i think 5k miles is too much based on the look of the oil when i change it out.
im running mobil 1 with the same filter.
Thanks

NO, you do not need to. The OLM is based on a algorithm of things such as average engine speed, running temp, starting temp, average trip time, and so on. These are very accurate and GM actually states the average trigger is 7500-10000 miles.

BTW: There is no way you can judge your oil by the look. Unused oil in an open bottle will darken with time.
