Is that supposed to be funny?
More meant to be silly. But there is a line to "saving money" on fluids and lubricants.
In the early days of DEF the bill in our shop for correcting and fixing HD trucks coming in with out of spec DEF in the system ranged from $3000 to $6000 depending on what had contaminated the SCR system.
When a vehicle arrived with codes and a complaint the first step was to draw a sample of the DEF on board and test it in the presence of the customer or their rep.
Non warranty "Operator errors" consisted of adding distilled water to the DEF tank, adding tap water to the DEF tank, adding human urine to the DEF tank, adding what should have been proper spec DEF from an unsealed "cheaper" bulk source, using stolen "DEF", adding home brew DEF - these sorts of things.
It didn't take long for word to get around on the bush telegraph contaminating DEF as a cost saving measure was not good economics. The absolute hardest working Paccar trucks with either Cummins or Paccar power (like 140,000lbs GCWR) would use DEF at around 1.5% of the rate of fuel burn (1.5 gallons per 100 gallons fuel) so the "savings" of all the DEF schemes didn't amount to much vs repair orders. In simplistic terms DEF consumption is a function of NOx emissions which is a function of high exhaust temps which is a function of engine load/fuel rate.
Anyhoo it didn't take long for people to figure out to buy DEF from reputable sources.
