Sunbeam Alpine

Differential fluid capacity & service interval

Sunbeam Alpine uses differential fluid with a capacity of 1 liter. Service intervals include 9000 km, 9600 km, and 10000 km. The data covers 6 configurations.

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

Additional Notes

  • The Sunbeam Alpine rear differential holds 1 liter of fluid across all series from the 1953-1955 original through the Series V of 1965-1968, indicating a consistently small unit typical of lightweight British sports cars of the era.
  • The 1953-1955 Alpine has no change interval listed in the specifications, while every subsequent series from Series I onward carries a defined drain-and-refill interval under normal use conditions.
  • Series I (1959-1960) and Series II (1960-1963) share an identical service interval of 9600 km under normal use, alongside the same 1-liter capacity.
  • The Series III (1963-1964) and Series V (1965-1968) both specify a 10000 km change interval under normal use, the longest interval found across the Alpine range.
  • The Series IV (1964-1965) carries the shortest defined change interval of the series-designated models at 9000 km under normal use, sitting below the 9600 km of Series I and II and the 10000 km of Series III and V.
  • All change intervals across Series I through Series V are specified under normal use conditions, meaning the intervals reflect standard operating environments rather than severe or demanding duty cycles.
  • The variation in change intervals across Series I through Series V, ranging from 9000 km to 10000 km, reflects incremental adjustments across model revisions despite the rear differential capacity remaining fixed at 1 liter throughout.
