I have a 2021 Yukon SLE 5.3L that is telling me that my oil life is low and it needs to be changed. It only has 3400 miles on it and doesn't have much idling time. With the Dexos oil I thought it was calibrated for 6000 miles. I've had a '19 Yukon and a '16 Silverado that oil was changed at dealer every 6k miles with Dexos and never got a low oil life message. Did something change in the newer models?
