Fuel in oil

[Stevedbvik1]

If you are traveling from Michigan to Florida, I predict your oil level it is going to go back down with your long drive where the oil gets fully up to temperature for numerous hours.

I thought about that too. It will be interesting to see. My gut is that it stays where it is and doesn’t increase. I think what fuel that is in there now is fully diluted with the oil and won’t evaporate.

Being I have been through this once. At what point on the stick should I start to worry about it. I try to drive it a little harder in the winter to see if it will help. At the oil change I was about a 1/8" above the hash mark and 1500 miles later I am above the overfull hole and closer to the twist. I really didn't want to go back to the dealership but not sure what to really do. I figured at least they could document the issue and hopefully check the HPFP & injectors for leaks.

When I change the oil and filter I only put 6qts back in. Never had an issue and the level stays reasonably low. My 2019 and 2021 smell exactly the same but I stopped worrying about it and it hasn't blown up.

Mine does not go back down after driving even very long road trips.

Well I have been out of the conversation for a while. Traded my 2019 FX4(had oil rise issue)for a 2022 Tremor. Was good the 1st 5000 miles. Now it’s been 1500 mile since the oil change and it is between the overfull hole and the twist. Talk with dealership(same one that was dealing with my 19)tonight and he told me to call him back in a few days for an appointment. Here we go again. But question , doesn’t the Bronco have the same motor? Do they have the issue too?

My family has a 2.3 Mustang and a Ranger, No oil issues.
What are we doing different?
I guess the question really is... Are there driver induced causes of this problem?

As a fleet Mechanic, I found that some people could completely destroy an anvil with a rubber mallet.

I think short trip driving on any car will show some fuel dilution, even Honda 4 cylinders I’ve seen raise the oil level and then drop once a long trip is done.

I do regular 1,000 mile round trips (when going to jobsites for work) so my shortest trips are like 30 miles round trip, lol…

I believe the problem is hit or miss. I think this one is a bad injector. I didn’t see a rise til I had it set for 4 days without driving it.

Am I the only one that has the opposite? Go on a 1,000 mile round trip and it actually burns off some oil when towing. So far after 6k I’ve had to put 1/2 quart in…

First time I have heard of that. Cold weather short trips and towing is when mine makes oil.

Not really sure. I don’t drive aggressive but not a grandpa with it either. I drive it the same as my 2014 escape with 2L eco boost and in 130000 miles have never had that oil level creep one bit. So not sure why the 2.3 does it. My 2019 had the same issue and I admit I dove that kind of easy that could have contributed to it, but the 22 I drive a lot harder and seems to have the same issue. I do love the sound of the MBRP duals I have on it. ?

Towing a light <3500lb load around town or thru the mountains, across multiple states?

My towing is the latter, I’m thinking short trip towing would still dilute the fuel with oil.

How do we know the engineers didn’t design the 2.3 EcoBoost with this in kind? Maybe it’s supposed to dilute the oil and this is normal.

Because the manual (and dipstick markings) and engineers who look at this at dealerships say it's not expected. When the problem is fixed (eg leaking injector) this doesn't occur anymore.
If they designed it for this, they certainly went out of their way to obscure this info from all angles -- and the existing fixes that stabilize the level for some people, would then be treated like new issues that need fixing since the oil is NOT rising

One more piece to the puzzle - the dealer replace the purge valve but I noticed (due to it being cold outside) my truck took a long time to warm up. Like 3 miles to get heat. That's a stuck thermostat and maybe the real cause of dilution as it's not getting hot enough. I wouldn't have noticed it in warm weather so that makes sense. Another appt next Friday to sort that out.

Are thermostats still mechanical or is there an electrical component to these now? Anyone else have this issue?

It appears to have happened to me yesterday. Took an unusually long time to throw heat. Temp gauge stayed below 1/4 then finally swung over to its normal just-below-1/2 position. No codes, but engine did hitch a couple times. I’m uneducated but feels like an open thermostat.
Appointment booked.

I see the same... short trips less than 60 miles over time raises my oil level. I just checked it before travelling on a long trip. 1500 miles on this oil, driving around town. Oil up 1/2" on dipstick. (I use the second trip odometer to keep track on miles on the oil.)

Drove 600 miles round trip and oil is now 1/32" above full mark. Truck parked in exactly same location and sat over night before checking the level both times.

BTW, my UPR Catch can had accumulated 2.5" of fluid in it after the 600 mile trip. I emptied it the same time I checked the oil. Before the trip and after.

Don't freak out just yet.....I would check to make sure you have installed the can correctly but you may be just seeing normal ops on the can. Since you are in Texas and in warm weather you will catch a very golden fuel/oil mixture in the can. When it gets below freezing and wet it changes to a milky, clay looking concoction with some clay like gunk in the mix. When I haven't emptied my can it smells like fuel in the garage but I can assure you there is nothing wrong with my Ranger.

Running a catch can takes getting used too....It tripped me out at first but I've had my Mishimoto can installed for like 2.5 years and no issues. Just have to make sure you empty it....

BTW....2 things will affect what you catch in your can.....fuel octane you are burning and temperature....
High octane (91-93) and warm weather will produce a very toasted, golden colored fluid mixture. Also, high octane use should keep warm weather amounts caught in the can to just a few ounces per month. Winter catches in the cold wet weather are excessive. I have to empty my can each time I fill-up. I run 91 octane and my Ranger is tuned.....that may make a difference also in what I catch.
