I should have figured this actually. I have seen as much as a 25* drop in oil temps from switching to a synthetic from vehicles Ive serviced. Which it makes sense really, your reducing friction. I need to buy me one of those infra red thermometers and take an actual temperature reading and then put some of that stinky GM stuff back in there.
I dont think I would run anything else in there though, like a gear lube. At least at this point I dont think I would. I need to do some research first and see if there is any overlap in any of the gear lubes and motor oil and go from there. I dont mind experimenting a little, I have a spare snout if it came down to it.
