Yes I've searched. Yes I've read about weight and temps. Yes I know this is a very opiniated topic. But I just want to go with popular vote.
I'm debating on rotella 5w-40 and 15w-40. I live in Washington and temps get low but not to the extremes(like 20F lowest. 80F summers. Average range) I daily my rig for now and just want to see what opinions you all have on which would make it run better between the 2. And yes I'm set on a Rotella oil. I just prefer it over others. Never done me wrong.
