Would we admit the following experiment as valid:
(1) drive the same stretch of long highway multiple times & measure the temperature of underside of the differential (not the cover) with an infrared temperature sensor?
(2) change the differential cover & fluid
(3) drive the same stretch of long highway multiple times (at same ambient temperature) & measure the temperature of underside of the differential (not the cover) with an infrared temperature sensor?
When then compare the temperatures obtained in (1) against those in (3) to see if the fluid cooler.
I think you would have to change gear oil first, put the old cover back on, then check temps. Otherwise you are comparing worn possibly lower viscosity sheared oil against new oil with the new cover.
I thought about this, but it would be annoying to recapture the old fluid in a clean container. Is there an easy way to do this?
