Additional Notes

  • A 1.3-liter rear differential fluid capacity applies across the Mazda B, UF (EU) range for the B1600, B2000, and B2200 Diesel variants, covering both standard and limited slip rear differentials in each case.
  • The B2600 4x4 rear limited slip differential carries a notably higher capacity of 1.7 liters, compared to the 1.3-liter figure shared by all other rear differentials in the lineup. The additional volume reflects the greater internal complexity of a limited slip unit in a four-wheel-drive application.
  • The B2600 4x4 front differential holds 1.2 liters, the smallest capacity figure across all differential entries in the specification set, consistent with the typically smaller housing of a front axle differential in a part-time 4x4 truck.
  • All differential entries across every variant share identical service intervals: a fluid level check at 15,000 km or 12 months, and a full fluid change at 45,000 km or 36 months. Both intervals apply under normal use conditions.
  • The B2000 spans the widest model year range of the petrol variants, covering 1984-1994, while the B1600 appears only for 1985-1986. Despite the difference in production span, both share the same 1.3-liter rear differential capacity and identical service intervals.
  • The B2200 Diesel covers 1984-1997 and carries the same 1.3-liter rear differential capacity as the petrol B2000 and B1600, with no variation in fluid volume or service schedule between the diesel and petrol configurations.
  • The B2600 4x4, spanning 1985-1998, is the only variant in the specification set with a front differential entry, reflecting its four-wheel-drive drivetrain architecture. The remaining variants list only rear differential data.
