black smoke form the exhasust

[nikunj]

my nissan GT-R was a gift from dad and i am very happy with the car but recently i had got it service and soon after that there was black smoke coming out of the exhaust which is a big concern if they have used a compromised product for the car.

when i checked with them they said it will go off in a day or two

it that so or i need to act fast before it causes any major problem

please help

If it doesnt go in less than 20 km drive, get worried and remove the engine oil. its an expensive car and if some moron must have put normal oil then it might be big problem. Better get to Nissan and let them handle it that way it needs to be treated.
