Yes, your Tesla model 3, Y, X or S has differential oil! Yes, you should have it changed at regular intervals. All Teslas, Especially Ludacris enabled and PLAID vehicles create tremendous power. Differentials are the gearing used to transfer the force from your electric motors to the CV drive shafts that propel the car. Service intervals are dependent on your vehicle’s drive train options. Tim’s has the specialized tools, filters and fluids to keep your Tesla differential in top shape.
