I do agree. Unfortunately most manufacturers of diesel engines aren’t stoked about environmental regulations and plenty have stopped trying all together.
Currently their plan is to just throw more urea at the exhaust.
I remember them having to bypass the DEF system on a lot of vehicles because they didn’t make enough spare parts of the system they put in. So I’m sure they knew either face public backlash or get fined by the government. It was probably a calculation where the 2b was on the cheaper side from them. I’m sure they made enough money that they don’t feel the need to fight it.
Once again, not an endorsement. I’m sure every diesel engine manufacturer is/will/was doing the same thing.
I went to visit a friend a few states over for their wedding. They let me stay at their place for a week. For the time off I work union :D
