A lot of D600 oil/dust spots but what to do? Is there a guide?

an "oil" spot, huh?

and how, exactly, did you determine it is oil, and not a speck of dust? they are not the same.

why don't you relax, use your camera and not fall victim to this hysteria?

a lot of people are having a field day hyping up this "issue," and humiliating a lot of well-meaning but naive D600 users, who are worrying instead of enjoying their cameras.

like the D800 "left AF issue," this one will die away as soon as some new product comes along as fodder for the bad news bears of the internet.
