I just changed my rear differential oil by following another thread on this forum. It looks was very dirty! The drain plug has magnet and it trap lots of metal particles on it. I would recommend you to change it after the break-in period. I have 5500miles so far..

Could I have gain some "free" hp by changing the gear oil to synthetic gear oil? just wondering since this is my first rwd car...

Thanks..
