AMC Pacer
Differential fluid capacity & service interval
AMC Pacer differential fluid capacity ranges from 1,4 to 1,9 liters. Service intervals include checks every 12000 km or 8 months and changes every 48000 km or 30 months. The data covers 6 configurations.

Additional Notes
- The AMC Pacer rear differential holds 1.4 liters of fluid across all 232 and 258 six-cylinder configurations from 1975-1980, regardless of whether the axle is a standard or limited-slip unit.
- The V8-equipped Pacer from 1978-1980 carries a noticeably larger rear differential capacity of 1.9 liters, which reflects the physically larger axle housing typically paired with higher-torque engines.
- Both the standard and limited-slip rear differentials on the 232 and 258 engines share an identical 1.4-liter capacity, meaning the limited-slip clutch pack assembly within the carrier does not alter the total fluid volume required.
- The same capacity difference between six-cylinder and V8 configurations applies equally to both standard and limited-slip axle variants, with the V8 limited-slip differential also rated at 1.9 liters.
- A check interval of every 12,000 km or 8 months is specified under normal use conditions for all six configurations, indicating a relatively frequent monitoring schedule relative to the 48,000 km change interval.
- The fluid change interval of 48,000 km or 30 months applies uniformly across all engine variants and axle types under normal use, meaning neither the limited-slip designation nor the engine displacement alters the drain cycle.
- The time-based check interval of 8 months runs considerably shorter than the 30-month change interval, suggesting the specifications account for vehicles that may accumulate mileage slowly and still require periodic fluid condition assessment.
