Doesn't make sense to me. How does diesel get to the oil from the DPF exactly????? The 4th injection event happens on my 09 down pipe at the DPF filter does it not?? Everything I have found shows it as such. N The fuel lines running down there would seem to support this. Seein how that is bout five feet of pipe from my motor, I am failing to believe that fuel is gonna travel backwards N up hill. To end up in my oil pan... Maybe I am missing something.... Or maybe more and this will iron itself out....

Rhino.

 

I would say there is another issue with this truck. If there's diesel in the oil it probably has a leaky or cracked injector. Need to get that checked out pretty quick. It will eat a set of rod and main bearings in a short period of time.

 

Don't need find an amsoil dealer locally to get that

The fuel going to that injector is shot into the the combustion chamber on the exhaust stroke, so you have raw fuel put in the cyclinder. Ideally all of this gets pushed out the exhaust and into the DPF to burn, but some is going to stick to the cylinder walls and wash down. It's a serious design flaw in my opinion and was done becasue it was cheaper than putting an extra injector directly into the DPF like they due in all other trucks except these light duties.
But to raise it that much seems a little excessive??? There may be something else going on there.

 

When raw fuel gets injected into the exhaust stroke then yeah, your oil can raise and be diluted. Those lines aren't fuel lines either dude. They're pressure lines for the DPF.

 

I've been running rotella 15-40 since I bought my truck, 22K and I've had no problems. Only thing I have done is an S&B intake, I tried unplugging the EGR for about 3 weeks, only thing that did for me was kick on a code, I saw absolutely no change in fuel mileage like everyone claims on here.... not sure what that's all about, I guess it doesn't make the difference they say it does.

I'm on the highway for about 30 miles each way to work and cruise at about 70 to 75, and the truck's overhead says about 17.5 to 18.5 mpg depending on the around town that tank gets and again, to my surprise I have hand calculated the mpg on every tank for 20K on the truck now.... and my overhead, is always within .1 mpg...... supposedly those are way off too.

I guess I got the only truck that actually works

my lift pump did start to weep fuel.... had to have that changed. Other then that, and once about 4 months after I got the truck the P0680 showed up (just deleted it, and ran the truck on the highway at abotu 80 in 5th gear) it never came back. I do, one day a week run the truck in 5th on my way to work... even doing that the mpg has never dropped below 17.5 average without the trailer on it.

Trailer and race car loaded up with all the stuff, it's getting a nice round 11.5.... but that's 7800 lbs and a 24 foot box behind it... I blame the wind drag more then anything.

 

I know this is funny and a dealer is wanting to make money and i dont know how true it is but they recommened using mopar15-40 due to warranty issues, they handed me a pamhlet and it read in it also about using other produsts due to chrysler not backing the warranty due to faulty oil in these new 6.7's. Any one else ever heard this before?

 

i roll amsoil

 

There mopar oil is actually Valvoline Premium Blue •Endorsed and recommended by Cummins for use in Dodge Ram Turbo Diesels. I have 16,000 on my 2500 4x4 no problems, They are alson saying I needed to change out differental oil between 15,000 and 20,000 for warranty. for $288, I told them I have never changed before with no issues

 

i run delo 15w 40w

 

mine has 166k on rotella. I personally like it best
