For those who change your oil at 3-4k because you feel the oil is 'used up' or 'worn out', what is your biggest concern about the oil:
A) the oil is full of dirt and abrasive metal that you want out of your engine;
OR
B) the oil has sheared out of grade, and you don't want thin oil in your engine;
Just curious about what peoples concerns are about their oil - this s NOT a 'bash the 3k crowd' thread!
