Oil consumption was 2 liters per 1000 km. I changed the oil, filled one can. Drove 500 km around the city. Oil consumption was 300 ml. I added a second can and went to Moscow. I didn’t have to add oil on the way, upon arrival in Moscow the dipstick showed half-level. That is, for 1500 km the consumption was only 500 ml. I’m shocked! Unfortunately, further observations are impossible, because the car has been sold.
