 Brian,Are you sure the black is from the o-ring.  My oil turns black from I assumed carbon off the brushes.  Hank

 Hi All,                I decided to try wd-40's new " silicon" spray , it started melting my O rings. Basically I noticed black coming off the O ring into the lubricant.    I have since gone back to another silicone spray which is an automobile product.  Does anyone have a preferred silicone product ?  I think my O rings are Buna
