BAIC Senova BJ40

Differential fluid capacity & service interval

BAIC Senova BJ40 differential fluid capacity ranges from 1 to 2 liters. Service intervals require changes every 50000 km or 30 months. The data covers 10 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • Across all five power variants of the BAIC Senova BJ40 covered here — 150 kW, 160 kW, 165 kW, 170 kW, and 184 kW — the front differential fluid capacity is uniformly specified at 1 liter under normal use conditions.
  • The rear differential holds twice the fluid volume of the front, with a capacity of 2 liters across every power variant listed, reflecting the typically larger housing and greater load-bearing role of a rear axle differential.
  • A 2-liter rear differential capacity is a moderately sized fill for a body-on-frame or truck-derived platform, consistent with a unit designed for off-road-capable four-wheel-drive operation rather than a compact passenger car axle.
  • The change interval for both front and rear differential fluid is set at 50,000 km or 30 months, whichever comes first, under normal use conditions across all listed variants.
  • A 30-month time limit alongside the 50,000 km distance interval means that even low-mileage operation triggers a fluid change once two and a half years have elapsed, preventing fluid degradation from age alone.
  • The front and rear differential service intervals are identical at 50,000 km or 30 months for every power output variant, meaning both axles follow the same maintenance schedule in normal use.
  • No variation in capacity or service interval exists between the 150 kW, 160 kW, 165 kW, 170 kW, and 184 kW configurations, indicating that differences in engine output do not alter the differential fluid specifications for the 2023 BJ40.
