Someone please educate me. After months of research, I still don't understand oil weight and viscosity.
My main question is if 0W-20 and 5W-20 perform the same at operating temperature and most engine wear occurs at startup, why use 5W? Am I not understanding the concept? I have read the webpage "home" multiple times.
Why wouldn't all oil be 0W-xx so cold starts don't wear the motor as much.
