That's correct.Nothing monitors the oil, so the 'OLM' acronym is deceiving. There's no oil sensor anywhere; that's why you have to reset it (otherwise it'd reset itself with new oil). It's just an algorithm that basically does a combination of 3 things: Oil life goes from 100% to 0% in 365 days. Oil life goes from 100% to 0% in 10,000 miles max. And the third affects how much quicker life is reduced from 10K miles depending on how you drive. But even if you don't drive at all, the oil life would be 0% in a year, due to the calendar part alone (can't change that). Hope this helps.
I wonder if we can also use this as an indication of how "healthy" our driving style is. I mean, if you see that the current percentage corresponds almost exactly to the calendar, does this mean that no extra deterioration has been induced by your driving style - ergo, your driving is fine?
Of course, I'm not talking about a car that's been stored for months - in which case it's obvious that only the calendar will be considered. I'm talking about a car that's driven daily.
I've just checked mine, and the oil life matches the calendar exactly.
FordPass shows 58% remaining oil life.
I picked up the car on the 12th of October last year. So it's five months and a few days old.
5/12 = 41.6666666 %
100 - 41.666666 = 58.333334
