Tough question, it depends on the engine, the age, and usage, and maybe the karma of the driver.
Back in the stone age (1968) We had a customer that had a slant 6 Dodge Dart. We would change his oil and put in 4 quarts. The sump held 4.5 so he drove 1/2 quart down. 3,500 miles later he would be 1 full quart down (burned off the other 1/2 quart) and we would change his oil. Back then that was almost unheard oil mileage.
Nowadays, it is not unusual to not even go though a full quart between service depending on the car and it uses. I had one company car with a 10,000 oil change interval, and it would use just under one quart in 10,000 miles. Most of my cars use about 1 quart every 5,000-7,500 miles.
Part of the problem with coming up with what is normal, is that I could have you drive one of my cars and you might use twice the oil that I do due to your different driving styles, or types of trips you do.
Also you need to pay attention to how the car maker recommends you check the oil. If you do it the wrong way, you might see a 1/2-3/4 of a quart too low of a reading. :eek: Read your manual for the correct method, or if possible park your car on a level surface and leave it there overnight. Check the oil before starting the next AM. This will be the most accurate method short of draining the oil and weighing it. :eek: Yes that is done sometimes to verify oil usage.
