I read about this and I don ' t think a person will go completely crazy , but it does damage them in little ways . One sort of odd thing is the tendency of the person to obsess over something really small , like one inmate who became obsessed with the idea that his bladder was never completely empty , and would spend most of his hours trying to piss when he didn ' t have to . <| sep |> Should , can , could , allegedly , might , may have , etc . Headlines using these words often mean the story is just opinionated bullshit from a politically motivated writer . <| sep |> That ' s a great idea , thanks . I just changed it yesterday and didn ' t dispose of it yet . I poured it in a clear gallon jug . This was the first long term oil change , about 2500 miles on it . It was pretty dark but I don ' t see any signs of coolant . I ' ll check again after several days . If it was leaking internally , wouldn ' t I also see oil in my coolant ? Or is that not the case ?
