Why would the oil in the pan get dirty but the color of the oil in the filter stay as clear all season? This is a 1995 Ford 1620 3 cylinder shibaura diesel engine.
I do get oil in the oil filter but it stays clear and clean all season. I do not prefill the filter before fitting. After putting several hours or even a season on the 1995 Ford 1620 3 cylinder Sibaura engine, I pull the filter off and find clean oil but the oil in the oil pan is dirty.
