Quick Question about Next oil change

[Kalel]

Hello all.. I have my Gz250... it is a 2006, It has only 300 miles. I bought it a month ago... It was garage kept and it is in excellent condition... My question is, when should I schedule the oil change? should I do it at 600 miles? I asked the seller and he told me he did not change the oil because it looked new when he checked it, but that he didn't know for sure and he recommended to change it when it hits 2K.

Thanks...
