Hi Lowell, I agree with you, anywhere on the
oil cooler line system near the engine I think would be a more accurate temp source. On mine the
oil temp sensor is at the remote
oil filter mount in front of the engine, and the temps seem accurate. I used the other side of the mount to place a 20psi oil pressure switch which I wired to my dash red warning light, so if oil pressure falls and I'm not watching the gauge the warning light will get my attention for sure. I replaced my mechanical oil pressure gauge (tired of leaks) with a Smiths electric oil pressure gauge, it also seems to be very accurate. I had previously switched out the ammeter for a Smiths volt meter and installed a larger single wire alternator so my red warning light wasn't being used until I added the oil switch.
