i could be wrong but isnt dodge advertising that the 2011 trucks DO NOT use DPF??
was looking on all different websites camparing the new d-max and the new stroker, and one big advantage was that dodge did not use the DPF?

 

That would seem like a candidate for fuel dilution, and absolutely the wrong thing to do - just load up the DPF even faster. I believe the way this "supposed" to work is, they inject a very small bit of fuel on the exhaust stroke, so it burns in the DPF. I still don't see how you blame regen for fuel dilution, unless the amount is out of adjustment way too high for some reason so it is washing down the cylinder walls. That would be very bad for the oil and the rings.

The old standard leaking injector(s) is always a good candidate for this problem, anyway.

 

That was Polly DEF, diesel exhaust fluid, not DPF. The 6.7s very much has a DPF.

 

Only the EPA would come up with injecting **** into the exhaust to reduce emissions.

and thats a clean egr i have seen them 10x worse then that

 

I was just totally speculating, it could be the other way around. I know in theory it shouldn't effect the oil level in the engine but in practice I think it is far less successful then they hoped. I know with the Fords it is VERY common for the 6.4s to "make oil." Could just need to reflash to get the fuel amounts in check. There is a TSB floating around somewhere that Ford claims up to 4% fuel is acceptable.

I can only imagine how nasty a 200k mile EGR looks...

 

That's what we initially thought was a leaky injector but doesnt sound like it anymore.

 

I recently pulled up a video, don't recall address, on dpf filter. Went to the old timer in diesel engine building, guess the dpf sensor goes off, dumps fuel into the dpf, burns it off at around 1400 degrees, then dumps the waste into your crankcase. Some engineer was thinking there, huh? He suggests if you don't do the deletes change your oil as as possible after you get the regen message! and most drivers will have to replace the filter between 40 and 80k miles at a $2500 dealer cost!!! The savings in fuel and that savings alone paid for my tuner, parts, deletes, new shocks, springs, and other upgrades. I used to think aircraft engineers where nutcups but apparently the company I used to work for didn't hire all the lame brain engineers, Dodge picked up a couple as well.

 

Just FYI, the engine to include emission control systems is not a Dodge thing - it's a "Cummins" thing. And an "EPA" thing.

 

I may have to mortgage the house but I have to do those deletes.
