2012 and up Cascadia

Cummins fixed most of their EGR valve issues.....most of them. Still happens some. Cummins seem to burn more DEF in our fleet, and to me feel less powerful when they are supposed to be spec'd the same. Both need a new DPF around 500,000.

, they're giving him a ride alright

 

I don't know if it is isolated to detroits. Idling these EPA10(+) trucks for extended peroids of time is problematic for the engine and probably more so the aftertreatment systems.

 

That is a toss up.

Had a '13 Cascadia with a Cummins that was plagued with electrical demons. Had a '13 with a DD15 same program never an issue.

Next program had it exactly the opposite. The DD15 was a nightmare and the Cummins ran like a champ if a little weaker.

I would suggest looking at records for individual trucks, than relying on a blanket statement about Cummins V Detroit.

All trucks are like that. They require MAINTENANCE, it's not a one and done type of thing. You have to look and poke and prod and wonder,"what if?"

 

Stay away from any Prostar with the Maxxforce engine.

 

I would buy a truck with Cummins cm2350 . before buying it top cover must be taken off and camshaft must be inspected. if its not worn then it means truck was not on 50k oil change interval. I would replace fuel pump's plungers every 350k miles. it's much better engine than dd15. my friend has them and only nox sensors have been changed on trucks and dpf filters in past 3 years.
