Additional Notes

  • The Bristol 400 rear differential holds between 1.7 and 2.25 liters of fluid, a range that reflects acceptable fill variation rather than a fixed target volume.
  • A check interval of 3,000 miles is specified for normal use conditions, paired with a change interval of 6,000 miles under the same conditions.
  • The 6,000-mile change interval for normal use means the fluid in the rear differential is renewed relatively frequently by mid-twentieth century standards, which aligns with the mechanical tolerances and lubricant technology of that era.
