Yes, just about all Tesla's have about 2 quarts in each differential and an oil filter too. If you did not know that, now you do. Pretty simple service but if you plan to put 100k miles on the car you may want to consider this every 30k miles and if you end up tracking/racing your Tesla you may want to do this more frequently as there is not much oil in those differentials compared to the heat that is created. We also offer special oil filters with oil coolers attached. Click here to see the selection available at our store.
