I see a lot of people getting oil samples tested and fuel content in oil has been a concern so I thought it might be nice to collect info and summarize. The most common oil test facility used is Blackstone Labs but there are others. A goal of this poll is to see how widespread the problem is and what averages are.
If you have had your oil tested, and that test reports fuel content as a percentage, please add yourself to this poll.
Oil test results, % fuel in oil:
<0.5%
0.5-1.0%
1.0-2.0%
2.0-3.0%
3.0-5.0%
5.0-10.0%
>10%
I think those ranges might be a good span from great to horrible, and range from no problem to keep an eye on it next oil change to you better do something NOW.
I know some conditions matter. If you've got many miles of hard towing, you can expect higher fuel content. Or even you're just "turbo happy." So I've allowed this poll to be updated with a second test if needed. For example, after fuel system repairs, or after different running conditions, or even after more mileage has been put on your truck, breaking in the piston rings a little better.
Reference discussions:
Fuel in Oil - Big discussion thread. Please continue discussion there about problems, solutions, etc.
Fuel in Oil Poll - Less technical poll based on smell and oil level in crankcase. Sound off there if you have an issue but no test to back it up.
For this thread, please only participate if you have had your oil tested, and maybe just limit discussion to your results and specific notes from Blackstone. Big battles with corporate Ford and your dealer regarding fuel content are probably better in held in the big discussion thread, where much discussion is already ongoing.
If anyone is wondering, my fuel content has been tested multiple times. Initial test was only .5%, highest fuel content was 2.8% after a winter of hard riding, and I average out in the 1-2% range over time. (My poll entry updated 03/11/22 with my overall seasonal average - those of you with multiple seasonal tests I recommend you enter an average also) Also no antifreeze or water content. Same highish copper everyone has on a low mile engine. My viscosity was still a little on the low side after 5000 miles so I'm glad I changed the oil and didn't wait for the engine oil monitor to tell me when to change it. Looking at the results, a 10,000 mile oil change interval for me would have been too long because my oil was already breaking down. Might have been due to warm up idling in the winter, or just due to a happy right foot and turbo. I don't go easy on this truck. Other details:
Average dailly drive 60 miles
Mostly highway driving
Auto stop-start disabled
Engine manufacture date Sept 19
Running 87 Oct w/10% ethanol
No lift kit or big tires
Occasionally warm up w/remote start
