1995 Buick Riviera Dirty Oil 1,000 Miles After Oil Change

Hi there,

The oil may look dirty because of the carbon build up in the engine, although it looks bad, its normally fine and you wont have a problem, you can try using a flushing agent next oil change as this will help clean out some of the muck, but as engine wear this carbon will build up as a natural part of the life of the engine.
