Hi There Another 4 Matic Specific Question .

I Have Just Replaced Almost All My Fluid , Heading Ona Long Road Trip , First One With My Benz , Hoping Thier World Class Reliability Comes To Shine!!

Any How Rear Diff Fluid Was Replaced Last Night , And The Fluid I Beleive Is Supposed To Be 80 W 90 Hypoid Gear Oil Will Suffice , For Both Fron And Rear Diff, ? (2 Litres Approx Used On Rear End ) And What Came Out Was In Most Likely A Very Runny Fluid And Very Black Fluid. My Tech Said Look Original ??? Or Very Old .
