Knowing the correct differential oil capacity for your BMW E36 is crucial for maintaining optimal performance and preventing damage. The capacity typically ranges from 1.1 to 1.2 liters, but always verify the exact specification for your specific E36 model year and differential type. Regularly checking and replacing the differential oil ensures proper lubrication and extends the life of your E36's drivetrain. Refer to your owner's manual or a trusted BMW repair guide for detailed instructions on the correct procedure.
