Have you had an oil change, or are you on the factory fill? Oil usage on the LM2 during break-in is normal, such that GM adds an extra quart of oil in the factory fill. Assuming most people will go to the end of the OLM for their first oil change, that extra quart is added so it doesn't get too low with the oil usage during break-in.5800
I did an "early" first oil change on mine (1300 miles) and noticed the level down a bit on the dipstick at the time of the change. I then ran my second oil change out ~4500 miles on the oil and did not notice any oil usage. Recently we towed with it and I noticed the level down one section of "diamonds" on the dipstick, but I think that's pretty acceptable, especially on a turbo engine that is constantly at elevated boost levels.
