Chevrolet Silverado (USA / CAN)
Differential fluid capacity & service interval
Chevrolet Silverado (USA / CAN) uses differential fluid with a capacity range of 4 to 5,9 liters. Service intervals include checking at 7500 miles and changing at 60000 miles. The data covers 3 configurations.

Additional Notes
- The rear differential on the Chevrolet Silverado HD 4500/5500/6500 6.6 Duramax V8 carries a capacity of 5.9 liters, a notably large fill volume consistent with the heavy-duty axle assemblies found on commercial-grade trucks in the 4500–6500 class.
- The 5.9-liter rear differential capacity applies under a vocational use condition, meaning the change interval of 60,000 miles is tied specifically to that demanding operational context rather than a standard passenger or light commercial duty cycle.
- The front differential on the AWD variant holds 4 liters, a meaningfully smaller volume than the rear, reflecting the different axle size and load-bearing role of the front assembly relative to the rear.
- The front differential fluid change interval on the AWD configuration is set at 60,000 miles under normal use conditions, aligning with the same mileage threshold as the rear despite the differing capacity and use classification.
- Both the non-AWD and AWD rear differential specifications share the same 5.9-liter capacity and 60,000-mile change interval under vocational use, indicating the rear axle assembly is consistent across those two drivetrain configurations starting from 2019.
- A check interval of 7,500 miles is specified across all three rows, applying to both the front and rear differentials regardless of drivetrain layout or use condition, placing fluid level inspection on a relatively frequent schedule given the 60,000-mile change interval.
