What is the problem with my Honda City

[guruji]

If the exhaust is throwing Blue smoke what dose this indicate?

there is a very small vibration too in the car when i go over 100.

Are these two things connected?

in my observation the blue smoke is the coolant that is burning looks like there is a leak and its best to check engine ASAP

if the car is not taken care of that is serviced on time then this may happen. and also with time if the parts of the car are not changed then also this may happen.

blue smoke is not a good sign, you are not getting a full burn and it must be consuming lots of oil and fuel some times.
