Hello to all. Recently I bought 2008 MINI 1.4 petrol engine with 155 000 km. Engine is burning oil, I have to put 1 liter of oil on every 800-1000 km. Is this ‘’normal’’ thing on this motors, or there is something to check out like PCV valve or something like that? Should I try with different oil? Now is 5w30 in it, castrol. Any help or advice will be appreciated.
