Ben,

The oil consumption rate you describe is about a quart in 3,600 miles. This is not oil consumption. I would expect that this is about the oil consumption rate of these engines when new.

Excessive oil consumption worth concern is when it drops below about 1,000 or 1,200 miles per quart. Even then, these engines will run many, many miles if kept full of oil and changed regularly.\

Keep climbing the hills, check the oil, keep it from dropping below the add mark and enjoy yourself and your car.

Have agreat day,
