Were those done hot or cold? Did you mean, burning a quart in 2 miles or 2000 miles? You have almost 20 psi difference between some, which is a little beyond normal. But, if your valve adjustment isn't the same between all of the cylinders, it will change your compression readings.

One quart in 2000 miles isn't terribly bad, but I have seen much better. What are the details on the engine?
