I took my daughter to her horse riding exam today. A round trip of 367.6 kilometres. The reported litres per 100 kilometres was 4.2. This must have been a good 4.2 because it was still at that level after the drive back through the 'burbs to home so I reckon more like 4.1-4.2.
So, for a total of 228.416 miles, the fuel consumption was 15.43 litres or 3.396 imperial gallons.
This makes my fuel consumption 67.2 miles per gallon!
