So ive had my 2006 denali for a little over 3 months now and its time for its first oil change. My oil change % is about 45% right now and there is roughly 3000 miles since its last change. When i change my oil this week how do I reset that counter? also how can I change the distance so the light comes on after roughly 3000 miles?

Not sure how often gm recomends changing the oil in the 6.0l but I dont drive much anymore and if I go 5k between changes were looking at over 6 months of oil.
