Leaded Fuel – Raw Figures

Explanation of the Figures

These are the raw figures of fuel consumption with my Triumph Spitfire whilst it was running on leaded petrol (4-star). The figures were used to create the graph of leaded fuel consumption.

The consumption figures are in miles per litre (mpl) as this is the easiest values to record in the UK now fuel is sold in litres. But for those who prefer miles per gallon (mpg) figures, a UK gallon is approx 4.5 litres. So:

9 mpl = 40.5 mpg
8 mpl = 36 mpg
7 mpl = 31.5 mpg
6 mpl = 27 mpg
