Fuel in oil

[Langwilliams]

After my local dealer refused to do anything about my reported oil dilution issue, I spent a few hours talking to Ford Customer Service about what, if anything, Ford was prepared to do. The final answer is, they will not do anything about it. They will not pay for an oil analysis.

Looking at your analysis reports I wouldn't worry about being a little over the 2% blackstone uses. I've seen on other sites (maybe bob is the oil guy) that 2% is an older standard from before direct injection an under 5% is a more realistic standard for DI motors. Just keep up the 5K oil changes.

My results at 10K miles from blackstone was 2.8. They told me that is high. The fuel also thinned out my oil (obviously). My truck is used on the highway 90% of the time.

How much does this analysis cost to be done? Want to know what mine is but kinda don't at the same time

For Blackstone, a basic analysis (including fuel%) is $30. TBN is an extra add-on, but completely unnecessary if you're just wondering about fuel and wear metals.

After my first analysis, I e-mailed Blackstone to ask about the 2% limit and whether that was relevant to DI. The guy who responded said the 2% is somewhat arbitrary and is based on what they typically see across all vehicles, and also that they don't see much difference in DI engines.

Last night I checked the oil in my new '21 XLT. Reeked of gas in oil. 2600 miles on the odometer.
My '19 never did and I traded it at just over 30K miles.
I drive the same routes daily as before. Literally nothing has changed in my routine for both vehicles...25 miles each way on workdays (currently 6 days a week), mostly freeway miles at 69-70 mph. I warm up each morning until the idle backs down and then just ease through my neighborhood streets until out on the freeway. By the time I get to the freeway the temp gauge is moving up normally.

I am confused as to why this is, and am just unable to read through 137 other pages on this thread (although I did read the first couple or so and saw a lot about catch-cans).

Because you guys know stuff and I don't, is there any special task I need to have performed soon (early oil change, or something else)? I normally have the dealer do oil changes every 5K miles.

Thanks in advance for your patience and advice.

-Monitor dipstick levels; if your truck is consistently "making oil," get it into the dealer to check for injector/HPFP issues
-Consider sending a sample out for analysis. "Lab analysis says I have XX% fuel dilution" will do more to get a dealer's attention than "My nose says there's fuel in my oil"
-If you're getting some fuel in the oil, but Ford continues to say the truck is operating as designed, keep oil change intervals short and use a high quality oil to ensure that you maintain good lubrication. At 5k miles, you're already doing the changes twice as frequent as dictated by the manual, so your SOP is probably fine.

-If the dipstick isn't rising and/or your reports are coming back at <2%, congratulate yourself for having a sensitive nose, and just go drive your truck without worry!

Let it break in before you freak out. Let the rings seal. I'd change the oil soon with synthetic blend again then go to full synthetic on the next change. I'm old school in thinking pure synthetic doesn't allow break in as well an blend or conventional. I had the smell an high oil level early on. I did this an it went away an my oil analysis at 18K was 1.5%. I don't know if break in procedure helped or not but it worked out in my case.

Interesting. Just to understand more, why do you think it's better?
I kept the stock oil until 2.5 k miles, and then changed to full synthetic.

I agree with something I read a long time ago about that full synthetic is too slick for the rings to get any wear on the piston walls to seat/seal. After that it's better. It's the old school thinking but I follow it.

I do too ..

Thank you. According to that principal, how long should someone wait before going to synthetic?

I did the first change at just over 3K. Did another blend change to 8K then went full synthetic. If I still had a strong fuel smell at 8K I would have done another blend change but I'm no expert. Changing at 3K might have been ok I just disagree with buys changing to full synthetic at a thousand miles or so. I also made an effort to get some time in higher rpm's to break stuff in after the thousand mile mark.

What kind of oil comes in the engine from the factory? Also does anyone know what dealerships use when getting oil changed at dealer?

 

[Aonarch]

My brand new 21 Tremor has high oil level and it smells like fuel.

< 200 miles

I'll be switching out to Pennzoil Ultra Platinum at 1,000 miles.

Keeping an eye on it.

I also ordered the UPR crank case breather. I'm curious if that will help.

Without reading 100 pages, is there a tried and true solution here?
