Hello. My Alto VXR 2008 has a problem that its engine oil is getting lesser in quantity. I am using Zic A as engine oil. local car mechanic says that its rings are weak and need to be replaced at an expense of 8000/-. I need your expert opinion on what should i do to replace the rings of my engine and disturb my engine. or problems can be solved without operation. any help in this regard will be appreciated.
