How much oil loss is normal?

It is a fact that most engines will burn some oil. The majority of manufacturers consider one quart of oil in the range of 1,500 miles to be acceptable.

At what mileage do cars start leaking oil?

But with time and high mileage (especially over 100,000 miles), valve seals and piston oil rings get hard and lose their ability to hold the oil. An oil filter that is not seated properly or an oil drain plug that is left loose (or even worse, over-tightened!) can leak.
