Hey, OP here. I assume most of you are familiar with my original story with the rapidly rising crankcase levels. Since having my injectors replaced 20,000 miles ago the problem has never returned at that same level. However, during the very cold weather we had not long ago I did notice the oil level rising just slightly, as many of you have noted in your own trucks. It didn't concern me much, but it got me thinking about using an injector cleaner, which the tech who fixed my problem recommended I do with some regularity. So I bought some Lucas upper cylinder lubricant and injector cleaner, and added it to my tank. This coincided with warmer weather, so you can draw your own conclusions with that. But my oil level went back down and fuel economy increased substantially. I got 28 mpg mostly cruising at 73 mph over a 400 mile trip, confirmed at the pump. My truck has 4wd with the FX4 package too. Thought I would share that with you guys experiencing more "mild" cases of rising oil level.

Wade, are you still using 5W40 oil? Any additional thoughts on that?

I never used 5w40, only ever used 5w30 (maybe I made a typo in a previous post) but I did switch to Rotella gas truck 5w30 and only occasionally have used anything else since.

I used 5_40 on the last oil change, I now have 2300 miles on it. Seem to be making out better with fuel dilution, don't know if is is just a coincidence . I have had the level go up to the twist in the past, since switching my highest level has been the top hole. And driving on a longer trip will bring it down . Have been to the top hole and with a couple 100 mile trips brought it down to about an eighth inch over the hash mark. Never experienced being able to bring it down before no matter what I did short of just draining some out. Now I'm not claiming anything just stating my experience. I do keep a close eye on it and check it in the morning after it sits all night! I forgot to mention I also used AmsOil gasoline P. I. performance improver, a fuel system cleaner with that oil change. As Wade stated that also could have helped my situation!

Thanks, Jim. I remembered wrong who was trying 5w40. It has to help the viscosity level with our moderate oil dilution.

Yeah, from my experience during the last 8 oil changes in the past 11,000 miles, it moves fairly quickly up to the top hole. My guess is, that the shape of the engine cavity results in it rising quickly at first and then a bit slower when it gets up to the twist area. The field service engineer and a tech from Ford were at my dealership to run some tests on my truck and they took an oil sample back with them. This was 2-1/2 weeks ago, and within 300 miles I was about an 1/8in above the max hole. Another 200 miles after that, and I am now just below the twist. From my experience, it starts to move much slower when it gets into the twist area and levels off about 3/8in above the twist. I don't know what happens at that point, but it doesn't seem to rise further? Just above the twist is about 1.6qts of gas as measured during one of the oil changes. I had a voicemail from Ford Customer Service this morning and they will be calling me back on Monday. I am curious as to what the next steps will be. I have also not seen the results from the last 2 oil samples, but the first 3 indicated double digit fuel dilution. For reference, all 5 oil samples have been taken by Ford and sent out for testing. This last one has way more miles on it, as the Field Service Engineer wanted to see how bad the wear metals got after 5000 miles on the oil. I will be sure to update when I hear back from Ford.

Curious if Ford ever called you back and if you got the results of your samples yet?

Nothing yet, I was originally told I would hear something in 1-2 weeks, but it is now moving on 4 weeks. Dealership has told me they cant do anything until they hear back from Ford, so still waiting.

Hello all. Got my truck back today after two months at the dealership. Here is what they did. Hopefully this solves it.

Thanks

Yep it’s the workshop manual procedure to change the injectors.

I’ll be putting some miles on the truck the next few weeks. So I’ll keep everyone updated.

Hopefully your dealer cracked the code an fixed your problem an can share it with the rest of the ford service network.

Well the honeymoon is over with my new truck. Seems I am plagued with the fuel in oil disease. Just over 5k miles on the truck and oil level is rising and now reeks of fuel. My Ranger smile just turned upside down....

I hear ya bro. Just changed my oil over the weekend and the fumes had me yelling at my son to get away from the truck with the lit cigarette ? I got a sample out to Blackstone for analysis so should know more shortly. At this point I would be speculating and that’s not how I want to deal with this if it is a problem. Look at it this way, everyone on here with similar problems have not blown up their engines yet so that’s a positive point, right!

Didn't someone mention in one of these threads that the fuel system was priming itself periodically with no input from the driver? That they could hear it doing that outside the truck?

If that was true, it would explain a lot if the injectors were leaking.
