Oil Spills with Nikon D7000? Is that recoverable?

Ok I decided to get Nikon D7000 and will do it soon, but lately saw some forum posts about oil spills issue - or not working good on a winter cold day - do other cameras have same problems and is it recoverable? As I read specs D7000 has self-cleaning system - has anyone experienced of using it and does it help for the oil spills? I'm not worried for hot pixels as I heard lot of dslr cameras have them - but oil spills - can it do damage on the lens as well?

I haven't heard similar things about D300s so I'm still wondering for which camera to go - it seems more stable in this aspect - or it also has issue problems?

Added (1). AW - the oil spills come from inside the camera while shooting not from outside - do more competent answers please

Spilling oil on any camera can damage it - regardless of brand or model. Learn to keep it away from oil.

The self cleaning system is not for oil spills, it is for keeping dust off the sensor.

I think you are talking about excessive lubrication when the camera was made, and not "oil spills" per se.

If this is what you are referring to, Canon had the same thing happen several years ago on the 1D series cameras. They released a list of affected serial numbers and took care of the problem for anyone whose camera was in that lot.

Since I did my research and knew of the issue beforehand, I checked the camera's serial number at the store before I bought it and made sure it was not in the affected range.

The lube problem has been sorted now. Wouldn't damage the lens though and nikon has fixed this.

D300s… You'd lose video (yes it has it but it's extremely primitive) and a stop of useable iso. It's also totally unsuitable for the untrained beginner
