That's what mine says as well. Additionally, it states that of the oil life monitor fails then default to a 5K change cycle.
So, my questions now are: Does the 2013 manual say to dump at 7K religiously? Or, dump at 7K cycles if the OLM fails?
If any of the above questions are yes answers, will the 2011 / 2012 trucks be affected by the change?
