2022 EcoBoost Oil Analysis Shows >5% Fuel Dilution!

[Tim d]

So, recently did my second oil change on my 2022 EB. As you can see in the report, I was running AMSOIL Signature Series 100% Synthetic in 5w30. Run time on the oil was 5,600 miles. Note this change interval is WELL BELOW factory recommendation, and the onboard oil life meter indicated 50 percent oil life remaining.

All in report looks good EXCEPT the analysis shows a fuel dilution of greater than 5%, and SEVERELY low viscosity.

Anecdotally I can confirm the oil definitely had a strong fuel odor when emptied. So, not surprised by result. Question is, what to do? Obvious answer is shorten change interview to perhaps 4,000 miles and sample again.

But beyond that, any other recommendations? Catch can? Vented oil cap?

Please see full report attached.

Go by factory oil change interval and don't sweat it,that's what I've done for my last 2 dodges,had the last one 15 years no problems, current ram is 14 years old no problems,hoping to get at least another 6 years out of it. Hope my mav is this reliable!

oil minder in the Maverick only takes into consideration time and miles since the oil service was last reset. it's looking for 12 months or 10,000 miles.

I don't recommend 10k intervals but that's a whole different topic. my wife's Bronco easily hits the 12 months before 10k, so I've seen the life % drop as the year comes up.

ABSOLUTELY 100% FALSE!!!!!

Some gentle drivers the Oil Reminder has lasted 13,000 14,000 15,000 and one owner 18,000 miles.

Some heavy users the Oil Reminder has triggered off in 5,000 miles!

10,000 is what the average driver in average conditions can expect.
This is how the Hybrid works.

I have experienced this too. I have purposely not reset my oil change monitor and was notified 1,000 miles after to change the oil.

That is an assumption I don't agree with. Again, I have carefully "smelled" the oil ( as has he ) for ANY gasoline smell. Also the oil seems to be normal in that it does not seem to be thin as in it has lost viscosity.
Bottom line is that 5% fuel dilution is harmful to an engine. I have been around diesel engines most of my life and seen what harm can be done when you have high fuel dilution from a bad injector ( or more than one...).
My guess is that some of these 2% and higher fuel dilution cases are caused by shorter trips and colder weather might exacerbate that. Fuel can evaporate out of the oil to some degree when oil temps are at 200 F or so. But it takes quite a few miles of driving under a decent load ( not stop and go for 4 miles to work...) for the oil to reach those temps. Then it needs to stay there for a while to evaporate fuel and moisture. Because of this evaporation, oil maintaining a 5% solution of fuel means the engine has fuel bypassing the piston rings much of the time. That is NOT good!

So your assumption is correct, my assumption is not.

Got it!

Well you know what happens when you "assume"! Your statement, not mine, about being correct. Simple as that. Like I stated in first post here, Facts are facts and the OP had an oil analysis that contains facts. Facts like having 180K miles on an Ecoboost that shows no problems associated with fuel dilution is a fact. Your statements are opinions. And we know what they are like.....

While yours is "double" the accepted amount, you brought to light, in my Hybrid I fall into this category.

Many (almost all) short trips.
While the engine sometimes gets to full temperature, it does not sit there very long. I may be susceptible to gas dilution as well.

Hybrids are PFI. Complete different fuel system.

Your logic is flawed in saying an engine with 180k miles doesn't have fuel dilution simply because it has 180k miles on it.

OP does not have any problems associated with fuel dilution.

You have no factual knowledge that your son's engine doesn't experience fuel dilution because it has never been tested beyond your ultra precise sniffer and finger tips that measure viscosity.

Your ignorance is bliss and that is a good thing, otherwise you would be at the dealer getting new random injectors put in your EB because you had an oil analysis done......

If a high BMEP (boosted) engine has a fuel dilution problem it will not make 180,000 miles before spinning a rod bearing or other major failure.

Based on what OP has described his oil change behavior was - it is possible he had little to no dilution at all before changing his oil and only warming the vehicle briefly while idling.

The same dilution can easily occur on a vehicle with any mileage.

EDIT: My point was for OP not to freak out. Christian is a sensible guy so I don't think he will. I'm not arguing that 5% is not high and consistently it will cause issues with the engine.

Caution and monitoring vs. "my engine is broken and a ticking time bomb"

when he doesn't know this, it's not hard to realize he's also wrong about the ecoboost oil life monitor.

I have 30k on two MY2022 Ford ecoboost engines. They behave exactly the same. They show % against miles to 10k first, and then if you're not going to hit 10K before a year is up, you'll see the percentage of life change to reflect how much calendar time is left until 12 months has elapsed since last service.

I really don't know if hybrid is different and I don't care.

My 22 Bronco (2.3 EB) also behaved the same way.

I would love to have a Bronco!
Base model would suit me just fine!

I had a BaseSasquatch 4 dr in Eruption Green. Sold it due to a number of quality issues for a healthy profit > bought Model 3 (because my Maverick was not built) and drove it for 15 months, sold it for a loss nearly equal to the profit of the Bronco > Bought Tremor > still have 2024 Big Bend Sasquatch in Eruption Green on order.

We'll see what happens when it arrives - I really really love my Maverick. If I am going to spend another $20k to get into another Ford it will likely be an F-150 with a 5.0L and rear locker but Ford locks you out of 4A in the F150 unless you get Tremor, Lariat, or Raptor.

In the time that I ordered my Maverick and took delivery - I bought a 2022 Honda CRV Hybrid, 2022 Ford Bronco Sasquatch, 2022 Tesla Model 3....and ordered a 2024 Bronco.

EDIT: And of those - the CRV was the shittiest - even WITH the Bronco quality issues. Wife drives a 2018 Odyssey and we've had zero issues through 75k miles besides the sliding doors being replaced a half dozen times between both sides with recalls and breaking.

The CRV (Touring) was garbage build quality compared to the odyssey (EX-L) although it was 4 years newer and a higher trim level (CRV was fully loaded). To boot - it got AWFUL fuel economy. Worse than my Tremor on the highway (24-25mpg) and only in the low 30s in the city. Best I ever saw was 37mpg for 1 tank of all city driving.

I have a 2019 F150 reg cab LWB 5.0 with 3.55 electronic locking rear diff. I’ve had a few pretty cool cars in the past, most recently was a 2014 California Special 6 speed, 2006 LS2 GTO, 6 speed (bought new) and a used 2005 SRT 300C. My work truck would absolutely hang with my Mustang and my goat until 107 mph and probably put a few lengths on the 300. The 10 speed keeps it right in the meat of the power band, it will bark the tires on the 2-3 shift! It would rip the doors off of my old 428 CJ powered 72 F150.
l surprised a few people, in both F150’s
I love my Maverick too.
