Anyone know why its recommended to change the rear Differential oil every 36K miles with the limited slip Differential? Seems very often to me and I assume it's filled with synthetic gear oil which should last unless the manufacturer feels it takes a beating and has to drain metal shavings that can damage the Differential or oil used breaks down that often they feel. Never heard of such an aggressive change schedule. If something were to happen if you didnt perform this fluid change you could be denied warranty coverage.
