@Robert M I carry a “long-stemmed candy thermometer” in my car. I’ve been sticking that down the dip stick on various intervals to see where I’m at.
I have a 1915cc engine in my VS, with a CB Performance 2 qt wide glide oil sump. As long as traffic is moving I’m fine (temps at or below 205-210). I’ve noticed when traffic comes to a halt, my oil temps rise (to the point where I need to immediately exit and drive around-in the opposite direction) when it’s 85 degrees or more outside.
This is why I now check traffic reports religiously on my trips. Plus being stuck in traffic is no fun anyway.
Is there a “solid” long term solution to relieving anxiety about my oil temps when stuck in obnoxious CA traffic on 85+ degree days with an AC engine? Or is the solution just to avoid those situations altogether?
