I've noticed a steady increase in oil burning over past couple years. 1200-1300 miles between adding quarts a couple years ago to now 700. What are the most likely suspects? Seems to be more consumption/burning than leaking while idle because at one point recently it was not driven for awhile and I noticed no change in oil level at all. Plus this decrease in oil efficiency has been remarkably steady and gradual.
