I have a 9l Cummins engine in one of my vac trucks and it has all the new environmental systems such as dpf, def, soc, egr and Jesus it is a nightmare. It burns more fuel, pumps hot exhaust gasses back into the engine causing soot buildup in bearing orfaces, super hot engine temperatures, major fuel consumption issues and just got a quote of $2000 to clean the dpf filter and replace urea injector. Probably another $3k in other related repairs.
So for doing the right thing I make less money, have more downtime, and pay more in repair and fuel. On top of that, the government is raising fuel taxes to make it make even less sense. All of my competitors must be laughing thier ass off at me.
It is about $10-15k to tear all that garbage off, and could spend double that putting it all back on if the government decides to mandate it by tying it into your cvip.
Pretty much sums up the problems with the world perfectly IMHO. Do the right thing, and pay severely...
