Finally Hit 6000 Miles and Did the Second Oil Change

[ExpeditionAndy]

I had my oil changed this morning and I dropped an oil sample off at Blackstone Labs at 8:20 this morning.




I received my report at 5:07 PM and the only red flag is there is 6.3% fuel in the oil which is high. Blackstone recommends that while I have plenty of life in the oil at 5000 miles (I first changed oil at 1000 miles) because of the fuel, diluting the oil they recommend that I don't go any longer. In fact they are recommending that I have it checked out, so I'll be making that call tomorrow.

@Boose said there is supposed to be a drop off in the fuel dilution after about 10k miles or so according to other forums. Hopefully your dilution issue clears up with some miles. Get out and drive her!!

With the high dilution I agree change your oil often, honestly 5k is a better interval anyway

That has been my plan all along. Use full synthetic and change it every 5K.

I'll keep an eye on it, but I do have the 8 year 100K mile warranty so it will be Ford's problem if it doesn't clear up.

That’s cool you are so close to them!

Did Blackstone say what could be causing the problem?

No all they said is in the report above. I will call them tomorrow and ask question. When I first tested the oil at 1000 miles they said that gas in the oil was common in EcoBoost engines. I'm not sure if that's because of direct injection or what.

Very interesting! Thanks for sharing this, Andy! And please do keep us posted with what you find out.

Andy, I think a factor in your gasoline in the oil is due to the lack of driving you do. Just based on your mileage, it seems that you don't drive it a lot, and mostly on short trips. Thats an assumption. While the engine may reach a normal operating temperature, you're not driving it long enough to evaporate the fuel from the oil.

As a corollary, my commute is 2.5 miles one way, barely enough to warm up the engine. I find that in a week, my battery will die (happened 2-3 times already...same thing with my Explorer so I know its not the truck) because I don't drive enough to recharge the battery. I have to drive for a good distance 30-40 miles once a week or it dies. This also allows the engine to run hot enough, long enough, to burn off water and fuel collected in the oil.

Take another sample after a good hour or two of running and see what your analysis says.

VERY typical Andy.....your engine doesn't get the same "# of starts/oil at full temp for time" that most engines get so you'll see this for some time. It's NOT an issue so don't let anyone tell you that it is. It's just that you are injecting fuel under very high pressure, some is mixing with oil on a molecular level and is being scraped off the piston walls and mixed back into the rest of the oil....it will lessen with time and of course real miles buddy!


FWIW- I take my mobil 1 full syn 5-30/purfilter to the local guy, every 5K....last time my oil life showed 61% remaining!!

I’m curious how you think Ford would fix this if for some reason it is an issue? You walk into ford and tell them you got fuel dilution they’re gonna tell you it’s normal and send you on your way.

Bobbmx said it perfectly, it’s the low mileage and lack of long trips to evaporate any condensation or fuel in the oil. It’s like the peanut butter people get under the oil fill tube in the winter if they only take short trips. This is caused because condensation isn’t evaporated out from long run cycles and stays under that cap. I’d say andy’s Issue has to do with that. He had very low mileage for owning the truck a year. So yes your are most likely correct, there is really nothing ford can prescribe other than to wear it in more, just as they couldn’t do anything about the peanut butter in the fill tubes.

Andy I think this is directed at you

I'd look into adding a catch can ASAP. And I'd probably go with the largest size available with dual valves.

Agreed though, Ford dealer isn't going to perform any action based on Blackstone findings other than change your oil.

Is your truck garaged or does it sit outside in cold Ft Wayne?

I think you are right Bob. I came to that conclusion myself. The issue is I don't have anywhere that I have to go on a regular basis. Not like when I was working and driving 30 miles to work (one way).

That’s it Andy! It’s time to get an Uber job! LOL

Ha ha! LOL. I really don't like driving any more than I have to. When I was younger, I wanted to drive everywhere. Now I just don't want to go anywhere.

 

[deweysmith]

Yeah, I was under the impression fuel dilution was normal for at least the first 7500 miles or so.

Blackstone also says that if you don’t drive it for a good bit before taking the sample that it will show high on the fuel dilution for the reasons stated above.

It's always a good idea to run any vehicle up to operating temps. Short stop and go is not good for any motor, new, or old. Fuel is always on the rich side when cold, due to cold start conditions. Not running long enough, will dump rich mixture into the crankcase area. Not to mention condensation, that doesn't get fully burned off. Bottom line get out their and run it up to temp, and clear everything out!

I tried really hard to find the link on the F150 Forum regarding the 10k mark with fuel dilution. Honestly I found a lot of information about 6% being the norm for these motors. The DFI pressure is typically mentioned as the cause. I'll keep looking and post it as soon as I find it!
