Hello to everyone! Im sorry if my question is stupid but I need your help. I bought my 500 Turbo in USA and for now this beauty lives in Kyiv.

Unfortunately, I faced the problem of high oil consumption of oil. The consumption was about 2 liters per 4000 miles. Engine works perfect, there is no any smoke or oil drips on the engine. Now I pouring Selenia Star 5w-40. Maybe this oil doesnt fit for this engine?

What kind of oil is used in the American market?
