4%fuel in my oil

[Qball1976]

Well I have an 08 F250 with the 6.4, I sent my oil off to be analysed and low and behold, it came back that there was a fuel contamination of 4% in my oil? Any Ideas as to what would cause this? I know 4% dosent sound like much, but it is about a quart of fuel in my oil. if you want to see thr results of the analisys, HORIZON FLUID ANALYSIS REPORT, is the address. I took the truck into the Dealership, and it will be a week before I hear anything, just want to be prepared for what they might tell me. Does anyone else here run oil analisys?

Just let me know what you think,

Thanks in advance for the help,

Ok, so after 11 days of my truck being in the shop, and having to bum rides and ask to borrow vehicles, I ge a call from Arrow Ford in Abilene, Texas. The guy on the mechanic on the other end of the phone says "Mr. Galinak there is nothing wrong with your truck, after 7000 miles it is normal to have about a quart of Diesel Fuel in your oil"

To which I replied "do you drive a diesel truck"

He said yes, I said ok, I will bring a quart of diesel fuel with me and we will pour it into your oil fill port. He said there is no way he would let me do that. I asked why should it be normal for my truck to have a quart of fuel in the oil he said that the CJ-4 Lubricants designed for the 2007 and newer Diesels were designed to hold fuel.

I said put that in writing, as I am an amsoil dealer, and nowhere in our DEO specs does it even mention increased fuel handelling ability. He said that that's what the CJ-4 spec was made for.
I told him to get me a service manual, or some official manual that says a quart of fuel in the oil is normal. I got provided an email from Ford Motor Company's Tech hotline that says:
"There is no supporting documentation about the fuel in the oil. Also Ford Motor Company does not recognize oil analysis. The reason for the fuel dilution is due to the regen process. When the vehicle is in regen the injectors fire on the exhaust stroke to get fuel into the exhaust system so the DPF can be cleaned."

This still isn't an explination why it is in the oil, it tells me that the fuel should be in the exhaust system not the oil system.

I told the mechanic I will be bring it back when my next oil analysis is complete wth the same problem, he said I will give you the same information.

I am an aircraft mechanic, not some idiot off the street that can't tell a diesel from gas engine. In my book NO amount of fuel in the oil is acceptable. I let the service manager know this and he said you will just have to accept this as normal. I told him I am glad you do not work on aircraft. and left as I was mad.

I called my lawyer he said this can be lemon law'd, that is the only avenue I have left, I will let you all know how it goes, and keep you posted on the results of the succeeding oil analysis. If you have any questions please ask I will be happy to answer.

And before you ask it is not ARROW Ford's policy to give anyone a loaner vehicle while it is in the shop, even for warranty work.


Later all and happy reading,

Good luck bud, I hope you're efforts get results. The dpf reason sounds like bs to me.

Hmm, If I can dig up all my info from Ford that says its normal I will. I think its in my tool box though.

I can't find any, other than the words of the "trained mechanic's" at the Ford dealer, so good luck with your tool box search......LMAO

i think someone got mixed up on where you put diesel in it and put it in the oil fill-lol jkjk

had to put some humor in this thread

i acidentilly did something simalar to that- put a gallon or two of hydrolic fluid in the fuel of a 621b cat scraper. didnt relize untill the guy telling me below when it was full said "it aint moveing, are you positive your not pouring it into the fuel tank?"

that makes no sence tho, a quart of fuel in your oil???
i know i defantly wouldnt want a quart of fuel in my oil, it might get a little too thin

As one Av-Mech to another....Oil dilution has gone the way of the radials. It had some nasty side effects like increased wear and tear, and if too much fuel is in there, seals and gaskets start blowing out. I looked through several tech manuals (none for the 6.4 though) and none of them had allowances for fuel in the oil. Sounds a bit counterproductive to have something that thins your oil.

[Qball1976]

yeah having fuel which would act as a solvent would strip the protective coat of oil off all surfaces that require lubrication, which would increase the instances of direct metal to metal contact, in turn that leads to increased wear......I could go on, but I think I will skip to the expensive part.......leading to the complete destruction of the engine


so I vote no on fuel in the oil

My dealer told me the same thing.... This is total BS. WTF They couldn't give me a straight answer or show me documentation that this is normal. They said it is normal due to regen. So why didn't my oil rise for the 1st 4k and by 5k the it was almost 1/4" over the bulb. I have a sample to send off to Blackstone but am kind of bummed that you said Ford does not recognize oil analysis. Anyway, I was so pissed that I Spartanized my truck and I will see if regen has anything to do with the oil level rising now that I have the dpf deleted. I don't know if it is helping my oil making problems but it sure runs great now.

I have a similar problem. Sent off sample to Blackstone. Came back with 8% contamintion. Dealer said there is nothing wrong.
