Do EcoBoost engines accumulate contaminants faster/differantly than naturally aspirated engines?

    Do EcoBoost engines accumulate contaminants in the engine oil faster/differantly than naturally aspirated engines?

    As of today, 11/17/19, our ’19 Explorer with the 3.5L EcoBoost has 9,100 miles on it. I’ve changed oil using 5W30 Mobil1 Synthetic and Motorcraft FL500S oil filters at the following mileage intervals:
    - 1,040
    - 4,100
    - 6,500

    Even a few hundred miles after the oil change, I'm suprised how "dark" the engine oil is.
    This is the first TT vehicle we’ve ever owned.

    It runs fine, I have no reason to believe there are any issues. Maybe it’s me...

    Maybe I should send a sample to Blackstone Labs for analysis?

    I ran amsoil signature series in my '13 explorer sport with the 3.5EB. I ran the oil about 10k miles and sent samples off to Blackstone. Never had any bad reports. They said it was actually good for a few more miles.

    Oil is made to carry dirt. Dark oil on a high quality oil does not mean it is not protecting.

    The only way to know is to test it. Then you'll know how far to go in the future.

    Try the M1 Extended performance next time, true synthetic oil

    I only run mobil 1 extended range full synthetic in my 2.7 TT F150. its supposed to be good for 15K and I usually change it when the computer tells me to which ends up being around 9K i think. 55K and still going strong. i pulled the FMIC off the other day to check it and nothing more than some residue was inside.

    I'm more concerned with fuel dilution on EB engines than dirt (solid combustion products). If you want to try oil analysis, this is a pretty good deal:

    DI engines seem to have a tendency to dirty up oil really quickly.

    DI engines are much harder on oil. They also are known for valve coking. I think the newer 5.0 engines have port injection and direct injection now. The port injection is there to help keep the valves clean.

    Also, oil companies have started to develop oil specifically for direct injection engines here in the past year or two.

    IIRC, port injection has benefits at idle and low throttle applications as well. Something about the tumbling of the air helps atomize/mix the fuel in the runners prior to the combustion chamber.

    At RPM/heavy throttle is where DI has an advantage.

    It's essentially the reason that EcoBoost engines don't have to run a GPF (gasoline particulate filter) in the near future.

    Well, it goes like this: everyone knows that diesel engines turn the oil black because of soot. Until DI gas engines came along, we all thought it was because diesel didn't burn clean. Now, we realize it's because DI engines make soot, regardless of what they're burning.

    My family fleet has two DI engines - a 2 liter BMW turbo and a 3.5EB. Both have black oil fairly early on, and I change both twice a year regardless of mileage. No indication that soot causes any problems.

    No fuel filter on my 2.7 150.

    You would think you would still want a fuel filter to prevent contaminants damaging the injectors.

    I'm talking about an emissions after treatment system. Not a regular fuel filter.

    It's on the fuel pump as a "life time" feature. So high mileage trucks, you'll want to drop the tank to service.

    I have seen companies state it would be nice to put a very fine filter inline somewhere due to the HPFP and DI injectors having very very tight tolerances.

    Again, if you run a high quality oil, the black is not an issue...oil analysis will prove this. Amsoil.

    Been doing the same here on my 144k mile 2004 Ranger. Amazon 5w30 synthetic. I change it every 4k and my truck doesn't burn a drop of oil.
