First UOA I've ever done, figured I'd make an account and share my results:
0w-20 Factory Oil
2840mi
2015 Silverado 4x4 LT 5.3L
~3 Months in service, First 1K miles gentle and mild to hard after that. Weather was extreme changes from 70F one day to 30F the next (Michigan is awesome...).
Switched to Mobile 1 0w-20 AFE and Royal Purple 20-500 Oil Filter; Probably going to do a UOA again in another 5K just to compare and then gradually try to get up to 10-15K depending on TBN/wear.
