Cars consume engine oil, but oil consumption is minimal.
Note that the amount of engine oil your car consumes will depend on viscosity, quality of the oil and the way you drive your car.
Your car consumes engine oil when you drive at high speeds and also frequent acceleration and deceleration.
A new engine consumes engine oil.
Normally your car should consume about one liter of engine oil every 1000km (600 miles).
If your car consumes much more then have it checked by a qualified personnel.
You should also note that engine oil drops on the floor under the car and oil stains on the engine body need to checked by qualified personnel.
