Fuel in oil

[geophb]

For anyone curious (mainly I was):

6QT fill.
4% dilution = 1 cup of gas in oil
14.3% dilution = 1 qt of gas in oil

Got my 2nd oil test done after another 1,000mi. While it's better it's still not where it should be. I made a conscience effort to disable the auto/start every time I was in the truck (just guessing that the priming of the fuel pump repeatedly was contributing to the issue). I will wait until I got 2,000mi on the oil for the next change which will put me at 5,000mi on the truck. I had 2.8% fuel contamination last time and 2.5% this time which gives me hope the issue will work itself out.

After reading this entire thread I'll admit I was a little paranoid about fuel in the oil. It seems I may have dodged this bullet. One thousand miles on this oil change. I've been paying close attention to the oil level. It has not changed that I can see and the oil smells like... well, oil.

I will be sending a sample in for a UOA at the next oil change.

I am new to the forum and have not yet made any entries,until now. I have read over a good deal of this forum and all 52 pages of this thread as well as to numerous other threads related to the making of oil in the Rangers crankcase. I have yet to hear about a definite cause other that perhaps a few replaced HPFP or injectors. This from the threads I have read does not appear to be a definitive fix to the problem. I seriously doubt that the few individuals here are the only ones experiencing this issue. There are exponentially more out there that will buy their new truck and assume its fine till there next oil change at 10,000 miles. And likely even then not be made aware if the fuel issue until a serious problem occurs. I in fact owned my previous truck 19 years and likely only checked the oil in it maybe 20 or 30 times. Never once had any issue with the oil. Not a drop dripped from it and never any issue with fuel dilution. And she went all over the country and was rode hard at MOAB and many other locations. I was only prompted to check after reading some of these threads here on the forum. And yes there is serious fuel in my engine and the dipstick is showing up well above max after sitting level for hours. The truck is my daily driver for now as my 19y old Tundra is needing a little service. Going to send a sample off to Blackstone next week when I get the kit in and planning on taking her in to the dealer next week. She's at 1,600 miles now and not sure how long the level has been this high. Really smells strongly of fuel but the issue really is the level its at. She does mostly short drives of only 7-10 miles at a time so really really getting warmed up to speed.
Looking at these 52 pages it appears the only certain fix is a different truck. A replacement HPFP and injectors might fix the problem for a little while. But who here that has had this problem is willing to drive their truck 10,000 miles without checking the oil every few hundred miles for fuel.
A quart of gas in the engine block is not something that gives the owner the warm and fuzzies. I really do like this truck but would I have been better off had I gotten the TACO. Certainly would have had a better opportunity to blow loads on additional accessories. Something I am glad I have yet to do on this Ranger. Although I do have a long list of mods ready for the right opportunity and vehicle. This thread is now 1 years old and I don't see the solution anywhere on these pages. Hoping that changes in the next few months or will certainly have to consider this fuel thing a BIG FAT LEMON.?

I am also new to this forum and this is my first post. Your concern is perfectly reasonable and understandable to me. Funny thing is you mentioned about the Tacoma and I just traded in my 2016 Tacoma last week for a 2020 XLT (build date is 8-10-2020). As of last night, my truck had only 177 miles on the odometer and the oil dipstick smelled like gasoline. Maybe it is normal for a DI engine, but time will tell.

Smell will be normal, just look for climbing dipstick. That's not normal.

I'm the OP. I felt a lot of regret when I first had this problem like you are, especially because my dealer refused to acknowledge it as a problem. 10,000 miles since getting new injectors I've yet to have a problem since. I'm super happy with the truck since then. I hope you can get it fixed! For what it's worth, and I might be wrong, but I don't think anyone in this forum has gotten a permanent fix from replacing the hpfp. Only injectors have resulted in permanent fixes, though I might be missing somebody, and there is one guy for whom that didn't even work. Good luck getting it fixed and I hope you enjoy your truck like I do now!

Somejoe, FYI the newer Tacos have bad fuel pumps also and they wont be available for months.

I was afraid I was going to have this problem. When my truck had about 1200 miles on it the oil level was high an smelled heavily of gas. I took it in to the dealer an I don't know if they changed it or just removed some but the got the level to normal full. I watched an it rose a little. I changed the oil an filter at 3400 miles. The oil level didn't climb again but it did have a slight gas smell. I'm over 10K now an haven't had a problem. I'm hoping it was just the rings seating an breaking in to the cylinder walls. Now I just check it every other week.

Dropped the truck off last week Monday. I have not heard from the Dealership since. On Friday, I got a call from the Ford Customer rep and was told the dealership is working with the Ford Engineer and Master Mechanic to diagnose the issue. I was told I would get a call on this coming Tuesday with an update. This is the 8th appointment I have had for this issue. I have inquired about a Buyback Replacement and I was told they are looking into it.

I got some paperwork in the mail yesterday from Ford, showing that they extended my warranty with a Premium plan ($100 deductible) to 75,000/5yr, which really doesn't do much for the engine issue, as I am on track to put 60,000 miles in 5 years and the standard powertrain warranty covers that. The brochure for the extended warranty, even Premium Care, shows that it does not cover everything the standard Powertrain warranty covers, heck the HPFP does not look like it is covered. So the extended warranty they added sounds nice, but does little for me. I am hoping the Buyback replacement is an option and, if not, that they actually fix it and give me some kind of assurance that any future related issues will be covered.

Why the hell isn't an engine swap even mentioned, is that beyond today's technicians capabilities . Doesn't make sense to me. Thanks for the reply, I hope it is resolved for you soon.Im in the 500 mile check routine again, this crap is disheartening!!

I just dropped my Ranger off today to have this looked at. Less than 5000 Miles and have been keeping an eye on the oil for the last 6 months. Level is up and smells like fuel. Service manager hadn't heard of the issue yet so I had to explain the whole scenario to him. It will be interesting to see what they come back with.

Wish me luck.

I have been following this thread and others, but have not read every single reply. Has anyone successfully had this issue resolved ?

Well After 2 weeks, I finally got my Ranger back and they claim that they did not find any issues. I will be sending an oil sample to blackstone for analysis and go from there. They did not change the oil and it still smells like gas.....

I brought that up with the service writer, and he told me he looked into it and that there is not a replacement engine available.

I wouldn't go by the smell so much, but by the oil level. Since March, my oil level goes up about a 1/10 of an inch every 50 miles on average. Injectors replaced twice, and HPFP and all fuel lines replaced once, made no difference. It seems that ambient temperature plays a role, as it seemed the level rose slower when it was very hot out, maybe just more burn off? It seems that the oil level will rise quickly to the max mark (hole) and then slower until about halfway between the max mark and the twist, and then it will start rising quickly. I am not sure, but I assume it has to do with the shape of the engine cavity?
