Oil life Monitoring Issue

[scazea]

So it looks like your 2020 Mustang was an Ecoboost per your signature? So your EB used oil as well? I don't think I've ever owned a car that used oil especially not a brand new car but I guess that's the nature of the beast (Coyote)? I sure hope I'm not buying a bunch of issues when I purchase this 24 GT. I just want something I can enjoy for 10 or more years without having to worry about a bunch of issues.

Well, Ford charged me for Oil change every time i service my 2020 Ecoboost....so yeah, it uses oil too! i had that car for 3 years, and when i change it for this one, it rode and look just like the first day! it was hard to part ways.....until I heard the engine on the 2024 GT.....then i was , Eco who??
I'm not a gear guy, i mean, i don't know much about car engine internals, just know what i like...but i was told that the GT is more robust than the Ecoboost, specially if you plan to have it for long...but don't take my word for that...

Thanks Skye, got it

Don't have a 2024, but everyone's cars here still seem pretty new, not a lot of mileage - one thing this could be, is Ford built-in an "accelerated oil life decrease" when the cars are new and still have low mileage. I've seen Honda does this with their newer vehicles (they have an OLM also, similar to the ones in these cars).

Reason? I think some of the OEs (including Ford) are finally on-side with trying to get that factory fill oil out of the engine sooner rather than later. In the Hondas, from what I've seen, when the car is factory new, the oil life decreases % much quicker than after you get the first oil change performed, and OLM reset. From the first reset onward, it's "normal" monitoring and decrease rate. There is nothing stated in the owners literature about this.

I wonder if Ford has stated anything to this effect in the owner's literature of these Mustangs, but I doubt it. In these S650 cars, I wonder if the behaviour is similar to Hondas, or if the "quickest" rate of decrease is when new; it slows down after oil change 1; and slower still after oil change 2; and then finally, it's BAU for the rest of the life of the vehicle.

Ford reads these forums. Maybe they’ll respond

JimC did you notice any reduction of the Coyote valve train tick by using the full synthetic?

I haven't really noticed the "tick" at all even before the oil change. Might be my bad hearing

Somebody else on here had exactly the same problem. Seems the IOLM is buggy on some cars.

They replay in typical bot format …doubt they are even real

I had the same thing on my car. Changed oil at 5,000 miles and last week noticed after only 1,000 miles I am at 39% oil life.

I thought maybe the update when I changed oil didn't take and I hadn't noticed it at the time. Although I was pretty sure that I checked it later that day and it showed 100% oil life and several days later showed 99% - but I was doubting myself on if I was remembering it correctly. With someone else having the same experience it must be some glitch.

I used full synthentic on the change.

The Ford dealership I use always show the Reset after they change the oil.
The vehicle owner has to change it to a normal screen.
Then you know the oil has been changed.
If this makes any sense?

I understand what you are saying.

But in my case I changed the oil life monitor myself after the oil was changed; I went to the local change place where you sit in the car while it is changed and not the dealer. It wasn't left on the reset screen, I went to the reset screen and did the reset when the oil change was finished. Yet about 1,100 miles later I am down to 35% oil life.

That’s what I’m taking about. I’m going to the dealer to have it looked at. I’ll keep you posted

YMMV I have a PP 24 GT bought in Oct 2023

1653 on odometer, oil life says 67% remaining.

Spot on. Mileage is low so time will be the main factor, 4 months is 1/3 year

The automated oil life reporting mechanism is crapola in any car for that matter. It does no oil quality analysis on the fly to give you a “realistic and pragmatic” rating. If you love your baby too much and don’t track her at all - full synthetic oil change every 3500 miles. If you track her / post 8 sessions(2 track days) oil change.
Btw / once you go full synthetic - don’t bother changing it to anything else.

Because the Gen. 4, 5.0 Coyote engine has a 10 quart oil pan.
Are the oil changing places doing 8, 9, or the proper 10 quart oil change?
Seems like a lot of inconsistencies with oil changes In the New Gen. 4 Coyote engines?
