The suitability of the fuel used for motor-sledging on Scott's last expedition, 1910–1913

ABSTRACT

The fuel used for motor-sledging during Scott's 1910–1913 expedition has been reanalysed to assess its suitability for that task in Antarctica. A research octane number of 65 and volatility were low compared with modern fuels but probably suitable when considering the design of the flathead engine. The findings are consistent with view that engine design was the primary cause of the mechanical failings.
