Oil change?

Hello guys, So now it’s time – in 1500 km the service is due… This time I will make the oil change myself. I have already added the vacuum oil extraction pump recommended here in the forum as well as the mobile 1 0W-40 oil…. I will drain the old oil through the oil measuring rod opening. Just one more question so that I can get out really all the used oil. Is it OK if the car is horizontal to the suction or should I strive for any inclination (e.g. slight inclination to vo Rne right, since the oil rod is on the front right) – I want to make sure that I get the whole old oil and the mud out. Plan the following procedure: – completely drain old oil. – Change oil filter (tunes the order ?) – empty 2 liters of mobile. – drain again to get the complete dirt out. – fill in the remaining 8 liters (have two 5 liter canisters) … Does this fit like this? According to the operating instructions, the filling quantity is 8 liters.
