I came to these forums a calm happy and contented 3000K with filter dino oil change guy. I now find myself questioning my whole life. How could I have made such a huge mistake? What a fool I've been! My life is a wreck and I need psychoanalysis. I can't sleep as I worry if I'm using exactly the right oil, at exactly the right time, for exactly the right application. I'm even discussing these issues with my wife! 0W-30? 10W-30? 10W-40? To syn or not to syn that is the question? I'm having to budget an extra $500 a year in UOA just to calm my nerves and allow me to function on a daily basis. This site should provide an on call psychiatrist for all the mental anxiety it's creating. Can somebody out there help me or should I just jump now?
