Hello, all! Thanks for the add. I recently picked up my 13 grabber blue GT500 with all options besides glass roof. I’m looking to change my differential oil and not sure what grade from the factory is used. I know it has the torsen diff and 3.31 gears. Is it full synthetic SAE 75W-85? Also, do you recommend to add the XL-3 motorcraft friction modifier for the torsen diff? Feedback would be greatly appreciated! Feel free to text me at 513-338-9761 if it’s more convenient.

You can't go wrong with OEM recommendations from the Owner's Manual.
FWIW, however, I prefer Amsoil Severe Gear 75W-90.
