There are kits for bypassing the need to use DEF, but probably illegal. Choices will have to be made.

DEF is made from Fertilizer. The railroads have have significantly cut off Fertilizer shipments to farmers and DEF manufacturing facilities. Planned implosion. All modern diesel trucks run on diesel exhaust fluid ( DEF )

Where It Comes From

The most common types of urine that people think go into the making of urea for DEF – urine from cows and bats, which is not correct. Contrary to popular myth, cow and bat urine and DEF are not a thing. The urea used in the manufacture of DEF is synthetically derived from ammonia and carbon dioxide, and urea production plants are often adjacent to other sites where ammonia is produced, such as coal and natural gas refineries. This allows for the capture of hydrocarbons from ammonia plant feedstocks to be used in the manufacture of urea, rather than allowing harmful emissions to enter the atmosphere, and eliminating the need to purchase ammonia as a separate commodity. In short, it is easier and more economical to manufacture urea on-site or nearby where ammonia is already being produced.

this internal war has been in the works for some time now, consider why this could even have become required knowing what we know now and the current events, could DEF have been implemented from the beginning to bring trucking to a halt, this shit was all planed many years ago imo

DEF delete it can be done.... My husband has done it

30 mins and a computer to get rid of most def systems. Not the end of the world. But will they… probably not they will get paid not too.

Big tractors need it too

It’s the railroads that are causing the shortage. I watched a senate hearing where the ceo of the largest def fluid company payed it all out there.

Looking it up, def is just piss and water... Might be able to use distilled water.
