I serviced my car last week after I have noticed the blue smoke coming out of exhaust after starting. When driving it be like the turbo is under pressure when it releases the smoke will be too much. I have used the Castrol magnetic oil. 10w-40A

Hello,

Was the turbo put on as an aftermarket unit, or did it come from the factory that way? Anyway, blue smoke from the exhaust usually means that you are burning oil in your vehicle's engines combustion chambers. Here is a link to a generic guide explaining what's going on below:

Since you have a turbo on your vehicle, though, I would look at the output shaft seal as it could have failed. This seal is responsible for keeping the engine oil in the gear case of your turbocharger and when it fails it will allow oil into the volute and compress it with the incoming air entering into your engine, where it will be burnt with the air charge causing the blue smoke. Unfortunately we do not have a guide on how to fix this, but this is what is going on. I hope this helps.

Thanks,
Alex
