I have an audi 100 S4 V8 (ABH motor) and the engine consume too much oil (1 L for 200 km) The car as 200 000 km !
there is no blue or white smoke.. just a light black smoke on strong acceleration But there is oil which go out at exhaust.... So i think the oil isn't burned..... i have not yet verified the state of spark plugs .. i think it is the valve seals...
What do you think of my problem (piston rings ? something else ?)
