when i put the new oil in i put 3 litres in then started the car to get the new oil around the oil filter then let the oil settle then i put more oil in until it was at the max mark. How much oil did it take the second time around to bring it up to max? Also in those 6 weeks how many miles did you cover and were most of them at high speeds? it took about half a litre i had dun abot 1500 miles
