I don't think the oil in fuel problem is a single batch of bad parts or manufacturing errors. There are numerous different reasons and the wide variation of manufacturing dates is not surprising. Some of the causes forum members have experienced include:From ones that have replied the build dates the problem is all over the place. Figure that out.
Everyone thus far has been a 2019.From ones that have replied the build dates the problem is all over the place. Figure that out.
If the 3/21/19 in the list is mine I have had no issues. Although they still are 2019s.Everyone thus far has been a 2019.
Mine is a 2020 built in early March. It had 3.8% fuel dilution according to Blackstone Laboratories. But that was with only about 4300 miles on the engine. I have recently put about 800 highway miles on it and the level on the dipstick has been completely stable. On my Ranger it appears the oil level rises when I have numerous short driving trips and while towing.so no 2020?
Wonder if you'd see improvement to oil level if you remote start the vehicle (with either fob or the FordPass app) 10 minutes before you drive each day on a short drive? Would be an interesting experiment as well. Not sure what it would imply but something about the cooler being too big/strong compared to Mustang 2.3L. Are there aftermarket coolers that could fix this issue for anyone stuck with it?Mine is a 2020 built in early March. It had 3.8% fuel dilution according to Blackstone Laboratories.

I will be monitoring it closely on my long towing trips next summer but so far my problem seems to be getting better like @Doc experienced with his Ranger.
I don't use remote start but I think it may make the oil dilution problem worse. It is my understanding that a cold GDI engine tends to have more gasoline condense on the cylinder walls that can end up in the crankcase oil. Remote start and the subsequent idle time results in a longer warm up period as opposed to driving at moderate speed immediately after start up.Wonder if you'd see improvement to oil level if you remote start the vehicle (with either fob or the FordPass app) 10 minutes before you drive each day on a short drive?

Good to know. So I wonder is there a such thing as an oil heater add-on that could activate early on?I don't use remote start but I think it may make the oil dilution problem worse.

The main problem with short trips, as I understand it, is that the oil never reaches the required temperature to evacuate the accumulated gas in the crankcase. On my Ranger I have observed the oil level on the dipstick coming back down after a long non-towing highway trip.
Interesting question. I think some styles of engine heaters (for northern winter weather) do heat the crankcase oil. My Ranger (he is a Minnesotan) came with a factory block heater. The owners manual says this about it:Good to know. So I wonder is there a such thing as an oil heater add-on that could activate early on?
The heater acts as a starting aid by warming the engine coolant. This allows the climate control system to respond quickly. The equipment includes a heater element, installed in the engine block and a wire harness.
Using that heater yours came with may be an interesting test you could perform even before summer, and ultimately put this mystery to bed for everyoneInteresting question.
