Friends, i used ZIC 20-50 engine oil and it killed my 2010 xli engine after oil pump stop working making sound like diesel engine , my car has 126,000 mileage and through out petrol run, after consulting with mechanic he has overhaul engine with all new valve and other parts, someone is suggesting that engine condition will start trouble after six months after rebuild or so and it will not be good as Qabli engine, but mechanic is suggesting that he is rebuilding engine every week, my car will be trouble free for at least 2 years, please recommend that
shall I sell my car?please advise , thanks in Advance.
