Yes it can, however I didn't have that particular test done, because I don't do extended change intervals, and it's an additional charge to have done. Down at the bottom of the report on the left side, you will see TBN. If you have that test done, it will tell you how much more life is in your oil at what mileage you did the sample at. It will tell you that you can either go longer on your next oil change, or you went to long.
