I've posted this info on Lat G before... and while it seems "odd" - since it's common for us to want to use "the best"... and we have come to embrace Synthetics. Not all applications want it. It's TOO slippery.

so just to play the devil's advocate, why then does Mark Williams recommend and supply Synthetic with their diffs? the guy who builds our center sections recommends Synthetics, I have only ever used synthetics with no issue UNTILL we had Currie build some third members and they will void the warranty if you use synthetics. all 3 of these companies use the same gears and diffs (because you really have no option) we have actually started to spec US Gear.as Motive seems to be really inconsistent.
I know this just confuses the matter but there seem to be some differences of opinion.
So when I finished my Nova we loaded it up at took it to the local road course. put 15 laps on it, this is brand new Royal Purple 85-140 gear oil, well SOMEONE didn't install a breather in the housing
it got SO hot and built up enough pressure that it pushed the pinion seal out. and all the oil with it. loaded the car in the trailer back to the shop......... 3 hours later it was still to hot to hold on to!! and that was with an Aluminum Center section also...no abnormal gear wear new seal oil off we go still running strong today.
i like synthetic
