Oil Life Percentage
I'm still learning my new to me 2010 F150, and something I just discovered last night was that if I press the odometer control stick (whatever it's called), I can cycle through some options, one of them being system check. Upon doing this I saw that one of the things it told me was, "Oil Life: 16%". I'm assuming it's counting down, right? Rather than counting up - it's not saying that I'm 16% into this oil life cycle, but rather I have 16% left, right?
The owner's manual said to change the oil every 7,500 miles or 12 months (I was surprised at how long it recommended). So I'm assuming that upon a reset of that gauge, it counts down to whichever comes first? Just want to make sure I'm reading it correctly. I had assumed that the dealership I got it from a couple weeks ago would have changed the oil (they're a reputable nationwide dealership), so I was surprised to see it at 16% and it not be higher. But, then again, they could have simply not reset the gauge. I don't think it actually detects the health of the oil ... But I could be wrong.
Thanks for any clarification!

speaking of, I just changed mine at 5k miles, oil life was at 50%, did I just waste money? I'm not one to waste money, but I am one to maintain my vehicle, I guess as much as these trucks cost, we can trust this oil life feature to be accurate, right?

No one has posted, beyond gas dilution issues, any oil test results that show that changing before 10,000 miles (one of the two upper limits on the IOLM - the other is time, 1 year). In fact, tests at 10,000 miles show plenty of life remaining for many.

Fun fact - next oil change set the IOLM to 90% instead of 100%, and it will go off when you want (at 10% of 100% life, i.e. 90% used).

Ford dealer here says ALL cars, ALL engines are ALWAYS used in "severe" conditions. (because it gets cold in MN sometimes) So, they recommend things based on the severe chart. And, of course, their chart is more stringent than the actual chart in the manual.
But, the IOLM has NEVER given me less than 10000 miles between oil changes. I've been doing them around 7-8000 by choice. Point is, all those other items djfllmn mentions are not affecting MY truck's calc, despite living in MN.

They're focused on maximizing revenues for them. And their chart, as you note, doesn't follow Ford's anyway, so they didn't follow Ford's January 2017 memo telling them to cut the garbage and stop recommending unnecessary services.

There's a reason some shops charge $15.95 for an oil change and others charge $80, not all oils and filters are the same, there's more to oil than just the viscosity.
