I was wondering, i have an appointment for next week, but since my last oil change, 5000km, i have had to put 2 full can of oil in the speed, i can't see where it goes, since it's at least 2-3 time more than i'm used to add, someone have experience this before, maybe the car smokes blue but i did not notice so far, wondering if someone can maybe tell me my problem, no spilling anywhere
