[AT] Fw: Black oil after 8hrs in new engine

Sun Aug 10 07:30:01 PDT 2014

I must admit I've never had this problem with the gasoline engines I have rebuilt or bought.    My cub cadet kohler engine has 285 hours and still has clean oil when I change it.  But in your case there could have been an additive or something added at the factory discoloring the oil.

Like Steve, I would change the oil and not worry about it.  If I continue to see very dark oil without at least some improvement, I would probably call the factory.   Not sure they would say anything helpful, but like you this is so out of my normal experience I would want to bounce it off someone.

Now diesel - that's a different matter.
