Ram 3500 MPG test
The Ram MPG test video. Wasn't expecting that big a difference.

When you don't produce that many engines your exposure to issues is far less.
In that case, the Cummins 6.7L is by far the most produced engine out of the three.
I'm talking about engines that went into trucks with all the emissions equipment that we drive.
I am also talking about on road trucks with emissions equipment. It is the same engine down the same assembly line using the same kind of emissions requirements/equipment. Ford, Peterbilt, Kenworth, International, Freightliner, and Ram all used the same 6.7L engine but with different tuning depending on application. Just about every diesel Ryder and Penske box van you see has the same Cummins 6.7L.
Heck, even the PACCAR PX-7 "proprietary" engine is the same 6.7L Cummins engine but with a valve cover that says PACCAR on it instead of Cummins. Also, if you see a school bus with a diesel, then there is a 95% chance it is the same Cummins 6.7L. They even ship them overseas to be used in European markets. When it comes to on road truck diesel engines currently being produced, there is not one engine that even comes close to the Cummins 6.7L production numbers.
As of 2012 Cummins only produced 2 million engines for Dodge/Ram. I'm sure Duramax was low build quantities too.
That is just for Ram. I am talking about all on road Cummins 6.7L that share the same parts and emissions requirements that were built for trucks
(like the F650/750, Freightliner M2, International MV series, Peterbilt 337, and Sterling Bullet) and buses(like the Thomas Built C2, Bluebird Vision, and IC Bus CE). If one wanting to get a true failure rate versus total produced, those would be counted as well since they share the exact same parts and requirements.
