salam, after buying cultus 2005/6 now car needs a change of engine oil. can you please suggest me which engine oil is best for cultus VXR? the previous owner was using Shell 10w-40 but my mechanic suggested me to use helix x5 yellow or helix x3 red gallon but 20w-50. my friends suggested me ZIC.
will be grateful to have your suggestions.
thank you.
