Thanks for your advice Mike.
Good explanation.. by the way speaking of blue smoke, how suppose we know that the smoke we normally seen during the very first start in the morning is not the bad sign one?
Say if something is bad on the engine, how can we typically observe or judge on the smoke (color, intensity, time duration, smell etc)
Hi Mike.. the blue smoke still can be seen even when the car has start moving (I watched the car from behind when my wife drove the car away). Initially I thought it possibly due to the exhaust gas being evaporated due to colder temperature at surrounding..
But when you mentioned there's possibility of sign of piston ring worn out..that's quite scary.. therefore
1. Do you have recommendation on what suppose I do?
2. What could be the cost to solve this issue?
3. If it is normal that 1 liter oil of every 1000miles, then I guess no action to be taken
