weird smoke.

I was topping up the oil this morning, and the car has not been running for all of 4 seconds that day, so im pouring the oil into the motor and white smoke starts coming out. Didnt smell or anything, now i need an oil change but im not over my km yet. The oil was about at half.

Help :?

It was probably just hot…

dont worry nissans like 2 do what. I have done many oil changes and nissans like to do that the most.
Its condinsation.
