Engine Oil turned black just in 15 days in my pulsar and level low too

Friends

I have Pulsar 150cc and its 10 months old. I had replaced my oil 15 days back but engine oil is turned so black in 15 days and oil level is also decreased.


Please help me.

Most probably ring-piston is damaged and reason could be using wrong grade oil or simply using duplicate oil. But before concluding anything, first change oil and get it from some reliable shop or service center and see if oil level steep dips. Also see if there is any visible smoke coming out of bike.
