This was posted over in the SHOForum today.  Don't know if anyone has heard of this already, so I have "pirated" it over here.

There may be a conflict of interest, as you will see, judge for yourself.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

It is a pretty common problem in any DI motor, gas or diesel.  I change my diesel truck every 3k and I let the EB go to 4500-5k miles.  No way will I go to the 7500 or 10k like I think the 2011+ say...

Just change your oil/filter consistently and you will be fine.  A tuner will probably help with the fuel dilution amazingly enough... :bangin:

Sadly it is the wife's car, so I can't go too crazy on it...just a simple tune for now.

A shorter OCI seems to be the cautious consensus solution so far.  I wonder if the manufacturer's "time to change the oil" monitor takes this into account when calculating oil life, and does that calculation try to maximize the health of the motor as well?

Why is it more common in a DI engine vs port injection?  Realize FRP is between 400 & 2,200, but actual amount of fuel in chamber is same or less.

2010 EB engines use 5w-20 vs all later EB using 5w-30.  Was told by dealer and tuner(s) to use what factory recommends.  So, wouldn't 5w-20 be even more cause for concern?  I have never smelled gas in my oil, which I change myself.

Got slammed on SHO Forum by one guy for questioning all this. I certainly don't mind being wrong, I just want to know WHY and what we should do to keep this to a minimum.

I am no expert by any means, but it has something to do with (contrary to popular belief) the fact that DI motors always run a richer fuel map.  It has something to do with keeping NOx levels down.

Oil changes and trying to cut down on the short trips will keep it to a minimum...Either way, I doubt you will get dilution levels so high that they cause major problems.  If so, then there are bigger issues to worry about.

Sorry for bumping a old thread.

I am new to these Ecoboost, I heard about the fuel dilution, so I sent in a sample.
here are my results...

looks like shorter OCI will be my path too( pending the results of my next sample)

What oil are you currently running?  Try switching to full synthetic (Royal Purple, Mobil 1, etc.) for lower volatility, less PCV emissions, and less "feedback" into the crankcase.

Agree with this wholeheartedly!....
Currently Amsoil syn is my go-to oil as it beats them all in industry tests and in volatility it eclipses them....

That sample was in it when I got it, so it was either Motorcraft or Valvoline ( What ever the Steelership was using)
It has AMSOIL ASL ( 5/30 signature series ) in it now. I will pull another sample about 1/2 way through my OCI

I am a Jobber with AMSOIL   so no need to sell me on the value of good  Synthetic oil :)

Alrighty then :D  Yeah, I fuhgot about the "work car".  If you keep getting too much gas in the oil even after the Amsoil, I'd be surprised, unless of course one or more injectors suddenly let go.

I will pull another sample  and go from there.

Maybe if I show that report to my wife  she will let me put a tune on it ;)

Yeah, might as well use the gas to go fast-er!
