Fuel in oil

[N. J. Jim]

If the level is that high and it wasn't overfilled to begin with, from my experience that would be over 13% fuel dilution. I had both 12% and 13% fuel dilution and both were just below the twist. Those tests were taken and sent out by the Ford dealer. There are copies of both tests posted somewhere in this monstrous thread. Ford also sent a technician to look at my truck after having me run 5000 miles on an oil change, which was about 3/8" over the twist. He took an oil sample back with him, but Ford will not share the test results of that one with me and told me that the excessive level is not harming the truck and that they will do no more warranty work related to that issue. They did however extend my powertrain warranty to 7yrs/100,000 miles.

So, that said, it seems my situation is an outlier and not the norm. I would bring it up with your dealer and have them look into it, at least it will be on record. If you take a lot of short trips, being cold and all does not help, and could be the cause. Some people have had the injectors replaced and/or the HPFP with success. I wouldn't freak out yet. Best of luck to you.

How about your air conditioner?

I tried to check all 200 pages but has anyone noticed any difference between those that do the auto start and those that don't. Those with crazy high levels are obviously the leaking high pressure pump or injector going nuts...... but curious if idling or trying to restart constantly would be more likely to cause a mild case of fuel in the oil.

My A/S/S has been disabled for a while now via forscan and on my recent sample, mine had 2.8 in the oil. Keep in mind my truck almost never idles, and it’s all highway miles. I don’t know if 2.8 is something to be worried about or not, but blackstone did say my oil was thinned out a bit because of the fuel. I change oil every 5K. I can definitely smell fuel when I open the oil cap when doing the oil change

I just checked my dipstick (only 1,000 miles since oil change) and it definitely reeks of fuel and oil is past the second hole by a lot. Definitely scary

I was just going to hit like but that seemed wrong to like a reply when someone has an issue. Thank you for the info.

I don't think anyone has had it worse than me? I have had my Auto S/S disabled since I bought it. I just use the night-lite option for that. For what it's worth, I live in the sticks and never take short drives. My commute to work each day is 50 miles round trip, 90% interstate.

I would love to be at 2.8%, hell anything under 7% and I would be thrilled.

A/C is working, it only took them 15 months to find the leak, at least it did up until it got cold out. I will know for sure come spring. Unfortunately, looks like my battery has finally went. It was at the dealer on Friday to check a " check brake system" warning, where I suddenly lost all power assist for the brakes, and also the battery has been constantly going into deep sleep. They told me the battery and charging system checked out good and it was dead the next morning (yesterday). This was my first time trying a new dealer.

Thanks for the info. It is cold here do I usually try to let it run a few minutes before I take off, but I work from home as of September and don't drive often. I ended up moving to a much more rural area in November, so when I do drive I'm going at least 18+ miles round trip. 55 and 75mph, respectively. I'll call the dealer on Tuesday and inquire if they have dealt with this issue before and see if they can take a look. I suppose its possible I slightly overfilled, but I dont think it would be possible by that much since I pretty much use an old measuring cup after the first container of oil, always a possibility though, since it was my first oil change on the ranger. Depending on how the dealer goes and/or their response I may reference those sheets you uploaded, if you don't mind. I would hope Ford wouldn't come back to me with the 3rd response they gave you. I am a little soured on Ford as of their wonderful vehicle launches and some vehicles myself and my Family has had issues with. (Focus DCT, to name one) That would probably push me over the edge. Dont' know what I would get though, now that I have a truck there is no way I could not have one as my vehicle and I get A plan with ford.

I ran a survey a while back to see what things might correlate with fuel dilution, and one of the things I asked about was auto start/stop use. It doesn't appear that ASS has any effect--either positive or negative--on fuel dilution.

Biggest factor appears to be length of daily commute, with short commutes being very prone to fuel dilution.

What is yours at, if I may ask? Not familiar with your story on your truck.

I've had 3 tests sent out by the dealer, and one sample taken by a tech from Ford who came to my dealership with the regional Field Service Engineer. The first one was 12% at 500 miles on an oil change. The second one was 13% with 2100 miles on the oil change. The 13% was after they replaced the HPFP and the injectors the first time. I posted a copy of each of those in this thread, they were done by US Oil using gas chromatography vs Blackstone's flash point method. After those 2 tests, Ford put a stop to sharing the results with me. They replaced the injectors a second time as well as the oil separator system and the high pressure fuel lines. Made no difference. They took a sample at 1100 miles and then had me run to 5000 miles for another sample taken by Ford, those are the tests they would not share. All in all my truck was at the dealer 17 times for this issue before they deemed it acceptable.

Basically, after an oil change, the oil will rise quickly to the twist in the first 500-1000 miles, then it will rise more slowly to about 3/8" above the twist where it will stay until the next oil change. At that point ~7.8 qts is what is drained out during oil changes and it reeks of gasoline. After the early comments from the Field Service Engineer, I thought I was going to get a new engine, but they decided, after the 5000 mile oil sample that the excessive fuel dilution was not causing harm to the engine and they would not do anything more. They did extend my Powertrain warranty to 7yrs/100,000 miles, so I believe I will get that new engine someday?

Damn bro that’s insane. Me personally, I would have filed lemon law on this one.

That's another crazy story...If I remember right his state's lemon law is focused on the first 12 months of ownership an his problems started close to the 12 month mark.

I also ordered the UPR crank case breather. I'm curious if that will help.

I have the CFM breather. I feel like it helps, but have no data to back it up. So far, my Blackstone reports have been good. Make sure you order some wrist sweatbands to put around the filter part

I don't think the UPR was available when I purchased the CFM (or I didn't come across it). For the CFM I think I ended up purchasing one for the Ecoboost 2.0. I looked at the UPR just now am curious when you get it on if you experience any oil getting past the screen after long trips. The CFM has a two stage baffle with a little ball to seal it off when excess pressure isn't venting, but some oil still gets by. Part I think is due to the angle of the hole and that it is so close to the motor, the tube part isn't very long
