what about if the oil is black? I check my oil often and recently found it to be black. Does it affect the tractor?
Yep, just like Ken wrote...
The 790's oil was always nice and straw colored, just like fresh new oil. 670's wasn't quite as nice...4400's oil was just changed 15 hours ago.
But my old Silverado with the 6.2 ltr diesel was nasty within a few hours.
Unless you determine there is a need (oil contaminated by fuel, for example), I suggest you just go by the hours on it.
