So this probably won't get any replies but I'm bored lol. I changed the oil yesterday. Ambient temp was 60 degrees. Engine had been off for a few hours so it was at or close to ambient. The EAO was not changed. This car has been on Amsoil ACD straight 30 for most of it's 74,000 miles. I filled it and waited about 15 minutes so any extra oil on the head would drain back. I pulled the fill cap off and had the girlfriend start it. I could barely see one cam lobe and two rockers. There was instantly splash, probably because the lobes sit in a pool of oil I'm assuming. The interesting thing was the flow. This oil at ambient temp was being flung and splashed around like I would expect a fully hot 20wt. Oil was going everywhere. I think if people would take the time to observe things like this the thick oil (within reason for the climate) fear would disappear. No lack of flow whatsoever. There was a steady stream of fast flowing oil going down one of the return holes through the head and this was with it cold. FWIW, the one lobe I could see looked brand new, it looked like the engine had never been fired.
