I've always been able to read my dip stick until lately, it's been going wacky on me. I warm up the car after an oil change, the level goes over the second dot! What the heck am i doing wrong here? I place 4qts in. Is there something wrong? Well i just really want to know, what is the correct way of reading the dip stick? Also, what is the consequences for overfilling? My car seems to be shaking more than usual when i drive around 80mph. I have a 2000gsr so it's pretty new and shouldn't shake that much. Anyways thanks for the feedback guys.
