Check your oil pan to see if there is any oil residue or dirt stuck onto the sides and/or bottom. I have had 2 separate oil pan bolts become slightly lose (felt about finger tight when I put a socket on them, one on each side) which caused a bit of oil seepage at different times about a year apart requiring me to add over half of a quart of oil each time after tightening them back up which stopped the oil consumption both times.
Maybe it was caused by the vibrations from using curbs on tracks but it does not seem to be a common issue with the 6th gen Camaro.
