I started with the sensor mounted in a 4-port, firewall-mounted, two-can filter mount similar to what Dave seems to be describing. It seemed to measure way lower than what I expected, which is the reason I moved it. The delta was something like 20 degrees low in the filter mount. I attribute the lower reading to not having adequate oil flow around the sensor. In the filter mount, the sensor sits back in a sort of alcove. Up on the adapter, it stick into the middle of the flow.
