He said “DEF.” I asked what DEF was. He said “Urine!” Soon after I googled it to learn it was urea. He was sort of close I reckon. Lol

Used by the Selective Catalytic Reduction Unit (SCR) in your exhaust to reduce oxides of nitrogen (NOx) emissions. NOx is one of the pollutants that helps form smog or ground level ozone, a known respiratory irritant. The urea is metered and mixed in the exhaust which then goes across a catalyst. As it goes across the catalyst, chemical reactions occur that break down the NOx to nitrogen and water vapor. Most new power plants and many other combustion processes (boilers, heaters, furnaces, reformers, diesels) all have SCR systems.

He drove it down to Oklahoma and around, wife and daughter borrowed it to go the UP here in MI for a hockey tournament. While they were up there, I asked my dad when he filled the DEF last. He asked me "what's that?" Called the wife and told her to buy a jug.

He should have known but in his defense, those new trucks with the 3 liters really are soccer mom trucks. Nice trucks but not made for heavy work
