Tata Aria

Additional Notes

• The Tata Aria 2.2 D rear differential holds 1.68 liters, while the limited slip variant of the same rear differential carries a slightly larger 1.77-liter capacity, reflecting the additional fluid volume required to lubricate the clutch pack mechanism inside a limited slip unit.
• On the 4x4 variant, the front differential holds 1.5 liters, which is notably less than the rear differential's 1.68-liter fill, a difference that corresponds to the generally smaller housing size of front differentials in this type of drivetrain layout.
• Under normal use conditions, the rear differential fluid change interval is set at 75,000 km, regardless of whether the unit is a standard or limited slip configuration.
• Under severe use conditions, the change interval for all rear differential configurations drops to 45,000 km, representing a 40 percent reduction compared to the normal use interval of 75,000 km.
• A first change only interval of 15,000 km applies under severe conditions across all differential positions on both the 2WD and 4x4 variants. An early drain at this mileage is associated with removing metal particles generated during the initial break-in period of gear and bearing surfaces.
• The front differential on the 4x4 variant shares the same three-tier interval structure as the rear units, with changes scheduled at 75,000 km for normal use, 45,000 km for severe use, and 15,000 km for the first severe-condition change.
• Capacity figures remain constant across all three use condition tiers for each differential position, meaning the 1.68-liter and 1.77-liter rear differential fills and the 1.5-liter front differential fill apply equally under normal, severe, and first-change-only service scenarios.
