I searched but couldn't really find what I was looking for. I just finished breaking in my engine after the rebuild and I'm switching over to synthetic. I want to run amsoil or royal purple (I gave up on Mobil 1) but my question is should I run 20W50 or I can get 15W40 in royal purple (I am located in south florida).
Also where do you guys buy your amsoil or oil products from?? Thanks in advance. I don't know much about oil. (flashpoints etc.)
