I have a pulsar motor bike and I don’t know when I need to change new bike engine oil. Is there any symptoms in the bike which will indicate that I should change the old engine oil ? What will happen, if I just ride the motorcycle without changing the oil for a long time? Can I add the new engine oil with the old one or the old engine oil must be cleaned for poring the new engine oil?
Its good to change the engine oil at least once per 3 months but it actually depends upon how much kilometer that you have driven your motor bike. If you drive your vehicle in full speed then your engine oil will evaporate and become blacky pretty soon. The sound of your two wheeler is also a good indication to change the oil, if it doesn’t sound good then its something with the engine oil or with your engine.
New engines are capable of running with the same engine oil for a longer time than the old engines. You must remove the old oil fully before poring the new engine oil. If you run your bike without changing the oil for a long time then it will affect your engine, it can even result in engine gets cheesed off!
