Okay...Im soooo confused!!! Someone PLEASE clarify this! I was always told..the thicker the oil.. as in 10w-30 the better for colder area..as in up North...Not only was I told this but reading around I noticed almost everyone from up North runs 10W-30! And you would think you would want a thicker oil in the winter...not the summer. I have read up on this after reading this forum and some say heavier is better in the winter and some say noo its needed for the summer..So someone who knows can you please clarify this!
