Additional Notes
- The Bristol 405 rear differential holds 1.7 liters of fluid, a figure consistent with the compact hypoid rear axle units common to British saloons of the late 1950s and early 1960s.
- Under normal use conditions, the Bristol 405 differential fluid change interval is set at 6,000 miles, reflecting the relatively short drain cycles typical of gear oils formulated during that era.
- A separate check interval of 3,000 miles is specified for normal use, meaning the fluid level is inspected at half the full change interval rather than waiting for the complete drain cycle.
