I added new oil and Lucas oil leak sealant to the car, and shot out dense blue white smoke. I've removed the oil with Lucas and added new oil, but car still shakes and blows out blue white smoke.

Hi,

Did this just start since the oil change? I'm asking because blue smoke indicates oil burning and white is usually engine coolant being burned in the combustion chamber.

Let me know. Also, if you could video what you are seeing, it may help me.

Take care and let me know if there were any problems prior to the oil change. Why was the leak stop installed (where was it leaking)?
