a plugged dpf the dealer can initiate a prolonged regen but it requires a dealer scan tool as far as I know.

I just got a 2018 Ram w Cummins and I dont know when it regens how or what to do? does the park brake have to be on like my Ford F750? How long can the blue DEF fluid sit in a tank before going bad?
