My car has 2 years extended warranty left. For some reason I would like to have the next service done at a private Maruti Authorised Workshop rather than the dealer. Would it render the warranty void?
I need to change my engine oil of Swift Zxi 2012 model. I was using Castrol magnatec till now, someone suggested me Total 7000 grade oil for better performance, is it good? It comes with specification 10W40 instead of 5W30 recommended by Maruti, will that harm anyway the engine?
