A couple of months ago I changes my oil and noticed 20 quarts came out. I sent an oil analysis to Blackstone and my fuel dilution was 9.5. I called a few dealers who told me 20 quarts was impossible and that it would be flowing out of my exhaust so I called a friend who runs a Lincoln service department. His dealer owns a Ford dealer and he sent my truck there.

They told me an injector was replaced but I never got any paperwork on the service even after calling him a multiple times leading me to believe nothing was repaired.

Fast forward to this week. I changed the oil and out came 20 quarts of watery like oil. I brought my truck to the local dealer and he agreed to look at it. He called me the next day and told me that I have 754 hours and 19,100 miles meaning that I let the truck idle too much causing the fuel in the oil.

I really never let the truck idle that much because I read that "wet stacking" can occur. (Dont even know what that is) The only thing I can think of is me plowing a 4 acre parking lot putting excessive hours on it?

Would 754 hours and only 19100 miles cause that much fuel in the oil?

 

Forgot to mention that when I change the oil I first take out the filter to allow it to drain. I add 15 quarts of oil.

 

first off, 754 hours only equates to roughly 25k miles which isnt that bad. there can be fuel in the oil from the fuel system and that needs to be addressed instantly. did the oil smell real strong of diesel? if not real strong, then it could just be soot from the normal running process of the engine. when these trucks go into regen the truck runs rich and puts more soot in the oil, which raises the level more than the past diesel trucks. try doing oil changes every 150 hours no more than 200 hours and see how the oil looks. also make sure the dealer that will be working on your truck does the oil change so it is in there records.

 

I have been changing the oil at around 2500-3000 miles not the recommended 5000

 

I dont know if what was stated is true weather or not the cank case could hold 20 Quarts but i do know if it was over filled to that point the engine would have been in a limp mode, similar to what happens if the oil gets to low. The engine has a miss and you will see alot of white smoke out the exhaust.

There is know way ideling caused that much fuel in the oil. I almost wonder if you have a fuel leak under the valve cover from the previous injector repair. Its my understanding that the injector tubes cannot not be reused due to the crush fit of the high pressure injection system. Just thinking out loud.

 

I have not heard of these trucks going into limp mode because of too much oil. Can anyone confirm this?

On a side not I have been using Motorcraft 15w40 and always had that ticking noise after an oil change but this last time I used synthetic rotella 5w40 and have not heard the tick.

What is there to confirm it's a fact

I've been using 5w40 rotella T for the last four oil chnages now. The tick still comes and goes. Im not to worried about it as none of the oil samples i have taken show any thing irregular. The duramax's had the same issue when they first came out. The engines are so quiet know, that noise's that were previously drowned out are now evident.

 

Sorry for being a novice with this stuff but where in that TSB does it say anything about "limp mode?"

 

It dosent directly same limp mode, but it limits the power when the oil is over filled or under filled which is what i consider a limp mode.

 

Ok thanks for the clarification. Is it a noticeable amount of power loss or slight and do you happen to know how much overfull the oil has to be to go into limp mode?

 

oil level has nothing to do with limp mode. these trucks can run with no oil or over filled in oil. that tsb was referring to leaking injectors and one of the side effects is a overfilled crankcase. the oil level being high by itself causes no limp mode.

 

Thanks for clarifying that. I didnt see anything about the truck automatically reducing power but like I said I am a diesel novice.

Does anyone know how much oil these truck make as far as soot? Whats the allowance for oil level in say 5000 miles due to regen? Is that too vague a question?

 

i use mobil 1 5w40. just changed today put 15 quarts in 7,500 miles ago got 15 quarts out. i use a 15 quart pan fills all way to top. truck has 22500 miles and 775 hours. my old 6.0 had the same results with synthetics. the only time my 6.4 was over was when the dealer did my free oil change, 15 quarts in pan one on the ground. guess they put in 16 quarts, dumb ***'s.

 

I called Ford customer service and they told me there was nothing they could do for me. I just sent another oil sample to Blackstone and in the meantime I am going to call Ford again.

The first oil test revealed that my oil viscosity was 10w30 after 2500 miles. I really cant imagine this being any good for my engine.

This is the second time I tried to have it fixed. If I have it serviced again and they fail to fix it am I eligible for the lemon law or is it too late?
