What separates a car that burns 1 quart every 2000 miles (mine just did - I had to refill it today) from a car that burns 0 quarts every 15,000 miles?
* Engineering design
* Manufacturing tolerances
Nothing else needs to be said. There is no arguing about it, like you stated. It's a fact that one or both of the above factors was not a priority with the Z. I love my car, but the fact that it burns 1 quart of oil every 2000 miles, and this appears to be common, says something pretty profound about the engine either from a design or manufacturing (or both) perspective.
