Alfa Romeo's recommendation for the following cars (3L per vehicle):

Giulia Quadrifoglio

Differential RDU 230-TV: main case: 0.8 liters

Left side case: 0.5 liters

Right side case: 0.6 liters

Stelvio Quadrifoglio

Differential RDU 230-TV: main case: 0.9 liters

Left side case: 0.68 liters

Right side case: 0.61 liters

IMPORTANT:

Alfa states the differential is lifetime fill. We disagree with this. 

We recommended to replace the oil every 50-60K miles to remove all the abrasion which accrues during “normal use” and sooner if you are running the vehicle in “severe duty” (Please see your owners manual for Severe Duty/Heavy duty)
