What has the dealer done to correct fuel in oil for you

[Rickfar]

I have an appointment on the 31st of this month to take my 2019 ranger in with only 14,500 miles for fuel in the oil looking to see if anyone here has had the same issue in the dealer has corrected it and what did they do to correct it just trying to get some info here because according to oil samples, I’m at 2.5% dilution over the last four test I don’t know what the dealer does to diagnose it, but I’m just curious if there’s anything that can actually fix this Blackstone has said that it is lower in my viscosity and the only thing Ford said was change your oil frequently. The oil has been changed in my vehicle at least five times and 14,000 miles. I have never owned a vehicle where the oil level went up. I’ve owned a few back in the day where it went down quite regularly. I remember an old Vega I had that would drink oil regularly.. just checking if there has been any success in getting this issue corrected

I'm not sure what issue caused fuel in the oil for members on this forum but I didn't have it happen to my 2019. I did tge Blackstone analysis a while back out if curiosity and it wasn't highlighted. At now around 60K miles the oil level stays pretty consistent between oil changes.

I really wanted to comment on your thread as a former Vega owner as well. I had the station wagon, blacked out the rear windows as a mini shaggin wagon. Drove that thing nearly to death and yeah - it needed a regular feeding of oil.

When my truck had 4k miles on it, I took it in for making its own oil.

The dealer found that the HPFP was leaking into the crankcase.

Replacing the pump solved my issue and that has been 5 years and 33K miles ago.

If it's not a fuel pump or injector issue then it might be as simple as driving it more. Its a 2019 with 14k but it's also 6 years old. So at minimum if you changed it yearly, as you should due to time, then thats 5 to 6 oil changes.

The oil needs to reach operating temp and be driven long enough to burn off the fuel. I have a 2005 gto that stays parked. If i start it and let it just idle the oil has a strong fuel smell. Take it out for a nice ride and it smells normal.

I am well aware of the concept of driving the vehicle, reaching operating temperature and burning the fuel off but when it gets to the point of there’s 2.5% or 3% fuel dilution it just won’t burn off. I have taken the truck on 200 mile trips and there has been no change.

Rick, I think the point that was made is it appears you take a lot of shorter trips. Engines are not a fan of that, especially direct injection. They are more prone to fuel contamination. So you drive 2-2500 miles a year. Is this a daily driver or a weekend toy? Context helps so we can better help you.

Did Blackstone point to any specific damage that level is causing or is going to cause? Or, did they just say it’s diluting your oil? Is there a figure they consider to be critical?

My experience with a 2023: I put a catch can on it right after purchase and put in top tier synthetic for the first oil change. I had to empty mostly gasoline out of the catch can ever 400 - 500 miles (almost full). I was getting about 19MPG. Once the truck covered about 15K miles, There is very little gasoline in the catch can at 1000 mile checks. MPG has increased to 24MPG. My assessment that it takes awhile for the rings to fully seat and seal and until they do there is a lot of blow by going down into the crankcase.

Well, I am no rocket scientist but I would assume that if your oil is thinning out too, it’s not the proper viscosity that the engine was designed for that it could cause a problem

their consensus is that it should be under 2% I was running 2.5%. This is not the first oil sample. I have said I have sent a total of four samples. Interesting thing is the second sample I sent to them. There was just a trace of fuel, but then it climbed for the next two they pointed out that the viscosity of my oil has changed, which makes sense.

When I bought the truck, I was company vehicle so it was not driven as much. I retired and I drive the vehicle, which is my daily driver. I understand the concept of not letting the car warm up and having the fuel not being burnt off, but I have driven that vehicle and gotten it up to temperature so many times and it does not change the level of the fuel. Is it possible I’m getting blowed by is it possible that an injector is dumping fuel on top of the pistons leaking, I don’t know. I just want Ford to look and see if they really is a problem.

I don’t think you’ll get anywhere with Ford on their dime but I’m sure the dealer would gladly take your money to try and diagnose the problem. Dennis (above) mentioned a good starting place (HPFP).

I don’t agree with Ford that you should simply change the oil more often but if the dealer can’t figure it out, you might want to buy an oil extraction pump and remove and refill a quart or two of oil every now and them. It doesn’t solve the problem but it does lower the percentage of fuel.

I do have an ESP extended warranty that does not expire until December 2027 but once again that’s not the point. I bought the extended warranty just for this scenario as I have never bought an extended warranty with any new car that I have bought and I have had quite a few.

I looked at that pump for $37. That seems like a pretty good deal. I think I’m going to order one not that it’s going to solve the problem. I was wondering if anyone has had experience with that as the longevity of it.

What is the time intervals between your oil changes?

 

[Rickfar]

The first oil sample I sent in at 1700 miles. The oil had 500 miles on it that was done on 11-27-2020 and that had 3.8% fuel. The next oil sample I sent in. I had 2237 miles that was done on January 9 of 21 and at that time I had a trace of fuel the next oil sample was sent in at 5543 miles on 1-10-2024 at that point I had 1.5 fuel dilution. The next oil sample was sent in on 1-2025 with 7700 miles and at that point I had 2.0 fuel dilution the next oil sample was sent in at 12,263 miles at 7-31-25 and at that point I had 2.5 fuel dilution according to them it says fuel is back in this time. It made it up to 2.5% it’s possible this longer run just allowed more time for fuel to accumulate, but that’s still not a good trend . monitor for a rising oil level on the dipstick fuel is also likely responsible for thinning the viscosity out of spec for 5W-30. Most metals only shifted by one PPM and the increase in iron isn’t surprising considering that metal tends to track with oil use . now to add to this the oil was changed at least two or three times not counting these . these oil sample was never sent into Blackstone.
