2022 EcoBoost Oil Analysis Shows >5% Fuel Dilution!

[colinl]

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

base is gone, for now at least. it might come back next year- who knows.

Ford couldn't meet demand so they simplified a number of things for MY24.
- can't order Base
- can't order a 2 door Outer Banks (wagons only)
- if you order a 2.3 in higher trim levels you're forced into the 7MT; if you want the 10spd auto, you are forced into the 2.7
- high package cannot be ordered. Ford tries to obfuscate this by calling the lux package "high/lux" which is ridiculous- every package always builds upon the previous. high is gone, you get mid or lux.
- can't order advanced 4x4 separately any longer; only included in sasquatch, or Badlands
- cloth interiors are gone. everything is marine-grade vinyl or 'leather'
- brown interiors are gone, both the seat materials and the copper- or sand-colored dash and door panel trim.

here's my wife's '22. it hits many of those deletions as it's a 2 door Outer Banks with adv 4x4, 2.3 10AT, cloth roast interior. (rampage soft top added)

So I worked with an engineer that was a designer for one of the Big 3. At one time he was tasked with designing different shapes, depths and volumes of that little dish you see on GDI piston.
It’s called a cold start bowl, it’s main purpose is to try to deflect gasoline from spraying directly on the cylinder wall and lower cold start emissions. Even with this you can still see visible signs of wear on the cylinder wall opposite the injector on GDI engines after several hundred hours of testing on a dyno. This is part of the price you pay for such high output from these small very powerful engines.
Not too long ago, we were glad to get 250 hp and 300 lbs of tq out of a 5-5.7 liter V8. Now, we have engines half that size making the same or more horse power and torque.

I will miss the cloth seats for sure.

I had a 23' Black Diamond ordered as well with 4A and a 2.7 that I passed on because of the changes they made to MY24.

Decided to drop down to the Big Bend and Squatch it again (for 4A). I lost the 2.7 (which I really wanted) but I gained MGV (retained from my BD), 12" screen, Signature lighting, HOSS 3.0 Severe Duty Steering Rack, front locker, 35s, and Bilsteins (take em or leave em) for almost the same price as my MY23 BD.

I'm one of the few who benefitted from the MY24 changes - only thing I lost was the heated steering wheel on the Mid pkg but I will add that myself later on.

Giving that I had a diesel engine truck, some Injectors are known to occasionally leak fuel even when not operating. that for diesel engines. Not sure about gasoline engines, how injectors are built or operate.
I’ve read reports of DI engines do emit some soot when first started, as evidence of soot in the exhaust tailpipe. This prob means rich mixture to render easy start? And prob unburn fuel emitted. Or something like that.

IMHO, any fuel in lube oil a no no, tends to reduce the lubricity of lube oil.

Soot from a GDI engine is a real thing. Not just on cold starts but any time you get aggressive with the gas pedal. You can see it if you are following a vehicle with GDI when they accelerate hard. Europe has talked about or possibly implemented some form of particulate trap similar to what some diesels have on their GDI autos. Depending on what type of diesel injection system used (high pressure common rail or low pressure), you could experience a weeping injector. GDI oil dilution is normal and not related to a leaky injector. An occasional longer than normal trip is beneficial if you frequently make short trips to boil the gasoline out of the oil.

Sweet looking Bronco

That's EXACTLY what I did. Drove it up on some ramps and let the engine warm up for 5 minutes before draining.

So, it's entirely possible the level of fuel dilution in this report is somewhat misleading. That said, I am sure there is still plenty of fuel dilution in virtually all GDI engines.

Again, my point in sharing this report was not to give anyone a "sky is falling" sense of doom. Although a few folks who have responded here seem to think I should bring my truck to the local dealer immediately and demand they tear the engine apart and fix this, my guess is just about every Ford tech in the country would say "all the Ecoboost engines do that" and laugh.

IF -- and I stress IF -- I get repeated oil analysis <5% fuel dilution, I will certainly address the issue. However, I am not going to panic over one result. As I said, I'm going to shorten the oil change interval, run the engine longer/hotter before the next change and retest.

Then, we'll review the next result and evaluate next steps from there. I think making any kind of huge, definitive conclusions from a single data point is inconclusive at best. A reason for concern? Sure. A reason to panic? Not yet, IMO.

Bravo... How reasonable of you.

I love all the armchair analysis and subsequent bickering, makes for an amusing read.

 

[Timothyd]

Doubtful. In fact, I would be surprised if many Mavericks didn't return a similar result if tested. As the report says, high fuel dilution is common in direct injected engines.

I don't drive a ton. Making many short trips, where the engine doesn't get super hot, could contribute to this as less fuel may be burned off as it circulates through the engine.

I highly doubt there is any real problem with the issue, or short-term danger to its operation, which is perfect. My concern in testing/monitoring is more about long-term reliability of the engine, and I would think doing what I can to reduce fuel dilution will be beneficial for the long run.

I see some guys wanting to install a bigger turbocharger. This could make it worse.

Someone making you read this?

Please explain?

 

[colinl]

Please explain?

Sure. You see, he has absolutely no idea how a turbocharger or direct injection works. So he just threw something against the wall to see if it sticks.

 

[Timothyd]

Please explain?

Higher pressures in the combustion chamber will result in more blow-by of gasses and unburnt fuel and soot.

Please enlighten me. When you have a system and change/ improve only one element the design of the other elements are inadequate.

Typical forum troll. They never contribute anything worthwhile, just criticize and throw out anecdotal and sometimes plain wrong info.

Higher pressures in the combustion chamber will result in more blow-by of gasses and unburnt fuel and soot.

The major cause of GDI fuel dilution is not from blowby gases but from cold starts and questionable mixing in the combustion chamber.
This has nothing to do with the particular boosting system being used.
There is a fair amount of NA GDI engines in use today, do you think these are immune from gasoline/oil dilution? I don’t think so….
