I'm really struck by how quick these engines sheer down oil viscosity, even in engines that don't have the fuel in oil problem. I was planning on 5k oil change intervals but may have to lower that. There is no way I would go by the oil change monitor.
Yup I dont trust that oil life monitor AT ALL. And to answer the other question I put maybe 4,000 miles or so on this oil after hpfp replacement. This next interval will really let me know if replacing that hpfp did the trick or not but so far it is looking pretty good.

Got my latest sample back after having my HPFP replaced under warranty and it seems to have remedied my fuel dilution problem! They only found trace amounts this go around and recommended i try a 6,000 mile interval this go round. So fingers crossed hopefully im on the up and up now!
Was it your dealer's idea to replace the HPFP? My dealer claims my 2.5-3.0 fuel dilution is not a problem and is due to short trips so there were no recommended actions on their end!!!!

Is there a reason why there isnt a tsb or some kind of lawsuit? I see this happening with way too many people, and zero mention on carcomplaints.com. Which is what i used to see if any known major issues were known when purchasing the truck.

Now the PCV system might be another issue. With a proper amount of fresh air turnover in the crankcase, the fuel vapor should be adequately removed. Could a restriction or improper valve switching be the cause ?
Hmmm....if your having this problem, why not try installing a catch can and see if that fixes the issue? Mind as well, right? I've had mine on for about 20K now and absolutely no fuel issues in the oil....<0.5% last Blackstone. (In all fairness, never had the problem)
Engine Build Date: 10/28/2019...Purchased 02/20/2020.
Just have to make sure and keep it emptied if it is a small can. Would recommend a large can...at least 7.5 oz.
Also, the UPR cans with the continuous vacuum are probably your best bet. I have a Mishimoto catch can and would definitely recommend there products, just get the XL can and the drain kit.....
Also, remember due to the chemistry of fuel when it is cold and wet you will need to empty that small 3.5 oz can every fill up. ;)
IMHO as always.....

I'm curious, since Ford obviously has not acknowledged this issue, has anyone with "fuel in the oil" or "an increase in oil volume between oil changes" actually had a problem that needed to be repaired or diagnosed? Has anyone had a noticeable decrease in power or some kind of sign the engine is not doing well? Just curious....this thread has been beat to death with stuff and I'm interested in long term data with this. I know a number of folks in here have been dealing with this issue for thousands of miles.....so how are your trucks running?

I can only speak for myself. I am having issues in the morning with the truck slamming me in the back seat when it goes in gear. Also lately when I give it the gas going up a small incline, I have to push the pedal almost to the floor to get it to go.

Don’t know if it is related or not.

I now have a different dealer working on my issue since I moved out of state. Last time I had the oil changed with 5k on it they said they didn’t find gas in oil when they changed it nor was it overfilled. I asked for a sample to be pulled and they said they would be testing it themselves.

You spend 30 to 40 thousand and have to come up with a fix on your own. Something is wrong with that picture. If that's what buying a new vehicle has come to better off fixing up an old one! NEW TECHNOLOGY I GUESS!!!

Well, the thought had crossed my mind, but I don't want to do anything that could have any possibility, whatsoever, of Ford claiming it as a cause and denying warranty. Besides, it is Fords responsibility to honor their warranty.

Man I completely understand what you are saying. I feel very blessed not to have this issue! Just so you understand where I’m at on this...I’ll be honest, I had no idea these 2.3 L motors were the high performance machines that they really are until I bought the darn thing. Now I’m at that age where you get a little squirrely anyway at 57...you’ve got one foot still in your young side and 1.5 in the old bugger side. Saying that, ole papaw here never had a hot rod car or bike growing up so this is my first vehicle I can tinker with to make her go fast, then take her out and have some fun. I know this issue is very serious to some folks! I say this with ALL do respect but unless there is a mechanical problem from this, some folks may be overthinking this issue. That is why I asked about real problems associated with this fuel in the oil or expanding volume of oil issue.
Also, I am wondering if these motors were meant for regular driving? Seriously I wonder if you don’t drive it hard does it cause issues? Just my scientist hypothesis side showing up. Sounds like a study to me?
Who has a spreadsheet going on this for some real time data collection and analysis?

Totally understand! Just know that catching the fuel/oil vapor from going back into your motor will not void any warranty. I catch at least .5 to 2 oz per fill up...at least! Much more when it’s cold. If I would have seen the pictures posted of catch can contents earlier, I would have put one on immediately. (Installed mine at 20K) Heck, I didn’t check mine for almost the first month and was shocked to find my catch can full. Now look, I’m NOT saying this will fix anything or is the cause of anything. I just know I do not want the crap I catch in the can going back in my motor! Can’t be good in the long haul....IMHO as always
I know some folks think I’m a nut head with some of the stuff I post but I tell you what...my truck runs better than it did the day I bought it on 02/20/20! I have had no problems with engine or transmission and I’m at 39,633.4, and I run the heck out of her daily. I’m that AH in the Ranger on the street. A chunk of the local college kids know my truck well and I actually have a hard time getting my target audience to play...lol (That would be late model Subaru STI’s and Evo’s) I don’t know what it is but when I hisssss at them on a drive by, they tend to slow down...no kidding, it’s frustrating for an old bugger like me?
Oh well, I try...lol

So I am at the dealership right now getting an oil change. The service manager just came up to me and said that the tech working on my truck noticed my oil smelled of fuel. They are draining the oil and marking the dipstick. They are also replacing the saggy leather driver seat bottom. He told me that they will check the oil when I bring it back for the seat repair but want me to monitor the oil level over the next 5000 miles.

My engine was built in June 2020. I have 8000 miles on it. First oil change was done at 3000 miles.

I check my oil every couple weeks and did notice a slight smell of fuel and my fuel level was always close to the top of the hash mark but never over it.

Maybe Ford is starting to recognize something is going on?

You didn't say anything to the service writer beforehand? That's oddly proactive of your dealer. Where do you find one of those?
