2016 Silverado, 40K miles - no sign of a leak but somehow used 1.5 qts. in last 5500 miles, far more than my 2005 diesel

Any comments?????

Seems like my LB7 only uses oil when I tow heavy. Looks like it will be 2 qts. in 10K.

try owning a direct injection gas engine. oil consumption on most engines is normal for a quart every few thousand miles, or so the manufacturers say.

Could be one or more reasons, valve seals, piston rings, etc. But to be on the safe side check for oil in the turbo boost side, you don’t want to risk a run away. Could also be leaking on the exhaust side.
Any blue smoke?
