How does the oil life monitor work? Does it go by the miles driven or does it actually sense whether the oil is dirty enough for changing? What % do you guys change the oil?
I do a lot of over the road, long distance driving, so I sometimes have to anticipate where I am going to be and change it early, sometimes as early as 20%. If I am going to be physically situated so that I am around town I run it to 0%. I normally use full synthetic as opposed to synthetic blend.How does the oil life monitor work?

I only do about 25% of the maintenance at the dealership and the rest is at home or local repair shops. Hard to keep track of 3 vehicles with +425,000 miles between them without having to write things down like was it a rotation or cross rotation 8 months ago? It is iPhone app that is synced to my Dropbox account called Road Trip: https://itunes.apple.com/us/app/road-trip-mpg/id298398207?mt=8mrgold35 - What app do you use to do this tracking?
My answer posted in the first response to this thread comes from a conversation I had with an engineer at the Chicago Auto Show circa 1998. I don't recall who all had MID's in place at that point, but Ford definitely did and you can bet every other auto maker that added it used the same type of logic and algorithms. Once an engine is warmed up and at it's normal operating temp very little wear occurs, especially cruising along at highway speed with the engine in the low 2000 rpm range. Add a towing scenario locking out O/D and bumping the rpm's into the low to mid 3000 range and the engine runs hotter naturally eating up the oil life faster. The ECM is programmed to keep track of all that and advance the MID schedule accordingly. Both simple and complex at the same time. During development they ran MID's in test track cars and tested oil samples on regular intervals to dial in the MID. Granted, auto manufacturers are always toeing the line between making the car last forever and wanting them to break so they can sell parts, service, and new cars.On my 2014 I hit 0% once on a coast to coast and back trip - it hit 0% at almost exactly 10,000 miles - so it seems to be about 10% per 1K miles give or take somewhat based on whatever variables they use in the equation, which I don't think any of us here actually know.
Why is your oil life dropping so quickly? Do you do unusual driving? Is this on a 3rd gen or is it on a 2nd gen?I just keep resetting the MID every time it showed 10% oil life without changing oil until 10,000 mile with m1 synthetic. I probably had to reset 3 times without changing oil.
It is 2200 miles since last oil change and it’s at 40% oil life
Oil consumption is a symptom of motor issues. Could be anything from valve seals to rings. But guaranteed, you have motor problems.2011 mdx advance. Have oil consumption issue. I have to top off about 1/2 quart for every 1000th mile to bring the oil back to the top line. And I drive for Lyft & Uber full time. That is the reason the oil life is accelerating so fast.
