I had the first oil change down on my 16 Lariat EB at 7800 miles. It was filled with Mobil 1 synthetic extended life. With 10k oil change intervals the sticker applied by the dealer shows the next change at 17,800. However yesterday at 14,700 the service soon light came on and the oil life indicator sjhows 5% left.
Question: When the OLI (which is partly mileage driven) is reset is there a standard setting fro the oil life or is it programmed? Seems odd to have it come on so soon

The truck is equipped with intelligent oil life monitoring. When the truck asks for the oil to be changed, you should change it.

The truck is taking into account usage and other conditions. The days of changing based on a milage estimate are over.

My truck has 56K on it and has had 10 oil and filter changes.

And you can read more in your manual.

I always check when I have it done by a dealer to make sure it's been reset properly. It can be reset to 100%, 90%, 80%, ... So an unscrupulous dealer could set it to 50% and then get more oil changes out of a customer.

LOL

Do you think dealers make a bunch of money off oil changes? I'd be happier if I never saw another customer come in just for an oil change again. I'd rather deal with warranty issues all day.

Time invested vs. money made on an oil change or Works service is awful for us dealership employees.

It just resets to "100%" and starts counting down from there. You can see where it is reset on your instrument cluster menu if you look for it.

It's based on the standard fill oil, which is the motorcraft oils as listed in the owners manual.

"Intelligent" is a relative term here. It has no idea what oil you put in it, but it does "run the clock" faster or slower depending on your usage.

For example: hook up a trailer, the truck knows and applies an algorithm that run the percentage down faster. Same with short trips, etc...

Except....

At one year, regardless of mileage it will tell us to change our oil.
At 10,000 miles it will tell us to change our oil.
The olm has no idea what oil is in it. The cheapest garbage to the best synthetic. Has no idea we've maxed out our payload carrying around a bed full of rocks adding to the "work load". No idea how heavy the trailer is.... I'll throw in an "etc. etc".

I'll give the olm credit as making a reasonable guess at when best to change the oil and reminding us most importantly.

Should be named the OCR. Oil Change Reminder. The day when the olm does it's own oil analysis that will be different but at this point it isn't that "intelligent".

Change your oil at the very least when reminded. Change it sooner if that's your preference.

For those that want to jump down my throat for my opinion after talking about it with a 100 different techs ranging from very young to very old, this is "my opinion". Please save your attempts to discredit me as I really don't care if you do or don't agree with me.

YMMV

Which is why I bring mine in to the dealer. I pay the same for an oil change if I do it myself or bring it to the dealer. I can see where it would **** a tech off.

I've had too many screw ups, slips, and just dishonest people from local shops and dealers, I just do it myself its too easy not to.


But I just did my oil change, full synthetic and I set it to 75% life when I did my reset. Why? like I said, oil change is cheap and easy and its just piece of mind (and an excuse to crack open a beer and crawl under the truck)

My intent is not to jump down your throat, but I will point out that the truck does monitor load. Not in the common sense of weight in the bed, but it monitors load on the engine.

It's displayed on a live data monitor as "% load" usually. It's there on my 2016 F150, I just can't remember the exact terminology it used. It's been there since pretty much the beginning of EFI, I've used in in "tuning" everything from obd I systems on up. Gas and Diesel.

I usually click it on when running a datalog. It's just another parameter to overlay on the graph when I'm checking how the engine is running after an adjustment. It's not really useful to me on it's own, but when comparing successive runs it gives me a better feel of overall engine performance, when taken in consideration with the other parameters I log.



So while it may not "know" how much more weight you have in the bed, it does "know" how much more throttle you are using to get it (and keep it) rolling. Same as temps and speeds.

Trailer starts with the "smart trailer" hook up thingy, in addition to the % load numbers and vehicle temps, speeds, etc. So it may not know how heavy your trailer is, but it doesn't need to. It just needs to know there is one and how it is affecting the engine parameters.

Granted, I haven't seen the code for the OLM, but I would be very surprised if it didn't make use of the % load PID. seems to me that (and temps) would be the most accurate way to count down the life cycle of the oil based on useage.

Like I said: not looking to discredit, just trying to have a polite discussion and pointing out what is happening inside the PCM in different vehicle uses...

You are correct about the 10,000 1 year thing, says so right in the manual. Also agree that it doesn't know what type of oil is in there. But that's where the "intelligence" of the owner comes into play: put at least the spec'd stuff in it, or better.
