I always change the oil filter at around 55-60%. The way it is written in the manual it is hard to interpret. It says if you use Dexos1 to change the oil and filter at 3000 miles and disregard oil monitor. Then it says if you use full synthetic to change oil soon after 10%. It doesn't say not to change the filter still at 3000 miles. Mine at 55% is at about 3000 miles so I change the filter which I did a couple of weeks ago. Filter was pretty black then, it must be plugged at 7200 miles especially if it still had Dexos 1 in it. This is just my opinion though, not the holy grail.Took my Trax in for its first service today at 7,198 miles, oil life at 9%. If I didn't have that trip to Philadelphia, I might have made it to the new year.
