My notes say the Castrol BOT-750B is for the standard, non-e-diff. Jaguar p/n C2D3653, replaced by C2P25272. The Castrol BOT-720 is for the e-diff and the mechanical LSD.

ok perfect…I called a third dealership and gave them my vin # and they confirmed it’s the Castrol BOT 750 B, not the 720… due to the base having an open/ standard diff.

thanks for the quick response in helping to validate this.
