I observed burnt oil traces infact much more than traces, you can say black oil is throwing from my Silencer since last week.
Consequently, engine oil level is also decreasing as observed on dipstick.
Engine noise also seems little increased as compared to before.
White smoke is coming when it is driven on petrol but smoke gets controlled as soon as I shift it on cng.. Also there is some sort of missing(Type of stalling)
Oil change is due since long & it was delayed.. Plus mechanic poured open oil from drum last time.. YES but now why so much amount of oil is throwing from silencer.
Is Engine fail warning is awaiting or what is this?
