The OLM relies on both time and operating conditions to determine when to change the oil.

At one extreme, changing the oil and parking the car, the OLM will tick down to 0% at the end of one year.

At the other, a track weekend, the OLM will reach 0% over a few days.

At it's slowest rate, the former example, the OLM will tick down at a rate of 1.92% a week. Time is the only factor in this situation.

At it's fastest rate, the latter, RPM, operating temperature, duration of drive, etc., are a variety of factors used in the math.

I drove my scat pack very hard, but never had the olm come on before 5k miles. I didn’t use the paddle shifters as much tho, I don’t like speeding too much so I enjoy low gears and downshifting. I’ll go ahead and order the stuff and change it next weekend.
Driving hard means beating it up on the street or doing auto x or something?

Also the Dodge and Ford OLM aren't the same, of course.

As others have said, it also uses time as a basis for the calculations... It will actually tell you to change the oil after a year... with 0 miles.

4 months isnt too early to change it. Your driving habits will also affects oil life. If it says change it I would personally change it.

Stop making me Google KM and Celsius conversions man.

I'm doing you a favour. An active brain doesn't get alzheimers.
50kmh = 30mph
100kmh = 62mph
100C = 212F
An easy one 260kmh = 160mph
See the benefit of decimalisation Ryan? Our cars are 100 faster than your cars.

I did take a video of it, and it seems it did reset. I noticed last night my oil % dropped from 5% to 2% in my hour drive, so I really must be driving my car rough lol. I’m gonna lay off the paddle shifters.

So, why do most bike manufacturers recommend 10,000kms (6200 miles Ryan) for oil service when bikes are much harder on oils than cars, excepting original Minis.
Sport bikes wind to anywhere from 11,000 to 145,000 rpm, comp ratios are similar to the Coyote, oil capacity is usually around 3.8 - 4 litres (1 US gallon Ryan 😁 )
But the real oil killer is the bike engine oil lubricates the gearbox and wet clutch. Lots of severe shear forces, clutch wear material in the oil, etc.
And bike riders generally are harder on their bikes. We'd do track days and leave the oil for the next service.

The issue I have (call me paranoid) but if you go past the oil life and something happens to the motor will Ford deny claim.
