I sure would not be concerned about any engine using a quart in 6-7000 miles. My avalanche uses about 3/4 qt normal driving in 3000 and I am good with that. Never have changed the plugs in about 60K I put on it and the mileage stays the same, 16.5 - 17 mpg.
Working on a JD LA145 mower. It's getting a new drive belt and idlers, new idlers and blades for the deck. This is an 11 year old machine, but the hour meter only shows 186 hrs. (?) Looks like a new one.
2011 Dodge Journey that had a V-6. 15-16 was about it for that thing.

3.6?
Our journey had the 4 cylinder and it usually stayed near 22 to 23.
Our caravan has the 3.6 and gets anywhere from 20 to 30 mpg depending on what you are doing. Stop and go eats gas up pretty quick
