That may very well be, but the 2012 Focus isn't running a full synthetic oil and also that the manual specifically outlines 10,000 as the longest interval for oil.
My personal car maintenance philosophy is to maintain the car, but not over- or under- maintain. I changed my oil on my last car every 7,500 miles as per the owner's manual and got the car up to 170k before I sold it.
I actually have faith in the iOLM technology, but I'm concerned that there's no way to see the current oil life. Maybe I just don't like surprises, but I'd rather know that I'm down to 30% oil life so I can figure out when to make time to take the car in for service, versus having the 5% "Oil Change Soon" surprise me.
