Guy comes up to me with black sludge on fingers saying my differential oil needed changing. I said this car has a sealed differential doesn't it? He said no. I said bo, I'll pass .
Was I being conned?
No, you weren't being conned, lol. There's no diff. in our diff. when it comes to removing the plug and changing/ adding gear oil. Depending on how many miles you have, it may indeed need to be changed.
