I agree completely that lower is better, and 0% is ideal. However, what is the justification for 2% being the cutoff for max tolerable amount of fuel? I know that's the cutoff that Blackstone uses for whether to flag it, but that seems to be an arbitrary number that they use for all vehicles.
You may be right about 2% being an arbitrary number for Blackstone and truthfully that is the reason I used it.
Many thanks for these links!
No, it self adjusted, I run it hard, sport mode only, I assume the rings are just making a better seal, I’m @ 7000 miles now. It’s not my Daily Driver.
What's the latest on your truck?
After replacing the injectors a 2nd time, my oil level was creeping up every day and was 1/4in above the max hole after 300 miles (about a week). At that time I tried contacting Ford Customer service, but my rep has gone missing in action. For the past week and a half, I have left her several voicemails and a couple emails to call me back, so far no reply. In the meantime the level continues to rise and at 600 miles, the oil should be changed again as it is at the level that came back at 12% & 13% fuel dilution in past samples. I spoke to the dealership and they do not know what else to do, short of an engine replacement (their words). So I called Ford Customer care and spoke to a supervisor. I said I think my rep is on vacation, but they told me that was not the case and that they would have the rep call me soon? So I am waiting to hear from Ford as what to do next.
I'm getting ready to send an oil sample off, have a little over 400 miles on the oil change and it has risen to just at the top of the upper hole. I tried to tell my dealer were I thought my fuel dilution was, wouldn't take my word for it but said they would except test results. I've dealt with it long enough now I can perrty much tell how much fuel dilution I have. I will give him test results and recommend they change my injectors which has not been done yet. Hopefully in my case that fixes it or I will be in the same boat as you. Hope your case turns out the best for you, we shouldn't have to deal with this after spending the amount of money these trucks cost!!
That's just odd. It's not like these engines haven't been around awhile and are used in a lot of Ford's vehicles. You would think the bugs should be worked out by now.
It seems most people have had this issue resolved with injectors or HPFP replacement, or both. I have been dealing with this issue for the past 6 months without resolve, but I believe my truck is an outlier and not the norm. I certainly do not believe it is a widespread issue, but if your truck is affected, it definitely takes the fun out of ownership. I believe some fuel contamination is the nature of the beast with DI and I wouldn't get too worried just by the smell. Now if your oil level gets well above the max mark (top hole), then I would start to be concerned. For reference, if it is halfway from the max to the twist, I would estimate 6-10% dilution, closer to the twist I had 2 samples that came back 12% and 13%. I wish the dealer would have taken a sample when it was mid twist, I am sure that would have been close to 20%? If your oil level is near the max mark, either way, I wouldn't even worry, but I would continue to check it daily.
