Running thinner oil raised temps?
Hi guys, it's been a while since I have posted here, 2 jobs does that I guess :/.
Anyway, I finally got around to changing my oil after 9k miles (uhg) and I went from 5W-30 to 5W-20 and my engine temps went up 20F? I don't remember ever hitting 235F at night while driving home from work, and now I sit there for most of the drive. Also I run full synthetic if that means anything. I have some 5W-30 left of the same brand so I was considering putting some in to raise it but, I would like some input first.
