Fresh oil after the winter break?

Hello everybody! Jetz is going to start soon!! Next week I would like to start my Suzi. At the moment my battery is still loading. Jetz times a question: I bought my machine last year in November. The dealer has still fresh oil pure and fully filled up. So that the carburettor does not stick so much, I tipped in for the wintering of such a fuel supplement (hope of what has helped, one will see…) But what I actually wanted to know, I have to reboot new oil ve Or does it last for the winter, after all it was completely new before the wintering (I drove max. 2km).(Shortly to the bike: Suzuki GSF 650s bandit (year of construction 2005; driven kilometers 1,200 > from the previous owner) Thank you! Greetings, Basti
