Additional Notes
- The Wolseley 18/85 and 18/85 automatic share identical brake fluid service intervals for the 1967-1972 period, with a check interval of every 5000 km or 3 months and a change interval of every 30000 km or 18 months.
- The Six and Six automatic, covering 1972-1975, carry a longer check interval of 10000 km or 6 months compared to the 18/85 variants, though the change interval of 30000 km or 18 months remains the same across all four configurations.
- All four configurations specify fluid level as between the minimum and maximum marks rather than a fixed volume, which is standard practice for hydraulic brake reservoirs where fluid is not consumed but monitored for loss or contamination.
- The 30000 km or 18 months change interval applies uniformly across both the 18/85 and Six generations, regardless of whether the transmission is manual or automatic.
- The check interval difference between the 18/85 (5000 km or 3 months) and the Six (10000 km or 6 months) means the earlier model required monitoring at twice the frequency of the later one under normal use conditions.
- All rows are designated for normal use conditions, meaning no separate severe-use interval is listed for any of the four configurations.
